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 (Si02) 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 alumínate in calcium alumínate 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, Si02, A1203, Fe203 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 . Si02 and 2CaO . Si02), the remainder consisting of aluminium and iron containing clinker phases and other compounds. The ratio by mass (Ca0)/(Si02) 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)

The ratio by mass (CaO + MgO)/(SiOz) shall exceed 1.0

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 alumínate compounds. These compounds are similar to those which are formed in the hardening of hydraulic materials. Pozzolanas shall consist essentially of reactive Si02 and Al203. The remainder contains Fe203 and other oxides. The proportion of reactive Ca0³⁾ is negligible. The reactive Si02 content shall be not less than 25 % by mass.

Pozzolanic materials shall be correctly prepared, i.e. selected, homogenized, 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 (Si02) and aluminium oxide (A1203). The remainder contains iron oxide (Fe203) 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 (Si02) and aluminium oxide (A1203). The remainder contains iron oxide (Fe203) and other compounds. The proportion of reactive calcium oxide shall not be less than 10.0%bymass. 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 (503) 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 (S03) 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 (CaC03) content calculated from the calcium oxide content shall be at least 75 % by mass.

(b) The clay content, de/ermined 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 ayailable 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 ,'/2H 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.

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.

Table 5 - Required values Pk and CR

	Mechanical requirements
	Early and standard strength	Standard strength	Physical and chemical requirements
	(Lower limit)	(Upper limit)
The percentage Pk on which the characteristic value is based	5%	10%
Allowable of probability acceptable CR	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 totalityof 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.

Note - Values given in this table are valid for CR = 5 %.
" Values of kA valid for intermediate values of n may also be used.

9.2.2.3 Inspection by attributes

The number CD of test results outside the characteristic value shall be counted and compared with an acceptable number CA, calculated from the number n of auto-control test results and the percentile Pk as specified in Table 7.

Conformity is verified when equation (3) is satisfied:

CD ^CA (3)

The value of CA depends on the percentile Pk on which the characteristic value is based, on the allowable probability of acceptance CR and on a number n of the test results. Values of CA are listed in Table 7.

‘ 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. The limiting quantities of the main constituents specified in Table 1 are reference values to be met by the average composition calculated from the spot samples taken in the control period. For single results, maximum deviations of -2 at the lower and +2 at the higher reference value are allowed. Suitable procedures during production and appropriate verification methods to ensure conformity to this requirement shall be applied and documented.

9.4 Conformity criteria for properties of the cement constituents

The cement constituents shall meet the requirements specified in clause 5. Suitable procedures during production to ensure conformity with this requirement shall be applied and documented.

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.

ZA.2 Procedure for the attestation of conformity of products

The system of attestation of conformity for the 27 common cement products indicated in table ZA. 1 is shown in table ZA.2 for the indicated intended use(s), in accordance with the Commission Decision of 14 July 1997 (97/555/EC) published in the Official Journal of the European Communities and given in annex 3 of the Mandate for the product family “Cements”.

Table ZA.2 System of attestation of conformity

Product(s)	Intended use(s)	Level(s) or class(es)	Attestation of conformity system(s)
Common cements, including:	Preparation of concrete, mortar, grout and other mixes for construction and for the manufacture of construction products		1 +

System 1 +: See annex III Section 2 point (i) of Directive 89/106/EEC, with audit-testing of samples taken at the factory

The attestation of conformity to the specifications in EN 197-1 shall be based on clause 9 ofEN

197-1 and on evaluation of conformity³⁾ which shall be in accordance with EN 197-2. Clause 8 of EN 197-2 does not apply since it is superseded for CE marking purposes by the rules given in clauses ZA.3 and

ZA.4. Clause 9 of EN 197-2, giving rules relating to Dispatching Centres, is not part of the procedure of attestation of conformity for the affixing of the CE marking under the CPO. However, Member States, within their market surveillance obligations, must ensure that CE marking is correctly used (Article 15.1 oftheCPO). Clause9ofEN 197-2 should be used for the corresponding national provisions concerning Dispatching Centres.

³⁾ This term corresponds to the establishment of conformity that is mentioned in article 13.2 of the CPO

ZA.3 EC certificate of conformity and EC declaration of conformity

When compliance with the system of attestation of conformity is achieved in accordance with clause 7 of EN 197-2, the certification body shall draw up a certificate of conformity (EC certificate of conformity) with the information indicated below. This EC certificate of conformity entitles the manufacturer to affix the CE marking, as described in ZA.4.

The EC certificate of conformity shall include the following information:

- Name and address of the certification body,

- Name and address of the manufacturer, or his authorised representative established in the EEA, and place of production,

- Description of the product (the standard designation of the cement according to EN

197-1 and any additional identification required),

- Provisions to which the product conforms (annex ZA of EN 197-1, with conformity established according to EN 197-2 as given in annex ZA of EN 197-1),

- Particular conditions applicable to the use of the product (none as regards conformity),

- The certificate’s number,

- Conditions and period of validity of the certificate, where applicable,

- Name of, and position held by, the person empowered to sign the certificate.

In addition, for each product covered by an EC certificate of conformity, the manufacturer shall draw up a declaration of conformity (EC declaration of conformity) including the following information:

- Name and address of the manufacturer, or his authorised representative established in the EEA,

- Number of the attached EC certificate of conformity,

- Name of, and position held by, the person empowered to sign the declaration on behalf of the manufacturer or of his authorised representative.

Both documents must be presentèd in the official language or languages of the Member State of the EU in which the product is to be used.

(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.

<FT:Calibri,SN>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.

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

(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

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.

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—

<PS:"QT-TTI"> (a) from the tanker, in the case of bulk delivery by road, immediately before discharge;

<PS:"QT-TTI"> (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

<PS:"QT-TTI"> (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.
