This standard describes the reference method used for type testing and in cases of dispute, for the determination of the shape index of coarse aggregates. For other purposes, in particular factory production control, other methods may be used provided an appropriate working relationship with the reference method has been established. The test method specified inThis European Standard is applicable to particle size fractions di/Di where Di 63 mm and di 4 mm.
