This International Standard specifies two alternative methods for determining hygroscopic sorption properties of porous building materials and products:

a)    using desiccators and weighing cups (desiccator method);

b)    using a climatic chamber (climatic chamber method).

The desiccator method is the reference method.

This International Standard does not specify the method for sampling.

The methods specified in this International Standard can be used to determine the moisture content of a sample in equilibrium with air at a specific temperature and humidity.

This document specifies the reference method, used for type testing and in case of dispute, for the determination of the percentages of crushed particles, totally crushed particles and totally rounded particles in a sample of natural coarse aggregate or all-in aggregate. Other methods can be used for other purposes, such as factory production control, provided that an appropriate working relationship with the reference method has been established.

NOTE 1        Examples of advanced test methods can be found in the Bibliography.

This document applies to gravel or to a mixture of natural coarse aggregates containing gravel. The test method specified is applicable to particle sizes between 4 mm and 63 mm.

NOTE 2        For coarse aggregate between 4 mm and 20 mm, the percentages of crushed surfaces are linked to the flow coefficient and can therefore be used in association with the test method specified in EN 933-6.

Subclause 7.1 specifies the procedure for test portions consisting of one particle size fraction and Subclause 7.2 specifies the procedure for test portions consisting of two or more particle size fractions.

Guidance for estimated mass of the test portion is given in informative Annex A.

Examples of application of the test procedure and an example of a test data sheet are given in informative Annexes B and C.

This document specifies the reference method used for type testing and in cases of dispute for the determination of the particle density of filler by means of a pyknometer. For other purposes, in particular factory production control, other methods can be used provided that an appropriate working relationship with the reference method has been established.

NOTE            Methods for determination of particle density of aggregates are specified in EN 1097‑6.

Annexes are included that specify the procedures for calibration of the pyknometer (Annex A) and determination of the density of the liquid used to determine the particle density of the filler (Annex B).

Annex C (informative) contains precision data.

WARNING – The use of this part of EN 1097 can involve hazardous materials, operations and equipment (such as liquids, dust, noise and heavy lifts). It does not purport to address all of the safety or environmental problems associated with its use. It is the responsibility of users of this document to take appropriate measures to ensure the safety and health of personnel and the environment prior to application of the standard, and fulfil statutory and regulatory requirements for this purpose.

This document specifies the reference method used for type testing, and in case of dispute, for determining the flow coefficient of coarse and fine aggregates. Other methods can be used for other purposes, such as factory production control, provided that an appropriate working relationship with the reference method has been established. Examples of advanced test methods can be found in the Bibliography.

This document applies to coarse aggregate of sizes between 4 mm and 20 mm and to fine aggregate of size up to 2 mm.

NOTE 1        For coarse aggregates between 4 mm and 20 mm, the flow coefficient is linked with the percentage of crushed or broken surfaces of an aggregate and can therefore be used in association with the method specified in EN 933–5. Shape and surface texture characteristics also influence the result.

NOTE 2        Experience of this test has been generally limited to natural aggregates.

Examples of test data sheets are given in informative Annexes A and C.

Annex B (informative) contains precision data.

WARNING – The use of this part of EN 933 can involve hazardous materials, operations and equipment (such as dust, noise and heavy lifts). It does not purport to address all of the safety or environmental problems associated with its use.
