C3. PROCEDURE
C3.1 Weigh accurately about 20g of the biscuit powder (A3.3.2) in the previously weighed dish and ash in the muffle furnace at 600° ± 20°C until grey ash is obtained. Remove the dish from the furnace and allow it to cool at room temperature. Add 25 ml of the hydrochloric acid to the dish, cover with a watch glass and heat on a boiling water bath for 10 minutes. Mix the contents with tip of a glass rod and filter through What man filter paper No. 42 or its equivalent. Wash the filter paper with water until the washings are free from acid tasted with a blue litmus paper. Return the washed filter paper to the dish for ashing in the muffle furnace as above. Cool the dish in the desiccators and weigh. Again ignite the dish for half an hour in the furnace, cool and weigh. Repeat this operation until the dish has the constant mass. The difference between successive weighing being less than 1 mg. Filter paper, wash, ash and weigh it as in the case of acid insoluble ash. Substitute its mass from the mass of insoluble ash of the sample.
C4. CALCULATION
C4.1 Acid insoluble ash per cent by mass (A) = 100 (cm 1 – m)/ m2
Where
m1 = mass in g of the dish containing acid insoluble ash (see Note)
m = mass in g of empty dish in which the sample is taken for ashing, and
m2 = mass in g of the sample

7.4.2 Preparation of test specimens. Use the specimens that were used in the test given in 7.3 and in the case of condoms that were treated with propan -2°1, dry them to constant mass at temperature exceeding 37°C.
7.4.3 Procedure. Determine, to the nearest 0.01g the mass of each specimen.
7.5 TENSILE STRENGTH AND ELONGATION AT BREAK
7.5.1 Apparatus
The apparatus shall consist of:
(a) a cutting die consisting of two parallel knives (each having a cutting edge of length of at least 70mm) set 20mm apart in a press: and
(b) a tensile testing machine with a rate of travel of the moving jaw of 500mm/min and having, instead of normal clamps, 2 rollers each of diameter 15mm, one free to revolve on a bearing and the other rotated at a constant speed of about 7r/min.
7.5.2 Preparation of test specimens. After, in the case of condoms tested within 12 months of manufacture ageing 5 of the condoms in the sample (see 6.1.2(b) in accordance with 7.6, remove any dressing from the 10 condoms with propan –2ol.
Then, immediately immerse them in a suspension of talcum powder (of particle size not exceeding 1-m) in propan 2-01 and allow them to dry by hanging them open end upwards. From each of the condoms in the sample cut a test specimen as follows.
Lay the condom flat with its length at right angles to the cutting edges of the die, and from a smooth portion and with one stroke of the press, cut a specimen (in the form of a ring) from a region about 80mm away from the bead.
NOTE
To minimise errors in testing, take care to ensure that the ring specimen is cut at the right angles to the length of the condom. Discard and replace any specimen that has not been completely separated at the first attempt.
7.5.3 Procedure. Determine the mean single wall thickness of each test specimen then lay it flat and measure the distance between the two folded edges. Record twice this distance as the perimeter, P, of the specimen.
Place the ring over the roller of the tensile machine and stretch it until it breaks.
Record the maximum force registered before and the separation distance (between centres of the rollers) at break.
7.5.4 Calculations
(a) Calculate the strength and elongation at break of each specimen as follows:
Tensile strength, MPA=F/2wt
where F=the breaking load. N
w= the width of the test specimen, i.e. 20mm
t= the single wall thickness, mm
Elongation at break per cent K + 2D – P x 100/ P
Where K = length of test in specimen in contract with the rollers, mm (47mm with 15 mm diameter rollers).
P = original perimeter of specimen, mm
D = final distance between rollers, mm
(b) Disregarded the highest and lowest result obtained for each set of 5 or 10 (as relevant) specimens, and record then mean values of the remaining results as the tensile strength and elongation at break of the set.
7.6 AGING
Age the five condoms (in their envelopes) in accordance with ISO/R 188 but for only 12 hours, and then allow them to cool for at least 12 hours.
7.7 FREEDOM FROM HOLES
7.7.1 Apparatus
The apparatus shall consist of:
(a) amount, which is suitable equipment for suspending a condom by its open end allowing it to be filled (after mounting) with water;
(b) platform, placed about 200mm below the mount to support a filled condom; and
(c) dry absorbent paper (preferably coloured)
7.7.2 Test specimen. The test specimen shall be the condom retained in terms of 7.2.
7.7.3 Procedure. After, when applicable, rolling the condoms over a separate sheet of absorbent paper to remove surplus lubricant applied during manufacture, fit the open end of the condom under test on the mount, secure it (by means of the rubber ring) and pour into it 300ml of water at room temperature.
After about 1 minute inspect for leakage through the wall. If there is no sign of leakage, carefully remove the condom from the mount, and close the open end tightly by twisting the walls near the bead. Roll the water filled condom firmly at least twice over a sheet of the dry absorbent paper and inspect the paper for signs of leakage. Record a condom that shows any sign of leakage (in either stage of the test) as defective.
7.8 BLEEDING
7.8.1 Equipment. Dry, white absorbent paper.
7.8.2 Test specimens. The 10 condoms in the sample drawn in accordance with 6.1.2(c).
7.8.3 Procedure. Thoroughly wet each specimen (inside and out) with tap water but no attempt to remove any dressing material. Wrap each wet specimen (separately) in a piece of the absorbent paper that the largest possible surface area of the specimen is in contact with the paper, and place the assembly in a suitable air tight container that will prevent loss of moisture. After 16 hours remove from the container and remove absorbent paper and examine it visually, in natural daylight, for any indication of colour transfer.
7.9 DETERMINATION OF PH VALUE OF AQUEOUS EXTRACT
7.9.1 Apparatus. A ph metre.
7.9.2. Test specimens. The 10 condoms in the sample drawn in accordance with 6.1.2 (d).
7.9.3 Procedure. Immerse each specimen (separately) in 100 ml of distilled water for 48 hours, and then determine ph value of each extract.
7.10 ANALYSIS OF SPERMICIDAL AGENT
The identification of the spermicidal and its measured quantity shall be determined using the appropriate method described in the current edition of the US Pharmacopoeia.
7.11 DETERMINATION OF BURSTING VOLUME AND PRESSURE
7.11.1 Apparatus. Inflation apparatus, suitable for inflating the condom with clean, oil-free and moisture-free air at a specified rate, provide with equipment for measuring volume and pressure having the following feature:
(a) a pressure sensor configured such that there is no pressure differential between the condom and the pressure sensor;
(b) an apparatus for recording the volume of inflation air, configured such that there is no pressure differential between the measuring device and the condom, thereby ensuring that the volume of air is measured at the appropriate pressure within the condom and not at the line pressure which may be higher;
(c) a rod of suitable length having smooth sphere or hemisphere 25mm in diameter at its top hanging the unrolled condom when the condom is clamped the length of condom, excluding there reservoir remaining for inflation is (150 ± 3) mm.
(d) Pressure and volume measuring equipment capable of:
(i) a maximum permissible limit of error = 3% for volumes greater than 101, whatever method issued to measure volume;
(ii) measuring the pressure at bursting of the condom with a maximum permissible limit of error of 0.05kpa.
(e) a clamping device and clamping ring, having no sharp edges or protrusions and being of the recommended integral diameter 38 mm, recommended height 50 mm and the recommended material of constructional being transparent plastic; and
(f) an inflation cabinet having a facility for viewing the condom during inflation, and being of sufficient size to allow the condom to expand freely without touching any part of the cabinet.
7.11.2 Procedure. Carry out the test under controlled conditions of (25 ± 5)°C and (50 ± 60)% relative humidity.
Move the condom inside the package is such that it is away from the area where the package is to be torn. Tear the package and remove the condom.
The person testing shall not in any circumstances use scissors or other sharp instruments to open the package. Unroll the condom ensuring that it is not excessively stretched in any direction.
NOTE
The condom may be unrolled directly onto the rod of the test equipment. Hang the condom on the rod and affix to the mount. Take care when placing the clamping ring on its mount to avoid damaging or stretching the condom. Inflate with air at rate of (0.4 to 0.5) dm3/s (24 to 30) dm3/min figures check to ensure that the condom expands and that there are no obvious leaks.
If the condom exhibits any obvious leaks, or are detected during the inflation discontinue the test. The condom shall then be recorded as defective and bursting volume and pressure recorded as zero.
If the condom does not leak, measure and not the bursting volume in cubic decimeters rounded to the 1.0dm3and the bursting pressure, in kilopascals rounded to the nearest figure 1.0kpa.

