|ICS Code (Fertilizers):||65.080|
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 P2O5, 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 P2O5 content (see  and ).
