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.

Overview
FprEN 1482-3 is a CEN draft European standard for the sampling of static heaps of fertilizers, liming materials, and inhibitors. It forms part of the EN 1482 series on sampling and sample preparation and is designed to support consistent, representative sampling of bulk material stored in a single mass.
This standard is especially relevant where products are stored in static heaps and cannot practically be moved for sampling under general methods. Its main purpose is to help users obtain samples that better reflect the batch composition, supporting quality control, compliance assessment, and reliable product declaration checks.
The scope applies to solid fertilizers and liming materials with uniform composition and no tendency to segregate. It also notes that the method may be used for other products or blends if both parties agree, although segregation risk can make representative sampling more difficult.
Key Topics
FprEN 1482-3 provides practical guidance for sampling plans, sampling units, and incremental sampling from static heaps. It emphasizes planning and documentation to ensure reproducible results.
Key topics include:
- Batch characterization before sampling
- Definition of a sampling plan
- Determination of batch volume or mass
- Selection of sampling units and sampling points
- Minimum mass for incremental samples
- Procedures for combining and reducing samples
- Preparation of final laboratory samples
- Completion of a sampling report
The standard also addresses the need to avoid biased sampling, stating that sampling only from the base or one part of a heap does not produce a representative sample. Sampling apparatus must be clean, dry, inert, and suitable for the product being sampled.
The document includes practical provisions for products with different characteristics, such as the use of a sampling spear and, for wet liming materials, a tube shovel. Informative annexes provide examples for estimating heap volume and an alternative screening method.
Applications
FprEN 1482-3 is useful in supply chains where fertilizer sampling and liming material sampling are needed for:
- Manufacturers verifying batch quality before dispatch
- Importers checking consistency of delivered goods
- Sellers and distributors supporting transaction agreements
- Laboratories preparing representative test samples
- Regulatory and compliance workflows linked to EU fertilising products
The standard is particularly valuable for bulk storage operations, where static heap sampling helps maintain traceability and supports claims related to product label declarations and end-user expectations.
Related Standards
FprEN 1482-3 is part of the broader EN 1482 framework and should be read alongside related documents, including:
- EN 1482-1 - General sampling provisions
- EN 1482-2 - General sample preparation provisions
- EN 1482-4 - Sampling for microbial presence
- prEN 12944-1 - Vocabulary for fertilizers, liming materials and inhibitors
It also references technical and regulatory context relevant to European standardization, including compliance-related sampling practices for fertilizing products.

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.
