Tests for geometrical properties of aggregates - Determination of particle shape. Shape index Ingestion-build-79769 recommendations about how to applyThis European Standard specifies a method for the determination of the shape index of coarse aggregates. It applies to aggregates of natural or artificial origin, including lightweight aggregates. The test method specified in this standard is applicable to particle size fraction di Di, where Di is less than or equal to 63 mm and di is greater than or equal to 4 mm.
