DIN EN 12945:2009 PDF

Scope: This European Standard specifies two methods for the determination of the neutralizing value (NV) of liming materials. Method A is applicable to all liming materials except silicate liming materials and liming materials with more than 3 % P₂O₅. Method B is applicable to all liming materials except products with more than 3 % mass fraction P205, and calcined and slaked products of carbonate origin, NOTE The methods described in ISO 6598 and ISO 7497 can be used for the determination of P205 content (see [2] and [3]).
