CEN - EN 12945

Liming materials - Determination of neutralizing value - Titrimetric methods

active, Most Current
Organization: CEN
Publication Date: 1 April 2014
Status: active
Page Count: 18
ICS Code (Fertilizers): 65.080
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.

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].
