Scope

This European Standard specifies a method for the determination of the speed and effectiveness of the neutralizing potential of calcium carbonate and calcium magnesium carbonate liming materials by potentiometric titration with hydrochloric acid.
This method is applicable only to liming materials with a maximum particle size of 6,3 mm.
NOTE The type of liming material should be identified according to EN 14069 and the particle size should be determined according to EN 12948.