8.9.2 Method
(a) Switch on the instruments for about half an allow it to warm up with the cell holder in the raised position and the main dial set so that curser line (blank) is immediately over the red line. Move the galvanometer spot coincide. Operate the tapping key and rotate the adjust Zero until the galvanometer sport does not move from its zero position showing that both photo cells are receiving the same amount of light.
(b) Prepare a flour paste by mixing together in a beaker 30g of flour and 10ml of distilled water. Mix the flour with a glass rod into a paste for 45 seconds and pour into the clean glass cell, the later being held at an angle so that the working face is down wards thus obviating difficulties from air bubbles on reflecting surface.
(c) Insert the sample cell into the upper half of the cell holder of the instrument operate the galvanometer key and then adjust zero control to check that the instrument is still balanced. Then carefully depress the cell holder into the down position. Operate the galvanometer key and rotate the main dial again until the galvanometer spot does not move. Read the grade figure directly of the scale of the instrument.
(d) Raise the holder cell holder and remove the sample cell, reset the main dial line value. The instrument is then for the next test.
Precaution
Make sure that the time of the test from the commencement of the mixing of the flour paste to the actual reading of the result is between 90-120 seconds.
If the time is less than 90 seconds, it will usually be found that the grade figure recorded is on the low side while if a longer time is taken over the test, the grade value found will be on the high side.

Packing and Marking
4.3 Packaging
The condition of the drums and bulk tankers into which the petrol is filled shall be such as not to be detrimental to the quality of the fuel during normal transportation and storage. Drums and containers shall be acceptably sealed and in addition shall conform to the Petroleum Act, Chapter 435 of the Laws of Zambia.
4.4 Marking
The following information shall appear in legible and indelible marking on each container or in the case of gasoline filled into bulk storage tanks, in the storage and consignment documents of each road tanker or rail wagon:
(a) the suppliers’ and receivers’ name and address;
(b) the type of fuel, i.e. Unleaded Petrol (Gasoline);
(c) the quantity in litres; and
(d) the batch/lot number.
5. Method of Test
For all characteristics, use the applicable method listed in column 3 of Table
5.1. Reid Vapour Pressure
5.1.1 When testing fuels containing no alcohol, use test method ASTM D323.
5.1.2 When testing fuel blends containing oxygenates in the form of alcohols or alcohol/ether mixtures, use test method ASTM D4953.
Note: When alcohol is present in fuel, the water introduced when test method
ASTM D 323 or IP 69 is used will extract some of the alcohol, causing low Reid Vapour Pressure values to be obtained.
5.2 Flexible Volatility Index (FVI)
The flexible volatility index is another parameter that characterises the
volatility properties of petrol, and is calculated using the formula:
FVI = RVP + 0.7 E70
where RVP is the vapour pressure in kilopascals; and E70 is the percentage of petrol, by volume, evaporated to 70°C
6. Sampling
6.1 Sampling from storage tanks
For the purposes of this Zambian Standard all sampling shall be carried out in accordance with the relevant procedures of ZS 396 Part 1 and, additionally, as detailed in 7.2.
Note: Attention is drawn to the special precautions needed for samples for the determination of Reid Vapour Pressure.
6.2 Sampling from petrol pumps
6.2.1 Sampling cans of 5 litres and 1 litre capacity. The construction of the cans shall comply with the appropriate safety requirements for cans that are to hold highly flammable material. They shall be provided with screw caps incorporating a petroleum resistant washer in good condition. A stock of cans shall be kept solely for the purpose of taking gasoline samples.
6.2.2.Preparation of cans. New cans shall be rinsed with gasoline before being used, to remove any residual traces of oil left during manufacturing operations, and then allowed to dry. Before use, all cans shall be checked to ensure that they are sound and free from leaks.
6.2.3 Sampling procedure. From the pump nozzle, 5 litres of gasoline shall be drawn carefully into a cool 5-litre can using a clean dry funnel. Immediately afterwards, this sample shall be decanted carefully into the requisite number of 1 litre cans, using a funnel, filling the cans within 15 mm of the brim.
If more than 5 litres are needed, the operation shall be repeated immediately and before the pump has been used for any other purpose. The screw caps shall be tightened fully and the cans checked to ensure that there are no leaks.
The sampling procedure shall not be carried out in direct sunlight.
Notes 1. If carried out in direct sunlight, changes in fuel quality, especially octane level, may occur.
2. A quantity of 1 litre is sufficient for the determination of octane number and certain other tests but it is advisable to provide each laboratory with 2 litres of sample in case further work is needed; it is essential that these 2 litres be of identical material.
6.2.4 Storage, labeling and transport. Samples shall be kept in a cool place although it is not necessary to keep them refrigerated.
Notes 1. If left in direct sunlight there is a danger that the cans will balloon.
Full and legible information relating to the source of the sample shall be attached to the can in such a manner that it will not easily become detached subsequently.
2. If required, the sample may be sealed and labeled to maintain its legal integrity.
3. If the sample has to be sent to a laboratory by public transport, it will be necessary to comply with the general regulations for the transportation of flammable materials and with the requirements of the transport authority concerned. Information on the appropriate procedures and the type of packaging required should be obtained from the transport authority involved.

4 Cement
Cement is a hydraulic binder, i.e. a finely ground inorganic material which, when mixed with water, forms a paste which sets and hardens by means of hydration reactions and processes and which, after hardening, retains its strength and stability even under water.
Cement conforming to EN 197-1, termed CEM cement, shall, when appropriately batched and mixed with aggregate and water, be capable of producing concrete or mortar which retains its workability for a sufficient time and shall after defined periods attain specified strength levels and also possess long-term volume stability.
Hydraulic hardening of CEM cement is primarily due to the hydration of calcium silicates but other chemical compounds may also participate in the hardening process, e.g. aluminates. The sum of the proportions of reactive calcium oxide (CaO) and reactive silicon dioxide (SiO2) in GEM cement shall be at least 50 % by mass when the proportions are determined in accordance with EN 196-2.
CEM cements consist of different materials and are statistically homogeneous in composition resulting from quality assured production and material handling processes The link between these production and material handling processes and the conformity of cement to EN 197-1 is elaborated in EN 197-2.
Note There are also cements whose hardening is mainly due to other compounds, e.g. calcium aluminate in calcium aluminate cement.
5 Constituents
5.1 General
The requirements for the constituents specified in 5.2 to 5.5 shall be determined in principle in accordance with the test methods described in EN 196 unless otherwise specified.
5.2 Main constituents
5.2.1 Portland cement clinker (E)
Portland cement clinker is made by sintering a precisely specified mixture of raw materials (raw meal, paste or slurry) containing elements, usually expressed as oxides, CaO, SiO2, A12O3, Fe2O3 and small quantities of other materials. The raw meal, paste or slurry is finely divided, intimately mixed and therefore homogeneous.
Portland cement clinker is a hydraulic material which shall consist of at least two-thirds by mass of calcium silicates (3CaO.SiO2 and 2CaO.SiO2), the remainder consisting of aluminium and iron containing clinker phases and other compounds. The ratio by mass (CaO)/(SiO2) shall be not less than 2.0. The content of magnesium oxide (MgO) shall not exceed 5.0 % by mass.
5.2.2 Granulated blastfurnace slag (S)

