Liming materials - Determination of neutralizing value - Titrimetric methods; German version EN 12945:2014/prA1:2014
Most recent standard

Summary

This document 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. Fore a more accurate agronomic assessment of products containing more than 3 % P2O5 the liming efficiency is determined according to EN 14984. The Amendment 1 takes into account the possibility to express results of neutralizing value measurement as HO- equivalent. The new added Annex B covers the appropriate conversion tables (CaO to HO- respectively HO- to CaO).
