scope:

This document specifies two methods for the determination of the particle size distribution of liming materials. Method A (the dry sieving method) is applicable to all liming materials except wet and paste-like products.

Method A is not applicable if blinding, caking, electrostatic charges or agglomeration occur after drying.

Method B (the wet sieving method) is applicable to products which are susceptible to blinding, caking, electrostatic charges or agglomeration after drying. Method B can be used to determine the primary particle size distribution of granulated products. Method B is not applicable to burnt lime and liming materials containing water-soluble constituents
