Tests for mechanical and physical properties of aggregates - Determination of the resistance to wear (micro-Deval) Ingestion-build-46800 use of IG-541 systems1 Scope This European Standard describes 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). For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the reference method has been established. The sample is normally tested in a wet
