European foreword
This document (prEN 1482-4:2022) has been prepared by Technical Committee CEN/TC 260 “Fertilizers
and liming materials”, the secretariat of which is held by DIN.
This document is currently submitted to CEN Enquiry.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association.
EN 1482, Fertilizers, liming materials and inhibitors — Sampling and Sample preparation consists of four
parts:
— Part 1: General sampling provisions;
— Part 2: General sample preparation provisions;
— Part 3: Sampling of static heaps;
— Part 4: Sampling for microbial presence.
A fifth part on sampling for organic and organo-mineral fertilizers is under preparation.

Introduction
In order to check compliance with the related requirements of Regulation (EU) 2019/1009 [1] methods
have to be defined in standards. In this document the method for obtaining a sample from organic
fertilizers, organo-mineral fertilizers and inorganic fertilizers containing more than 1 % by mass of
organic carbon to test for levels of controlled microbial presence is defined. Any final sample collected by
following the procedures described in this standard is considered to be representative for the sampled
portion.

1 Scope
This document specifies the method for taking a sample from both solid and liquid forms of organic
fertilizers, organo-mineral fertilizers and inorganic fertilizers containing more than 1 % by mass of
organic carbon, when in packages, containers or in bulk, to test for levels of controlled microbial presence.
This document is not applicable to sampling for microbial presence in growing media and soil improvers
(see EN 12579 [4]) or plant biostimulants (see CEN/TS 17702-1 [2]).

a laboratory sample
3.5
sampling point
point from which the incremental sample is taken
3.6
incremental sample
quantity of material taken from one sampling point

4 Sampling
4.1 General requirements
4.1.1 All sampling equipment shall be clean, dry and made from materials which will not contaminate
the sample. Sampling equipment shall be appropriate to the physical characteristics of the product in
order to ensure a representative sample of the product is obtained, i.e. size of individual units of the
product, width and depth of flow of material being sampled in motion. Examples for sampling equipment
for various sampling methods are prescribed in EN 1482-1.
4.1.2 Sampling equipment, including sample containers, shall be either unused or have been subject to
a sterilization process before use. To avoid cross-contamination, a set of unused or sterilized equipment
shall be used to obtain each individual segment sample. When using new, unopened plastic bags, the bags
do not need sterilization.
4.1.3 Steps shall be taken when sampling, sample handling and sample transport to avoid any sort of
contamination of the sample. Sampling shall be undertaken by a competent person acceptable to the
parties involved.
