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 % P 2O 5. For a more accurate agronomic assessment of products containing more than 3 % P 2O 5 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 P 2O 5 content. Further information on P analyses is given in [3] and [4].
