Tests for geometrical properties of aggregates - Assessment of fines. Sand equivalent test Ingestion-build-81500 and recommendations for safe working1 Scope This European Standard describes the reference method used for type testing and in case of dispute for the determination of the sand equivalent value of 0 2 mm fraction (for 0 4 mm, see Annex A) in fine aggregates or all in aggregates. 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.
