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.

Introduction
Regulation (EU) 2019/1009 [1] 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), which has been divided into two groups PFC 1(C)
(I) [inorganic macronutrients fertilizers] and PFC 1(C)(II) [inorganic micronutrient fertilizers].
Micronutrients are considered to be, in plant nutrition, a number of elements known to be needed in small
amounts for proper plant growth and development. The most common are Iron (Fe), Manganese (Mn),
Molybdenum (Mo), Copper (Cu), Zinc (Zn) and Boron (B).
If an inorganic micronutrient fertilizer contains a substance, or one of the substances in the mixture, which
is intended to enhance the long term availability to plants of micronutrients in the EU fertilizing product,
that substance is either a chelating agent or a complexing agent.
The specific safety and quality requirements in relation to the determination of chelating and complexing
agents in inorganic micronutrient fertilizers (PFC 1(C)(II)) are defined in this document as well as the
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 [1].
1 Scope

chelating and complexing agents. The document specifies references to the methods and requirements for