5.2.3 Pozzolanic material (P, Q)
5.2.3.1General
Pozzolanic materials are natural substances or industrial pozzolanas, siliceous or silico- aluminous, or a combination thereof. Although fly ash and silica fume have pozzolanic properties, they are specified in separate clauses (see 5.2.4 and 5.2.7).
Pozzolanic materials do not harden in themselves when mixed with water but, when finely ground and in the presence of water, they react at normal ambient temperature with dissolved calcium hydroxide (Ca (OH) 2) to form strength-developing calcium silicate and calcium aluminate compounds. These compounds are similar to those which are formed in the hardening of hydraulic materials. Pozzolanas shall consist essentially of reactive SiO2 and Al2O3. The remainder contains Fe2O3 and other oxides. The proportion of reactive Ca03) is negligible. The reactive SiO2 content shall be not less than 25 % by mass.
Pozzolanic materials shall be correctly prepared, i.e. selected, homogenised, dried and comminuted, depending on their state of production or delivery.
5.2 3.2 Natural pozzolana (P)
Natural pozzolanas are usually substances of volcanic origin or sedimentary rocks with suitable chemical and mineralogical composition and shall conform to 5.2.3.1.
5.2.3.3 Natural calcined pozzolana (Q)
Natural calcined pozzolanas are materials of volcanic origin, clays, shales or sedimentary rocks, activated by thermal treatment and shall conform to 5.2.3.1.
5.2.4. Fly ashes (V, W)
5.2.4.1 General
Fly ash is obtained by electrostatic or mechanical precipitation of dust-like particles from the flue gases from furnaces fired with pulverised coal. Ash obtained by other methods shall not be used in cement that conforms to EN 197-1.
Fly ash may be siliceous or calcareous in nature. The former has pozzolanic properties; the latter may have, in addition, hydraulic properties The loss on ignition of fly ash determined in accordance with EN 196-2, but using an ignition time of 1 h, shall not exceed 5.0 % by mass.
Fly ash with loss on ignition of 5.0 % to 7.0 % by mass may also be accepted, provided that particular requirements for durability, especially frost resistance, and for compatibility with admixtures are met according to the appropriate standards and/or regulations for concrete or mortar in the place of use. In the case of fly ash with a loss on ignition between 5.0 % and 7.0 % by mass the maximum limit, 7.0 %, shall be stated on the packaging and/or the delivery note of the cement.
5.2.4.2 Siliceous fly ash (V)
Siliceous fly ash is a fine powder of mostly spherical particles having pozzolanic properties. It consists essentially of reactive silicon dioxide (SiO2) and aluminium oxide (Al2O3). The remainder contains iron oxide (Fe2O3) and other compounds.
5.2.4.3 Calcareous fly ash (W)
Calcareous fly ash is a fine powder, having hydraulic and/or pozzolanic properties. It consists essentially of reactive calcium oxide (CaO), reactive silica (SiO2) and aluminium oxide (Al2O3). The remainder contains iron oxide (Fe2O3) and other compounds. The proportion of reactive calcium oxide shall not be less than 10.0% by mass. Calcareous fly ash containing between 10.0 and 15.0 % mass of reactive calcium oxide shall contain not less than 25.0 % by mass of reactive silica.
Adequately ground calcareous fly ash containing more than 15.0 % by mass of reactive calcium oxide, shall have a compressive strength of at least 10.0 MPa at 28 days when tested in accordance with EN 196 – 1. Before testing, the fly ash shall be ground and the fineness, expressed as the proportion by mass of the ash retained when wet sieved on a 40 nm mesh sieve, shall be between 10 % and 30 % by mass. The test mortar specimens shall be demoulded 48 h after preparation and then cured in a moist atmosphere of relative humidity of at least 90 % until tested.
The expansion (soundness) of calcareous fly ash shall not exceed 10 mm when tested in accordance with EN 196-3 using a mixture of 30 % by mass of calcareous fly ash ground as described above and 70 % by mass of a CEM I cement conforming to EN 197-1.
Note If the sulphate (SO3) content of the fly ash exceeds the permissible upper limit for the sulphate content of the cement then this has to be taken into account for the manufacture of the cement by appropriately reducing the calcium sulphate- containing constituents.
5.2.5 Burnt shale (T)
Burnt shale, specifically burnt oil shale, is produced in a special kiln at temperatures of approximately 800 °C. Owing to the composition of the natural material and the production process, burnt shale contains clinker phases, mainly dicalcium silicate and monocalcium aluminate. It also contains, besides small amounts of free calcium oxide and calcium sulphate, larger proportions of pozzolanically reacting oxides, especially silicon dioxide. Consequently, in a finely ground state burnt shale shows pronounced hydraulic properties like Portland cement and in addition pozzolanic properties.
Adequately ground burnt shale shall have a compressive strength of at least 25.0 MPa at 28 days when tested in accordance with EN 196 – 1. The test mortar shall be prepared with finely ground burnt shale instead of cement. The mortar specimens shall be demoulded 48 h after preparation and cured in a moist atmosphere of relative humidity of at least 90 % until tested.
The expansion (soundness) of burnt shale shall not exceed 10 mm when tested in accordance with EN 196-3 using a mixture of 30 % by mass of ground burnt shale and 70 % by mass of a CEM I cement conforming to EN 197-1.
Note If the sulfate (SO3) content of the burnt shale exceeds the permissible upper limit for the sulfate content of the cement then this has to be taken into account for the manufacture of the cement by appropriately reducing the calcium sulfate-containing constituents.
5.2.6 Limestone (L, LL)
Limestone shall meet the following requirements:
(a) The calcium carbonate (CaCO3) content calculated from the calcium oxide content shall be at least 75 % by mass.
(b) The clay content, determined by the methylene blue test in accordance with EN 933-9,
shall not exceed 1.20 g/100 g. For this test the limestone shall be ground to a fineness of approximately 5000 cm2/g determined as specific surface in accordance with EN 196-6.
(c) The total organic carbon (TOC) content, when tested in accordance with prEN 13639: 1999, shall conform to one of the following criteria:
– LL: shall not exceed 0.20 % by mass;
– L: shall not exceed 0.50 % by mass.
5.2.7 Silica fume (D)
Silica fume originates from the reduction of high purity quartz with coal in electric arc furnaces in the production of silicon and ferrosilicon alloys and consists of very fine spherical particles containing at least 85 % by mass of amorphous silicon dioxide.
Silica fume shall meet the following requirements:
(a) The loss on ignition shall not exceed 4.0 % by mass determined in accordance with EN
196-2 but using an ignition time of 1 h.
(b) The specific surface (BET) of the untreated silica fume shall be at least 15.0 m2/g when tested in accordance with ISO 927?.
For intergrinding with clinker and calcium sulfate the silica fume may be in its original state or compacted or pelletised (with water).
5.3 Minor additional constituents
Minor additional constituents are specially selected, inorganic natural mineral materials, inorganic mineral materials derived from the clinker production process or constituents as specified in 5.2 unless they are included as main constituents in the cement.
Minor additional constituents, after appropriate preparation and on account of their particle size distribution, improve the physical properties of the cement (such as workability or water retention). They can be inert or have slightly hydraulic, latent hydraulic or pozzolanic properties. However, no requirements are set for them in this respect.
Minor additional constituents shall be correctly prepared, i.e. selected, homogenised, dried and comminuted depending on their state of production or delivery. They shall not increase the water demand of the cement appreciably, impair the resistance of the concrete or mortar to deterioration in any way or reduce the corrosion protection of the reinforcement.
Note Information on the minor additional constituents in the cement should be available from the manufacturer on request.
5.4 Calcium sulfate
Calcium sulfate is added to the other constituents of cement during its manufacture to control setting.
Calcium sulfate can be gypsum (calcium sulfate dihydrate, CaS04.2H20), hemihydrate (CaS04.12H O), or anhydrite (anhydrous calcium sulfate, CaS04) or any mixture of them. Gypsum and anhydrite are found naturally Calcium sulfate is also available as a by-product of certain industrial processes.
5.5 Additives
Additives for the purpose of EN 197-1 are constituents not covered in 5.2 to 5.4 which are added to improve the manufacture or the properties of the cement.
The total quantity of additives shall not exceed 10 % by mass of the cement (except for pigments). The quantity of organic additives on a dry basis shall not exceed 0.5 % by mass of the cement.
These additives shall not promote corrosion of the reinforcement or impair the properties of the cement or of the concrete or mortar made from the cement.
When admixtures for concrete, mortar or grouts conforming to the EN 934 series are used in cement the standard notation of the admixture shall be declared on bags or delivery documents.
6 Composition and notation
The 27 products in the family of common cements, covered by EN 197-1, and their notation are given in Table 1. They are grouped into five main cement types as follows:
– CEM I Portland cement
– CEM II Portland-composite cement
– CEM III Blastfurnace cement
– CEM IV Pozzolanic cement
– CEM V Composite cement
The composition of each of the 27 products in the family of common cements shall be in accordance with Table 1.
Note For clarity in definition, the requirements for the composition refer to the sum of all main and minor additional constituents. The final cement is to be understood as the main and minor additional constituents plus the necessary calcium sulfate (see 5.4) and any additives (see 5.5),

9.2 Conformity criteria for mechanical, physical and chemical properties and evaluation procedure
9.2.1 General
Conformity of cement with the requirements for mechanical, physical and chemical properties in EN 197-1 is assumed if the conformity criteria specified in 9.2.2 and 9.2.3 are met. Conformity shall be evaluated on the basis of continual sampling using spot samples taken at the point of release and on the basis of the test results obtained on all auto-control samples taken during the control period.
9.2.2 Statistical conformity criteria 9 2 2 1 General
Conformity shall be formulated in terms of a statistical criterion based on:
– the specified characteristic values for mechanical, physical and chemical properties as given in 7.1,7.2, and 7.3 of EN 197-1;
– the percentile Pk, on which the specified characteristic value is based, as given in Table 5;
– the allowable probability of acceptance CR, as given in Table 5.

