This document specifies the reference method used for type testing and in case of dispute, for determining the resistance to wear of coarse aggregates (main text) and aggregates for railway ballast (Annex A). Other methods can be used for other purposes, such as factory production control, provided that an appropriate working relationship with the relevant reference method has been established. This document applies to natural, manufactured or recycled aggregates. The reference test is performed with the addition of water. Annex B gives details of how the test can be performed without the addition of water. Annex C specifies the test performed with alternative narrow size fractions. Annexes D and E specify methods for determining the wear of fine aggregates. Precision data are given in Annex F. Annex A is normative and Annexes B, C, D, E and F are informative.
