Liming materials - Determination of neutralizing value - Titrimetric methods
|Publication Date:||1 April 2014|

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.
Method B is applicable to all liming materials.
Both methods do not correctly take into account the potential neutralizing value of material containing more than 3 % P2O5. For a more accurate agronomic assessment of products containing more than 3 % P2O5 determine the liming efficiency according to EN 14984.
NOTE The methods described in ISO 6598  and ISO 7497  can be used for the determination of P2O5 content. Further information on P analyses is given in  and .
