Carbonate liming materials - Determination of reactivity - Potentiometric titration method with hydrochloric acid; English version of DIN EN 13971:2008-05
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.
