This Technical Specification (CEN/TS) was approved by CEN on 3 January 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

Different product functions warrant different product safety, quality and quantity requirements adapted

to their different intended uses. EU fertilizing products have therefore been divided into different product

function categories (PFCs), which should each be subject to specific safety and quality requirements, as

specified in the Regulation (EC) No 2019/1009 [2].

Growing media have been classified as PFC 4, as specified in the Regulation (EC) No 2019/1009 [2]. The

specific safety, quality and quantity requirements in relation to some of the specific parameters (i.e. the
