Tests for mechanical and physical properties of aggregates - Determination of the resistance to wear (micro-Deval) Ingestion-build-61878 as defined in Annex A

as defined in Annex A of IEC 61753-1

With some necessary modifications and adjustments

Unless one of the alternative heating regimes is specifically required

The names of the tests have been revised to the “extreme” and “normal” pressure surge tests

Preliminary experiments might be necessary to determine whether these conditions are met

Tests for mechanical and physical properties of aggregates - Determination of the resistance to wear (micro-Deval) Ingestion-build-61878 as defined in Annex A1 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
