It is applicable to fertilizing products, which are classified as PFC 2 or the PFC 2 component in PFC 7 of Regulation (EU) 2019/1009 [2].

This document specifies references to the methods for the determination of the following physical and chemical properties and specific contaminants in liming materials:

Determination of the cadmium content;

Determination of the chromium VI content;

Determination of the mercury content;

Determination of the nickel content;

Determination of the lead content;

Determination of the arsenic content;

Determination of the total chromium content;

Determination of neutralizing value;

Determination of the reactivity;

Determination of the grain size/granulometry;