Note Conformity evaluation by a procedure based on a finite number of test results can only produce an approximate value for the proportion of results outside the specified characteristic value in a population. The larger the sample size (number of test results), the better the approximation. The selected probability of acceptance CR controls the degree of approximation by the sampling plan.
Conformity with the requirements of EN 197-1 shall be verified either by variables or by attributes, as described in 9.2.2.2 and 9.2.2.3 as specified in Table 4.
The control period shall be 12 months.
9.2.2.2 Inspection by variables
For this inspection the test results are assumed to be normally distributed.
Conformity is verified when equation(s) (1) and (2), as relevant, are satisfied:
~X – kA x s e” L (1)
and
X+kAxsd”U (2)
where
X’s arithmetic mean of the totality of the auto-control test results in the control period;
s is the standard deviation of the totality of the auto-control test results in the control period;
kA is the acceptability constant;
L is the specified lower limit given in Table 2 referred to in 7.1;
U is the specified upper limit given in Tables 2 and 3 referred to in clause 7.
The acceptability constant kA depends on the percentile Pk on which the characteristic value is based, on the allowable probability of acceptance CR and on the number n of the test results. Values of kA are listed in Table 6.

c For pre-stressing applications cements may be produced according to a lower requirement. If so, the value of 0.10 % shall be replaced by this lower value which shall be stated in the delivery note.
9.3 Conformity criteria for cement composition
At least once per month the composition of the cement shall be checked by the manufacturer, using as a rule a spot sample taken at the point of release of the cement. The cement composition shall meet the requirements specified in Table 1.

Annex ZA
(Informative) Provisions for the CE marking of common cements under the EU Construction Products Directive
ZA.1 Clauses of EN 197-1 addressing the provisions of EU Construction Products Directive
EN 197-1 and this Annex ZA have been prepared under a mandate 2) given to CEN by the European Commission and the European Free Trade Association.
The clauses of EN 197-1, shown in Table ZA.l, meet the requirements of this Mandate given under the EU Construction Products Directive (89/106/EEC).
Compliance with these clauses confers a presumption of fitness of common cements covered by EN 197-1 for the intended use(s) under consideration in Table ZA.2.
Warning Other requirements and other EU Directives, not affecting the fitness for
intended use(s), can be applicable to a construction product falling within the scope of EN
197-1.
There may be requirements on dangerous substances applicable to the products falling within the scope of EN 197-1 (e.g. transposed European legislation and national laws, regulations and administrative provisions). In order to meet the provisions of the EU Construction Products Directive, these requirements need also to be complied with, when and where they apply.
Note. An informative database of European and national provisions on dangerous substances is available at the Construction website on EUROPA (CREATE, accessed through http:// europa.eu.intV

|
APPENDIX B |
|
Recommendation Code Practice for Users Antistatic Protective or Safety Footwear |
|
This conductive footwear has been produced to the performance standards required in accordance with ZS 073: Part I specification for industrial leather safety footwear for general and heavy duty use. |
|
Electrically conducting footwear should be used if it is necessary to minimise electrostatic build-up by dissipating electrostatic charges in the shortest possible time, e.g. when handling explosives, and if the risk of electric shock from any electrical apparatus has been completely eliminated. |
|
In order to ensure that this footwear is definitely conducting, it has been manufactured to have an upper limit of less than 1.5 x 105 in its new state. |
|
During service, the electrical resistance of footwear made from conducting material may change significantly due to flexion or contamination. It is therefore, necessary to ensure that the product is capable of fulfilling its designed function of dissipating electrostatic charges during the whole of its life. The user is strongly recommended to carry out the test for electrical resistance at regular and frequent intervals. |
|
If the footwear is used in conditions where the soling material becomes contaminated, wearers should always check the electrical properties of their footwear prior to entering a hazard defined area. |
|
Where conducting footwear is in use, the resistance of the flooring should be such that it does not invalidate the protection against static electricity provided by the footwear. |
|
In use, no insulating elements should be introduced between the inner sole of the footwear and the foot of the wearer. |
|
APPENDIX C |
|
Recommendation Code Practice for Users Antistatic Protective or Safety Footwear |
|
This antistatic footwear has been produced to the performance standards required accordance with ZS 073: Part 1 – specification for industrial safety footwear for general and heavy duty use. |
|
Antistatic footwear should be used if it is necessary to minimise electrostatic build-up, by dissipating electrostatic charges, thus avoiding the risk of spark ignition of flammable liquids and vapours, etc and if the risk of electric shock from any electrical apparatus has not been eliminated. |
|
Experience has shown that, for antistatic purposes, the discharge patch through a product should normally have an electrical resistance of less than 108 at any time throughout its useful life. A value of 5 x 104 is specified as the lowest limit of resistance when new in order to ensure adequate protection against dangerous electric shock or ignition in the event of electrical apparatus becoming defective when operating at voltages up to 250 v. |
|
This leathered upper, antistatic footwear is so designed that the electrical resistance of the outsole complex meets these requirements. |
|
The electrical resistance of this footwear may be changed significantly by flexing, contamination or moisture and will not perform its intended function if worn in wet conditions. If is therefore, necessary to ensure that the product is capable of fulfilling its designed function of dissipating electrostatic charges and also giving any desired protection during the whole of its life. The user is strongly recommended to carry out the test for electrical resistance at regular and frequent intervals. |
|
If the footwear is worn under conditions where the soling material may become contaminated, wearers should always check the electrical properties of the footwear prior to entry into any defined hazardous area. |
|
Where antistatic footwear is in use, the resistance of the flooring should be such that it does not invalidate the protection against mains shock or static electricity provided by the footwear. |
|
In use, no insulating elements should be introduced between the inner sole of the footwear and the foot of the wear. |

Cover the dish while still in the oven and transfer to a desiccator, containing re-ignited calcium oxide as drying agent. Weigh the dish and cover soon after it reaches room temperature. The loss in mass is reported as moisture per cent. |
|
ANNEX J |
|
DETERMINATION OF CRUDE PROTEIN |
|
J.1 Reagent |
|
All reagents shall be of analytical reagent quality and the water used shall be distilled water, or water of equal purity. |
|
J.1.1 Sulphuric acid (Concentrated) |
|
J.1.2 Sodium hydroxide (Concentrated) |
|
J.1.3 Indicator solution. Dissolve 0. 2 g each of methyl red and methylene blue indicators in a little water in a 500 ml volumetric flask and make up to the mark. |
|
J.l.4 Sodium hydroxide solution, 0.1 N or sulphuric acid, 0.1 N standardised. |
|
J.1.5 Boric acid solution, 4 % m/v |
|
J.1.6 Receiver solution, dilute 8 ml of methyl red/methylene blue mixed indicator solution with a litre of 4 % boric acid. |
|
J.1.7 Selenium, Kjeldahl catalyst tablets. |
|
J.2 Procedure |
|
Weigh accurately about 1 g of a finely ground sample and transfer to a 500 ml Kjeldahl flask containing 5 tablets of the selenium catalyst (or 8 g if it is in powder form) and 20 ml of concentrated sulphuric acid. Mix the contents of the flask, heat gently, until frothing has ceased, boil gently until the liquid is clear and then boil for 1.5 hours taking care that the flask is not directly heated above the level of the contents. |
|
When the digest is cool, add 150 ml of water, mix and add a few drops of antifoaming agent and 70 ml of concentrated sodium hydroxide poured down the side of the flask to form a bottom layer. |
|
Connect the flask to a condenser, with tight-fitting rubber stopper, the tip of which is immersed in 50 ml of receiver solution (K.1.6) contained in a 250 ml conical flask. Gently rotate the Kjeldahl flask to mix its contents thoroughly. Boil until all the ammonia has distilled (check with red litmus paper). Lower the conical flask to bring the tip of the condenser above the receiver solution and rinse the outside of the tip with water. Repeat the whole procedure with 5 ml of water in place of the sample for a blank determination. |
|
Titrate the sample and blank distillates to the same end point with standardised sodium hydroxide solution or standardized sulphuric acid solution. Subtract the sample titration from the blank titration to obtain the volume of standardised sodium hydroxide or sulphuric acid solution equivalent to the total nitrogen in the mass of sample taken. [1 ml of 0.1 N sodium hydroxide or sulphuric acid solution is equal to 0.0014 g of nitrogen] To obtain the percentage by mass of protein in the sample, multiply the percentage of total nitrogen by 6. 25. |
|
ANNEX K |
|
DETERMINATION OF FREE FATTY ACID |
|
K.1 Reagents |
|
K.1.1 Petroleum ether, (BP 40 – 60°C)3. |
|
K.1.2 Phenophthalein indicator, 5 g/m in methanol 50 % v/v. |
|
K.1.3 Sodium hydroxide, 0.1N standard volumetric solution. |
|
K.1.4 Ether or ethanol solution, 50: 50. Mix 225 ml diethyl ether, 225 ml methylated spirit and 50 ml of phenolphthalein indicator. |
|
K.2 Procedure |
|
Weigh accurately a dry and clean extraction flask. Weigh accurately 5 g of a thoroughly dried and finely ground sample and transfer into the extraction flask. |
|
Extract the oil with about 50 ml petroleum ether, contained in the flask which is now attached to a tube fitted with a cooling system. |
|
Detach the flask after 4 hours and dry off the excess solvent. Place the flask in an oven at 100°C to remove any moisture for 10 minutes, cool the flask in a desiccator and weigh the flask again. Dissolve the oil in about 2.5 ml 50:50 ether/ ethanol solution. Warm the contents a little and shake the flask, titrate with 0.1 N sodium hydroxide solution, to a faint pink colour. |
|
The end point of the titration is reached when the addition of a single drop produces a slight but definite colour change persisting for at least 15 seconds. |
|
K.3 Calculation |
|
The acidity expressed as percentage by mass of oleic acid, is given by the formula: 28. 2 (VN/m) |
|
Where: |
|
V is the volume in millilitres of sodium hydroxide solution; |
|
N is the normality of the sodium hydroxide solution; and |
|
m is the mass, in grams, of the test sample. |
|
ANNEX L |
|
DETERMINATION OF COLOUR GRADER NUMBER |
|
L.1 Apparatus |
|
L.1.1 Kent Jones apparatus |
|
L.1.2 Stop clock |
|
L.2 Procedure |
|
Weigh 30 g of sample into 250 ml beaker and add 50 ml of distilled water. Start the clock and mixing simultaneously. The mixing is done for 45 seconds only to achieve a smooth paste, which is then poured into a dead cell held at an angle of 45°. Place the cell in the holder and clamp in position. Check the zero at this point by pressing the Galvanometer key and make sure there is no movement of the spot. The cell holder is now lowered and the Galvanometer key control is pressed. The spot is returned to zero using the large control still holding the Galvanometer key down. This will have moved the circular scale from the working reference that it was set at to set zero. The reading on this scale is now the colour grade result in K.J.M. units. From the end of mixing to the point where the reading is taken should be 45 seconds making 90 seconds total. This timing is very important. |
|
ANNEX M |
|
SIEVING TEST (GRANULARITY) |
|
Weigh 100 g of the material and transfer to a laboratory sifter with a sieve of appropriate aperture size for 4 minutes. Brush the upper surface of the sieve and sieve again for 1 minute. Weigh the tails on the sieve, and report the result as percentage by mass. |

