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.
