European foreword
This document (prEN 1482-3:2026) 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 the CEN Enquiry.
This document will supersede EN 1482-3:2024.
— extension of the scope to include sampling of uniform organic fertilizers and uniform organo-
mineral fertilizers.
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.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
Introduction
Standardized methods of sampling and analysis are essential in uniformly establishing the compliance
of fertilizing products with legal requirements, as well as any information and/or declarations given on
their supply or readiness for supply.
The aim of these standardized methods is to obtain a representative sample of the whole batch supplied
or ready for supply. General methods to obtain such a sample are given in EN 1482-1.
However, where the product is stored in large static heaps it is not always possible or practical to put
the product into motion for a sampling method according to EN 1482-1 to be used. Research has found
that for a limited number of types of products a representative sample can be obtained by sampling
directly from the static heap.
This document describes the method to be used for sampling static heaps of the specified products
within its scope.
1 Scope
This document is applicable to the sampling of solid fertilizers and liming materials that have a uniform
composition and have no tendency to segregate.
NOTE 1 The term product is used throughout the body of this document and is understood to include
fertilizers, liming materials and inhibitors unless otherwise indicated.
NOTE 2 Manufacturers, importers and sellers can choose to use this method to obtain samples of other
products or blends as well as long as both parties to a transaction agree. The build-up of a static heap often leads
to granulometric segregation, which makes the collection of a truly representative sample of many products and
blends unlikely.
NOTE 3 It is the responsibility of manufacturers, importers and sellers, however, to ensure they supply a
product that complies with its label declaration at the moment of delivery and fulfils the expectations of the end
user at the moment of application.
NOTE 4 A method of obtaining a screening sample from a static heap can be found in Annex B.