The foaming, if any, shall dissipate rapidly. After the well-mixed and reduced paint has been stored for seventy-two hours at 25 ± 5°C, it shall show no signs of instability of the emulsion. The paint shall readily re-mix to a smooth uniform state suitable for roller, brush or spray application.
2.8 pH Value
The pH value of the material when determined by a suitable glass electrode system shall be between 8.0 and 8.5.
2.9 Shelf-life
The paint, when stored at a temperature between 18°C and 30°C in shade and in fully sealed containers as delivered by the manufacturer, shall meet all the requirements of this Standard up to at least nine months from the indicated date of manufacture.
2.10 Temperature Stability
The paint when put into a 400 ml glass jar with ground-in cover, to about three quarters full, and kept fully closed in a suitable oven at a temperature of 40 ± 2°C for one month or 60 ± °C for forty-eight hours shall not develop an offensive odour and shall still comply with the requirements of 2.7, 2.13 and 2.14.
2.11 Mass in Kgs/Litre
The mass in kgs/litre of the material when tested in accordance with ZS 284, Part 17, shall not differ by more than + 5% from that of the approved sample.
2.12 Resistance to Alkali
The difference between the unsealed and the sealed material shall not be appreciable when examined visually.
2.13 Application
The material shall, after recommended thinning, be suitable for application by brush, spray or roller. The first coat shall work satisfactorily and during the application of the second coat, the paint shall brush, spray or work easily, flow, spread and join well. It shall show no floating, film coarseness or any other undesirable film characteristic in the wet or dry film.
2.14 Re-coating Properties
When three successive coats of paint, after suitable thinning with water, are applied under normal conditions on dry asbestos cement panel, at an interval of two hours between coats, by brushing, roller-coating or spraying at a spreading rate of approximately 12 square metres per litre, there shall be no lifting of the under-lying coats. The paint system shall not exhibit colour separation, sagging, pitting, flaking or cracking. No difficulty shall be experienced with the application of the successive coats by brushing, spraying or with the roller. The brush marks produced during brush application shall not be more pronounced than those on the first coat.
2.15 Drying Properties
Apply a coat of paint on a glass panel giving a wet film thickness of approximately 75 lm. The paint shall be surface dry at the end of twenty minutes and shall dry to a suitable condition for re-coating within two hours.
2.16 Specular Gloss at 85° (sheen)
Apply a coal of paint by means of a spreading device (e. g. doctor’s blade) on a glass panel.
2.16.1 giving a wet film thickness of approximately 75 lm.
2.16.2 The dry paint shall have the 85°C specular gloss given below, relevant to the type of finish specified by the manufacturer—
(a) flat finishes: 15 max; and
(b) egg-shell finishes: 16-50.
2.17 Colour
The colour of the paint specified shall be as agreed between the purchaser and vendor.
2.18 Reflectance of White Paints
White paint shall have a daylight 45°, 0° luminous directional reflectance relative to magnesium oxide of at least 85%.
2.19 Hiding Power
A paint that has the daylight 45°, 0° luminous directional reflectance value in column 1 of the Table below shall have the corresponding dry hiding power given in column 2.

5.3 Tank Design
5.3.1 General
A tank and its ancillary equipment shall be designed in accordance with sound engineering principles, due consideration having been given to expected road conditions.
5.3.2 Capacity
5.3.2.1 The tank, which may be of the single-compartment or multi-compartment type, shall have a total-volume capacity, including a usage of between 2.5% and 5% of that capacity at 47°C of the liquid as required, and in no case shall the capacity of a compartment exceed 7,000 litres.
5.3.2.2 The maximum volumetric capacity shall not apply to heavy fuel oil. In addition, the total-volume capacity of a tank calculated on the liquid density of the product that is to be transported shall be such that when the road tank vehicle is fully loaded, its mass does not exceed the appropriate requirements of the Road Traffic Act, No. 11 of 2002 of the Laws of Zambia and the Public Roads Act, No. 12 of 2002 of the Laws of Zambia.
5.3.2.3 The volumetric quantity carried in the compartment shall be as calibrated by the Zambia Weights and Measures Agency and the usage mark sealed.
5.3.2.4 The Zambia Weights and Measures Agency shall conduct tank calibration and issue a certificate at least once a year or during the following instances—
(a) after the usage marks have been disturbed;
(b) after major repairs have been carried out on the tank;
(c) after vehicle combination changes;
(d) after any damage to the shell of the tank; or
(e) after any change of ownership.
5.3.2.5 The manhole covers shall be secured by four Zambia Weights and Measures seals, sealed diagonally for the bolted and hooked manhole types and one seal for the belted manhole type.
5.3.3 Shape
The tank may be of circular, elliptical or any other acceptable cross-section and shall be self-draining.
5.3.4 Maximum Stress Value
The maximum calculated stress value of a tank, including all stresses given in 5.3.5 to 5.3.7, shall not exceed 20% of the tensile strength of the material used for its construction.
5.3.5 Design Pressure
The design pressure shall be at least 23 kPa plus the pressure exerted by the static head of liquid in the fully loaded tank in the normal position. This shall be based on the greater of the density at 20°C of the flammable liquid for which the tank is being designed or 865kg/m3.
5.3.6 Dynamic Loading
Each tank and its components and ancillary equipment shall be designed to withstand dynamic loading in all directions and for all load configurations. The total dynamic loading shall be deduced by multiplying the static loads in question by the following acceleration factors considered individually—
(a) 2g in the direction of travel;
(b) 1g in the vertically upwards direction;
(c) 2g in the vertically downwards direction; and
(d) 1g in the transverse horizontal direction.
NOTE: For the safety factors in paragraphs (a) to (d) above, the safety devices discussed in 5.5 shall apply.
5.3.7 Additional Loads
The following additional loads shall be taken into account and, where applicable, a vector summation of all the loads under dynamic loading conditions shall be made—
(a) superimposed loads such as operating equipment, insulation, linings, hose tubes, cabinets and piping;
(b) reactions at supporting lugs and at saddles or other supports; and
(c) differential thermal expansion of dissimilar metals.
5.3.8 Distribution of Loads
The loads from supports shall be borne by bulkheads, baffles or ring stiffeners and shall be distributed as widely over the members as is practicable by using pads, gussets or other appropriate means of avoiding stress concentration.
5.3.9 Towing
For tank trailers the calculated D-value of the tow-eye and the tow-hitch shall always be less than that of the actual rating on the tow-eye. The tow-eye and the tow-hitch shall both be supplied by an approved supplier.
5.3.10 Shell, Meads, Bulkheads and Baffles
5.3.10.1 Thickness of the Shell, Heads, Bulkheads and Baffles
Thickness of the shell, the heads, and where fitted, the bulkheads and baffles shall be—
(a) such that, under dynamic loading conditions, the maximum stress value given in 5.3.4 is not exceeded; and
(b) not less than the relevant minimum given in Table 3 or 4 as appropriate and in no case, except at the knuckle-radius, shall the thickness of a tank head be less than the thickness of the shell.
NOTES:
1. The material thickness given in Tables 2 and 3 are based on a liquid density of 865 kg/m3. Where the liquid density of the flammable liquid to be conveyed in the tank exceeds 865 kg/m3, the thickness of the shell will have to be proportionally increased.
2. Where an aluminium alloy is used for the construction of a head, bulkhead, baffle or ring stiffener it shall be in the O (annealed) or stronger temper. A shell shall be constructed of material with properties at least equal to grade 5454 of ASTM B209 in the H32 or H34 tempers, or where lower tensile strength tempers are used, the minimum thickness of shell material given in Table 2 shall be proportional increased.
3. Consideration should be given to the loss of strength of an aluminium alloy in the welded condition (see 5.4.2.3).
5.3.10.2 Stiffening of Heads, Bulkheads and Baffles
Unless a proven equivalent form of stiffening is provided, the following requirement shall apply—
Heads, bulkheads and baffles for all tanks shall be dished to a depth, exclusive of any flange of at least 120 mm/m of the depth of the minor axis of the tank cross section.

