NBN EN 12948:2002

This European Standard specifies two methods for the determination of the particle size distribution of liming materials.
The dry sieving method (method A) 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 on predrying.
The wet sieving method (method B) is applicable to products which are susceptible to blinding, caking, electrostatic charges or agglomeration on predrying.
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.
