1 Scope
This European Standard specifies a method for the determination of shell content of coarse aggregates. It applies to gravel or mixed aggregate containing
gravel.
The test method specified in this part of this European Standard is applicable to
particle size fractions di/Di where Di ≤ 63 mm and di ≥ 4 mm.
NOTE For aggregate sizes with D > 63 mm and/or d <4 mm the test may be carried out on particle size fractions di/Di where Dii ≤ 63 mm and di ≥ 4 mm.