(b) pressure gauge, capable of reading from – 10 kPa to + 100 kPa;
(c) pressure;
(d) air flow meter;
(e) water flow meter;
(f) exhauster;
(g) compressed air supply; and
(h) water supply.
7.5.1.2 Procedure
Fit in the normal operating positions the manhole cover, the hatch and where relevant any additional vent of the prototype.
7.5.1.2.1 Connect the exhauster, air flow meter and pressure gauge to the tank. Operate the exhauster, record the vacuum at which the vent starts to open and check normal vents for compliance with 5.5.3.1.
7.5.1.2.2 Where relevant, slowly increase the rate of exhaustion to a value corresponding to the maximum liquid discharging rate (see 6.1(j)). Check that filling and discharging vents do not allow the vacuum to exceed 7 kPa (see 5.5.3.2).
7.5.1.2.3 Disconnect the exhauster and replace it with the compressed air supply. Slowly introduce dry air and check the pressure at which the vent starts to open for compliance with 5.5.3.1, in the case of normal vents, and with 5.5.3.3(b), in the case of pressure actuated emergency vents.
7.5.1.2.4 Adjust the air flow until steady operating conditions are obtained at a pressure corresponding to the pressure claimed by the manufacturer (see 6.2). Except in the case of fusible vent record the flow rate and check for compliance with 5.5.3.4.
7.5.1.2.5 When relevant, adjust the air flow until a steady pressure of 35 kPa is obtained and check the flow rate of pressure actuated emergency vents for compliance with 5.5.3.3.
7.5.1.2.6 When relevant, adjust the rate of air flow to the maximum liquid filling rate for the tank (see 6.1 and check filling and discharging vents for compliance with 5.5.3.2).
7.5.1.2.7 Adjust the air flow to obtain a pressure in excess of 25 kPa, slowly decrease the air flow and check the pressure at which the emergency pressure vent closes for compliance with 5.5.3.3(b).
7.5.1.2.8 When relevant, connect the tank to the flow meter, pressure gauge and water supply. Adjust the flow rate to the maximum liquid filling rate for the tank (see 6.1(i) and check the filling vent for compliance with the relevant requirement of 5.5.3.2).
7.5.1.2.9 Dry the tank manhole cover and vents. Where a fusible vent is fitted remove the plug. Connect the air supply, flow meter and pressure gauge to the tank and by introducing dry air at a steady pressure of 35 kPa, verify that the total venting capacity of the emergency vents complies with 5.5.3.3(a).
7.5.1.2.10 Where a fusible vent is fitted with the plug removed and with all other vents scaled verify the accuracy of the flow rate claimed by the manufacturer (see 6.2 and 5.5.3.3(c)).
7.6 Testing of Manhole Covers (and Hatch Closures, When Fitted)
7.6.1 Drop Test
7.6.1.1 Conduct the test as follows—
(a) attach the base plate of the manhole cover, including the fill opening of the prototype (see NOTE (b) clause 1) to the end of a steel tube of such thickness that it will not distort during the test and that it has a length of 1.5 to 1.6 m and a shape such that the sealing ring of the base plate forms a liquid tight joint with the tube and with a suitable stop at the end of the tube;
(b) place the assembly in a suitable apparatus with the manhole cover at the bottom. Fill the tube with water to a depth of 0.9 m to 1.0 m;
(c) raise the assembly vertically to height of 1.45m to 1.55m (measured from its lowest point); and
(d) allow the tube and fitted manhole cover to fall freely through a distance of 1.20m – 1.21m and arrest the fall abruptly by means of the stop at the open end of the tube.
7.6.1.2 Consider the manhole cover (and hatch closure, if fitted) to have passed the test if the assembly remains liquid-tight throughout, except that sight is permissible on impact, provided that the leak stops immediately thereafter.
7.6.2 Pressure Test
Conduct the test as follows—
(a) fit each manhole cover including the fill opening with a safety device that prevents the cover from opening fully when internal pressure is present;
(b) secure each cover with fastening that will prevent opening of the covers as a result of vibration under normal conditions of transportation or of shock impact due to a rollover accident on the roadway or shoulder, provided that the area is not struck by a substantial obstacle; and
(c) mark each cover permanently by stamping or other means with—

NOTE: The relative density is represented by the ratio of the mass of LPG at 15°C to that of water at 4°C |
5.2 Filling by Mass
The maximum mass, M (in kilograms), of liquid that may be introduced into a tank may be calculated from the following formula—
M = C x D
Where—
C = water capacity of the tank, kg; and
D = filling ratio.
5.3 Filling by Volume
5.3.1 The maximum volume (at a particular temperature, T) of liquid, VT, (expressed as a percentage of total tank capacity) that may be introduced into a tank may be calculated from the following formula, the temperature of the LPG being obtained by means of a thermometer placed in a thermometer pocket installed in the tank—
Where—
D = filling ratio
G = relative density of the LPG at 20°/20°C
F = liquid volume correction factor (see IP 250 and consider the relative density at 20°/20°C to be the density at 20°C);
T = temperature of liquid LPG in the tank, °C.
5.3.2 The actual maximum volume of LPG that may be introduced into the tank is obtained by multiplying the water capacity of the tank by VT/100.

NOTES TO PURCHASERS
A.1 Before the purchaser orders cables produced to this specification, it is suggested that the following points be considered:
A.1.1 Identification of cores
The identification of cores, particularly in power cables, should preferably be done by colour coding.
Identification by numbers is also acceptable. The neutral must always be black or carry the number -0-, or both. Particular care should be taken to select the correct colours when a three-core or four-core cable intended for use on single-phase circuits is being ordered.
A.1.2 Current rating
The current rating of the cable and the applicable rating factors for a particular installation should be ascertained from the cable manufacturer. This information is also given in ZS 772.
A.1.3 Type of cable
Careful consideration should be given to the type of cable to be used for a particular installation. Alternatives such as copper or aluminium conductors, conventional PVC insulation and sheathing flame-retardant, low smoke emission, halogen-free cables, armoured or unarmoured cables, should be considered.
A.2 it is recommended that the following requirements be specified in invitations to tender and in each order or contract:
(a) the maximum permissible operating voltage;
(b) the conditions of service of the cable;
(c) the conductor material (copper, tinned copper or aluminium) and the type of conductor;
(d) the type of insulation material;
(e) colour coding or numbering of cores;
(f) the type of bedding material;
(g) whether the cable is to be armoured;
(h) if the cable is to be armoured, the material of the armour wires;
(i) in the case of a cable with steel wire armour, whether an earth continuity conductor (ECC) is required;
(j) the type of material of the sheath;
(k) in the case of a cable with a metallic sheath, whether the metal is to be lead or lead alloy of type (see Annex B of EN 12548:1999);
(l) whether fire retardant properties are required;
(m) in the case of cables packed on wooden drums, whether the wood of the drum is to be resistant to biological attack; and
(n) whether the number of cores and the cross-sectional area are to be indicated on the cable.
A.3ZS IEC 60332-3 denotes four optional categories, namely A, B, C and D. Current research indicates that cables that satisfy the requirements for Category C, comply with the flame propagation requirements for steel wire armoured cables in accordance with both national and international standards.
ANNEX B

Armour wire shall be applied with an acceptable lay, without any appreciable space between adjacent wires, and there shall be no crossed, riding or protruding wire. Joints in the wire shall be made to an acceptable standard of workmanship without sharp edges or protruding points, and multiple joints shall be acceptably staggered.
(c) type of armour wire:
(i) for single-core cables, the armour shall be of non-magnetic wire; and
(ii) for multicore cables the armour shall be of galvanised steel wire, except as allowed in paragraph (d).
(d) earth continuity conductor: when an improved conductivity in the earth continuity circuit of steel wire armoured multicore cables is required, an appropriate number of steel armour wires may be replaced by tinned hard-drawn copper wires of the same nominal diameter. The copper wires shall comply with the relevant requirements of Zambian Standard ZS 756-1.
The following requirements shall apply:
(i) the copper wires shall be of diameter equal to that of the armour, and of number as stated in table 5, appropriate to the cross-sectional area of the conductor; and
(ii) the copper wires shall be grouped together and shall not be distributed amongst the armour wires.

