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 [1] and ISO 7497 [2] can be used for the determination of P2O5
content. Further information on P analyses is given in [3] and [4].
