This Technical Specification (CEN/TS) was approved by CEN on 13 March 2022 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,

Introduction
Regulation (EU) 2019/1009 [2] lays down the rules on the making available on the market of EU
fertilizing products and the specific safety and quality requirements for the defined product function
categories (PFCs). Inorganic fertilizers have been classified into PFC 1(C).
The specific safety and quality requirements in relation to the following specific micronutrients are
defined in this document as well as normative references of the test methods to be used in order to
measure the compliance with the related requirement in the Regulation (EU) 2019/1009 [2].

1 Scope
This document specifies references to methods for the determination of the content of the following
specific micronutrients in inorganic fertilizers:
— the total boron content;
— the total cobalt content;
— the total copper and zinc content;
— the total iron content;
— the total manganese content;
— total molybdenum content;
— the water-soluble boron content;
— the water-soluble cobalt content;
— the water-soluble copper content;