4. 2.5.2.3Thickness:
When the thickness of the sheath is determined in accordance with Zambian Standard ZS IEC 60811-1-1, it shall be at least equal to the value obtained from the following formula:
t = 0.033 D + 0.7 mm (minimum 1.2 mm)
where—
tis the thickness of sheath, in millimeters; and
D is the calculated diameter over the core or over the laid-up and filled cores, in millimeters.
NOTE Round off the calculated values of the thickness t to the nearest 0.1 mm
4. 2.5.3 Bedding of armoured cable
4. 2.5.3.1Material: Bedding shall consist of a smooth surfaced circular layer of material that complies with the requirements of ZS 756-5 (see table 12). The bedding shall not adhere to the underlying cores or binder.
4. 2.5.3.2 Thickness:
(a) the nominal and minimum thickness of the bedding shall be as given in table 10 or 11, as relevant; and
(b) when the average thickness of the bedding is determined in accordance with ZS IEC
60811-1-1, it shall be at least equal to the nominal value, and the minimum thickness at any point may be less than the nominal value, except provided that the difference shall not exceed 0.1 mm + 15 % of the nominal value.
4. 2.5.4 Armour
When so required, the cable shall be armoured, and the armouring shall comply with the following:
(a) Material: Armour shall consist of round wire of galvanised steel or aluminium, as required, and shall comply with ZS 756-6.
(b) Armouring: The nominal diameter of armour wire shall be as given in table 10 or 11, as relevant. Armour wire shall be applied with an acceptable lay, without any appreciable space between adjacent wires, and there shall be no crossed, riding or protruding wire. Joints in the wire shall be made to an acceptable standard of workmanship without sharp edges or protruding points, and multiple joints shall be acceptably staggered.
(c) Type of armour wire:
(i) For single-core cables, the armour shall be of non-magnetic wire.
(ii) For multicore cables the armour shall be of galvanised steel wire, except as allowed for in paragraph(d).
(d) Earth continuity conductor: When an improved conductivity in the earth continuity circuit of steel wire armoured multicore cables is required, an appropriate number of steel wires may be replaced by tinned hard-drawn copper wires of the same nominal diameter. The copper wires shall comply with the relevant requirements of ZS 756.
The following requirements shall apply:
(i) The copper wires shall be of diameter equal to that of the armour, and of number as given in table 5, appropriate to the cross-sectional area of the conductor.
(ii) The copper wires shall be grouped together and shall not be distributed amongst the armour wires. Where eight or more armour wires are replaced by copper wires, the copper wires shall be arranged in two diametrically opposed groups to allow for a more even distribution of the clamping forces when a mechanical gland is used to terminate the cable.

Note 1 In column 3 of this table, a code letter is given that identifies the tests as suitable for use as routine tests (R), sample tests (S) or type tests (T), but compliance with the requirements of the specification may only be fully determined from the results of tests carried out on samples of completed cable(s), using all the test methods given and a sampling procedure agreed upon. During production control, a manufacturer may use any tests considered necessary to ensure compliance with the specification but, in the case of a dispute, only the appropriate standard test methods may be used.Note 2 In the administration of the standardisation mark scheme, the frequency of testing required and the tests to be used are the subject of a separate agreement between the Authority administering this standard and the permit holder.
5.2 Conditions of Test
5. 2.1 All tests are to be carried out at ambient temperature and pressure, unless otherwise stated in the test method.
5.2.2 Unless otherwise required in the test method, the frequency of the alternating test voltage used shall be approximately 50 Hz, and the waveform shall be substantially sinusoidal.

|
A.1.6. The sample containers shall be of a size that they are almost completely filled by the sample. |
|
A.1.7. Each sample container shall be sealed air-tight with a suitable stopper after filling, and marked with full details of sampling, the date of sampling and the year of manufacture of the material. |
|
A. 2. Scale of Sampling |
|
A.2.1. Lot |
|
All the cartons in a single consignment of the material drawn from a single batch of manufacture shall constitute a lot. If a consignment is declared to consist of different batches of manufacture, the batches shall be marked separately and the groups of cartons in each batch shall constitute separate lots. |
|
Samples shall be tested from each lot for ascertaining conformity of the material to the requirements of the specification. |
|
A.2.2. The number of cartons (n) to be chosen from the lot shall depend on the size of the lot (N) and shall be in accordance with column 1 and 2 of Table A. 1. |
|
A.2.3. The cartons and containers to be selected for sampling shall be chosen at random from the lot and for this purpose random number tables shall be used. In case the tables are not available, the following procedure shall be adopted— |
|
Starting from any container, count them as 1, 2, 3 etc. up to r and so on, in a systematic manner, where r is the integral part of N/n. Every rth container thus counted shall be withdrawn from the lot. |

|
2.2. All standards are subject to revision and since any reference to a standard is considered to be a reference to the latest edition of that standard, parties to agreements based on this standard are encouraged to ensure the use of the most recent editions of the standards indicated above. |
|
3. DEFINITIONS |
|
In this standard, the definitions given in ZS 325 and the following shall apply— |
|
“blended fertiliser” means a product obtained by physical mixing of different fertiliser ingredients or stock materials and containing more than one of the major plant nutrients, namely, nitrogen, phosphorous and potassium and/or are simple mixtures of more than one fertiliser in which chemical interaction does not take place and they may be mixed in different proportions; |
|
“compatibility” means a non-chemical reaction of two or more fertiliser ingredients (materials) when mixed; |
|
“crop” means a plant for which a particular blended fertiliser shall be used to provide nutrients in a field for a particular crop season; |
|
“filler” means a substance added to fertiliser materials to provide bulk, prevent caking, or serve some purpose except providing essential plant nutrients; |
|
“ingredients (source)” means materials, usually straight fertilisers, used as sources of particular nutrients in a blended fertiliser (See Annex A); |
|
“segregation” means a non-uniformity of composition throughout a blended fertiliser lot; and |
|
“soil testing” means a process of taking a representative sample from a field and testing it for available nutrients and other properties, for example, pH. |
|
4. REQUIREMENTS |
|
4.1. General |
|
(a) Blended fertilisers shall be in the form of powder, crystals or granules and shall be non-caking, free flowing and free from visible impurities. |
|
(b) The blended fertiliser shall be properly mixed so that the ingredients are uniformly distributed and there is no segregation of the ingredients. |
|
(c) There shall be very negligible dust or fine particles settling at the bottom of the blended fertiliser (bags or bulk). |
|
4.2. Particle size |
|
(a) The size range as well as the particle size distribution of the different ingredients of the blended fertilisers shall be compatible. |
|
(b) The particle size (sieve analysis) of blended fertilisers shall be such that a minimum of 90% shall pass through 1.5 mm – 5.0 mm sieve and retained on 1.00 mm sieve for standard products. |
|
4.3. Chemical requirements |
|
(a) General |
|
Blended fertilisers shall be essentially a mixture of chemically compatible (See Annex B) and physically homogenous constituents. |
|
(b) Nutrient composition |
|
(i) If a particular blended fertiliser has the same specification as any of the compound fertilisers in ZS 431 (Compound Fertilisers – Specification), it shall be required to meet the analysis of that particular compound fertiliser. Other blended fertilisers not contained in ZS 431 shall conform to the labelled nutrient composition upon laboratory testing. |
|
(ii) Every ingredient (source) of the declared nutrients in the blended fertilisers shall be readily available to the particular crop for the particular crop season and not just past the period when the crop needs the nutrients. This may require that both the farmer and the supplier are aware of the soil characteristics through soil testing (any other factor in the soil or weather conditions which may affect the fertiliser performance) for which the particular blended fertiliser is being mixed so that good results are realised. This also means that the crop shall not show adverse deficiency of any nutrient of an efficiently and effectively applied blended fertiliser. |
|
(iii) Elemental nutrient sources or ingredients if used shall also be readily available to the crop as stated in (ii). Non-soluble elemental sources shall not be used in blended fertilisers. |
|
(iv) If a micronutrient source in powder form is added as a coat on to the surface of the blend granules or crystals, an effective binder or coating agent (to enhance adherence) shall be used so that there is no segregation of the micronutrient onto the bottom of the blended fertiliser. |
|
Note: Only micronutrient sources shall be in powder (fine) form. |
|
(v) The filler used in the blended fertiliser shall by no means substitute any of the declared nutrients. |
|
(vi) The composition nutrients of blended fertiliser shall be declared in terms of total nitrogen, total phosphorous or water-soluble phosphorous and water-soluble potassium in accordance with ZS 324: Parts 3 or 13, ZS 324: Parts 2 or 12 and ZS 324: Part 17 respectively. The permissible limit of variation for these nutrients shall be as follows— |
|
The actual percentage nutrient content of each declared nutrient shall be within ± 2% of the fertiliser when determined in accordance with the declared content; and |
|
The sum of actual percentage nutrient content of all declared nutrients shall be within ± 2.5% unit of the sum of the declared contents. |
|
5. SAMPLING |
|
Sampling shall be carried out in accordance with ZS 356: Part 1. |
|
6. PACKAGING |
|
6.1. Individual container |
|
(a) Blended fertilisers shall be packaged in suitable, clean, sound and moisture proof containers or packages. |
|
(b) Suitable packaging materials include polypropylene, and high density polyethylene bags with an inner loose tubular liner polyethylene film. |
|
6.2. Bulk container |
|
The fertiliser may also be supplied in bulk. Where it is supplied in bulk, the bulk container shall be sound, clean, dry and capable of protecting the product from adventitious contamination and moisture absorption. |
|
7. LABELLING AND MARKING |
|
7.1. Individual container |
|
(a) Each container of blended fertilisers shall be labelled indelibly with the following particulars— |
|
(i) name of the fertiliser; |
|
(ii) the word “BLENDED”, conveniently in brackets; |
|
(iii) the nominal percentage composition of the mixture as N: P2O5: K2O and trace elements in elemental form; |

