适用范围：This standard describes the reference method used for type testing and in cases of dispute, for thedetermination of the shape index of coarse aggregates. For other purposes, in particular factory productioncontrol, other methods may be used provided an appropriate working relationship with the reference method hasbeen established.The test method specified in this European Standard is applicable to particle size fractions di/Di where Di≤ 63 mm and di ≥ 4 mm.
