This is a reference method, which is designed with an appropriate precision level aimed at enabling validation of any quantity declaration made.This document applies to material that is in solid form, but not in block form to be sold by dimension, and which exceeds the particle size restriction in EN 12580 [1] and where the declared nominal particle size is greater than 60 mm. This method is applicable for products where a mass fraction of less than 10% of material is retained on the 100 mm fall controll