|
(vi) name and address of the manufacturer or supplier; and |
|
(vii) any other marking requirements laid down by the purchaser. |
|
(b) Each container should carry relevant safety and environmental effect markings. |
|
7.2. Bulk container |
|
Where the fertiliser is supplied in bulk, the labelling information shall accompany the delivery note. |
|
8. TEST REPORT |
|
8.1. The test report for the particular batch or lot of the blended fertiliser shall declare the source or ingredients and the proportions in which they were mixed for the particular nutrient composition stated. |
|
8.2. If a binder or coating agent is used for the adherence of the micronutrients onto the fertiliser granules or crystals, it shall also be declared (name and quantity) in the test report. |
|
8.3. Any filler and its proportion, used in the blended fertiliser, shall be declared in the test report. |
|

(Normative)
HANDLING AND PACKAGING
|
A. 1. Handling and Packaging |
|
Penetration grade bitumens are normally supplied hot in bulk by road tanker, and handling procedures should be in accordance with the latest revision of the Institute of Petroleum Model Code of Safe Practice, Part 11, Bitumen Safety Code or the Bitumen Safety Handbook published by SABITA. Penetration grade bitumen may also be supplied in sealed drums and suppliers’ recommendations should be sought with regard to appropriate handling procedures. The condition of the containers and road tank vehicles into which the penetration grade bitumen is filled shall be such as not to be detrimental to the quality of the product during normal transportation and storage. The drums shall be sealed and shall conform to the Petroleum Act, Chapter 435 of the Laws of Zambia. |
APPENDIX B
(Normative)
SAMPLING AND TESTING
|
B. 1. Sampling Locations |
|
B. 1.1. For the purposes of this Zambian Standard all sampling shall be carried out in accordance with the relevant procedures of ZS 396. In addition, if it is desired to take a sample of penetration grade bitumen it may be taken from any of the following locations— |
|
(a) from the tanker, in the case of bulk delivery by road, immediately before discharge; |
|
(b) from the storage tank (or the feed pipe to the mixer) of a manufacturer of mixtures of bitumen and mineral matter, immediately before mixing; or |
|
(c) from the tank of a binder distributor used for surface dressing immediately before spraying. |
|
B. 2. Sampling Procedures |
|
When sampling penetration grade bitumen it is essential that the purchaser obtain a sample of not less than 5 kg, which represents the material supplied. The sample shall be immediately divided into three approximately equal sub-samples that shall be placed in clean and dry metal containers capable of being securely closed. Each sub-sample shall be clearly labelled with the names of the supplier and purchaser, details of the grades of penetration grade bitumen, time and date of sampling and identification of the sampling location. Samples should be retained for at least three months. |
|
It is essential that the purchaser use only one of the sub-samples for the purchaser’s own tests, the remaining two sub-samples being retained by the purchaser in case of dispute. |
|
Note: |
|
1. It is recommended that routine checking of penetration grade bitumen should be based on the penetration test and softening point in the case of grades covered in Table 1. Experience shows that checking other specified properties is only necessary when there are reasons to suspect the quality of the material. |
|
2. To ensure valid comparison between the test results of the purchaser and supplier, it is essential that both test the material within 7 days of taking the sample. |

1 All cutbacks shall be blended from pen 80 – 100 grade bitumen. |
|
2 Cutback bitumen shall be homogenous, free from visible water and will not foam when heated to application temperature. |
|
3 IP 113 and ASTM D 1310 are acceptable methods to be used to determine the flash point although cognisance should be taken of the diluent used to make the cutback bitumen as this will affect the accuracy of results obtained. |

HANDLING AND PACKAGING
|
A. 1. Handling and Packaging |
|
Cutback bitumens are normally supplied hot in bulk by road tanker. Handling procedures should be in accordance with the latest revision of the Institute of Petroleum Model Code of Safe Practice, Part 11, Bitumen Safety Code or the Bitumen Safety Handbook published by SABITA. Uncontrolled heating of cutback bitumens can lead to loss of volatile diluent and consequent non-compliance with the specification. |
|
Cutback bitumen may also be supplied in sealed drums and suppliers’ recommendations should be sought with regard to appropriate handling procedures. The condition of the containers and road tank vehicles into which the cutback bitumen is filled shall be such as not to be detrimental to the quality and quantity of the product during normal transportation and storage. The drums shall be sealed and shall conform to the Petroleum Act, Chapter 435 of the Laws of Zambia. |
APPENDIX B
(Normative)
SAMPLING AND TESTING
|
B.1. Sampling Locations |
|
B.1.1. For the purposes of this Zambian Standard all sampling shall be carried out in accordance with the relevant procedures of ZS 396. In addition, if it is desired to take a sample of cutback bitumen it may be taken from any of the following locations— |
|
(a) from the tanker, in the case of bulk delivery by road, immediately before discharge; |
|
(b) from the storage tank (or the feed pipe to the mixer) of a manufacturer of mixtures of bitumen and mineral matter, immediately before mixing; or |
|
(c) from the tank of a binder distributor used for surface dressing immediately before spraying. |
|
B.1.2. The procedures involved in handling the binder for surface dressing may lead to some loss of volatile constituents from the cutback bitumen without necessarily impairing the performance of the surface dressing. Where a sample of cutback bitumen has been taken from one of the locations listed in B.1.1 it shall be assumed that the viscosity requirements of the standard have been complied with provided the viscosity is within the following limits— |
|
Saybolt – Furol Viscosity Limits |
|
MC-30 – Furol Viscosity at 25°C – 75 to 150 sec |
|
MC-70 – Furol Viscosity at 50°C – 60 to 120 sec |
|
MC-800 – Furol Viscosity at 82.2°C – 100 to 200 sec |
|
MC-3000 – Furol Viscosity at 82.2°C – 300 to 600 sec |
|
B.2. Sampling Procedures |
|
When sampling cutback bitumen it is essential that the purchaser obtain a sample of not less than 5 kg, which represents the material supplied. The sample shall be immediately divided into three approximately equal sub-samples that shall be placed in clean and dry metal containers capable of being securely closed. Each sub-sample shall be clearly labelled with the names of the supplier and purchaser, details of the grades of cutback bitumen, time and date of sampling and identification of the sampling location. Samples should be retained for at least three months. |
|
It is essential that the purchaser use only one of the sub-samples for the purchaser’s own tests, with the remaining two sub-samples being retained by the purchaser in case of dispute. |
|
Note: |
|
1. It is recommended that routine checking of cutback bitumen should be based on the viscosity test in the case of grades covered in Table 1. Experience shows that checking other specified properties is only necessary when there are reasons to suspect the quality of the material. |
|
2. To ensure valid comparison between the test results of the purchaser and supplier, it is essential that both test samples are of the same age. |
