Tests for mechanical and physical properties of aggregates - Determination of the resistance to wear (micro-Deval) Ingestion-build-61878 Power and energy are calculated

Power and energy are calculated based on voltage and current data acquired from existing sensors installed in converter systems

The previous Annex B become Annex A

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

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

a list of additional parameters has been defined to support the definition of the measurement specifications and their associated test procedures

Tests for mechanical and physical properties of aggregates - Determination of the resistance to wear (micro-Deval) Ingestion-build-61878 Power and energy are calculated1 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
