标准范围

This document specifies a method for determining the reactivity of calcium carbonate and calcium magnesium carbonate liming materials. It assesses the speed and effectiveness of their neutralising potential by automatic titration with citric acid.
This method is applicable only to liming materials with a maximum particle size of 6,3 mm determined in accordance with ISO 20977.
NOTE For marble dolomite (BET procedure as defined in ISO 9277 below 500 m ²/kg), see EN 14984.
