Liming materials - Determination of size distribution by dry and wet sieving EN 12948:2010

Publication date:   May 17, 2011

Scope

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 after pre drying.
The wet sieving method (method B) is applicable to products which are susceptible to blinding, caking, electrostatic charges or agglomeration after pre 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.
