Annex A (informative) - Example of a test data sheet used
                        for determining the shape index of
                        coarse aggregate

This standard describes the reference method used for type testing 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 in this European Standard is applicable to particle size fractions di/Di where Di ≤ 63 mm and di ≥ 4 mm.
