标准范围
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.
