- 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. Therefore, the particle size shall be determined according to EN 12948. NOTE In addition, the type of liming material should be identified according to prEN 14069. Regarding the precision of the method, the results are not used to declare a value but to classify the different products groups.
