Fertilizers, liming materials and inhibitors - Sampling and sample preparation - Part 1: General sampling provisions

This document specifies sampling plans and methods of representative sampling of inorganic fertilizers, liming materials and inhibitors for physical and chemical analysis, from packages and containers up to and including 1 000 kg, in liquid and solid form. This document covers sampling of products in bulk only while in motion.
NOTE 1   The sampling of bulk heaps of specified types of fertilizers is covered in prEN 1482 3. Sampling for detection of microbial presence is covered by prEN 1482 4.
NOTE 2   The term product is used throughout the body of this document and is understood to include inorganic fertilizers, liming materials and inhibitors unless otherwise indicated.
It is applicable to the sampling of batches of fertilizer, liming material and inhibitors supplied or ready for supply to third parties, as such, or in smaller batches, each of which would be subject to local, national or regional legislation.
This document does not cover complete, statistical sampling plans.
This document is also applicable to the blends of products where inorganic fertilizers, liming materials, or inhibitors are the main part of the blend in quantity. If fertilizers, liming materials, or inhibitors are not the main part of the blend, the European Standard for the main part of the blend applies. In case a blend of fertilizing products is composed of parts in equal quantity, the user decides which standard to apply. Special care is needed to ensure that the blend is/stays homogeneous and well mixed when sampled.
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.

ANMERKUNG 2   Der Begriff Produkt wird durchgängig in diesem Dokument verwendet und schließt, wenn nicht anders angegeben, mineralische Düngemittel, Kalkdünger und Hemmstoffe ein.
Es ist anwendbar auf die Probenahme aus Losen von Düngemitteln, Kalkdünger und Hemmstoffen für den Weiterverkauf oder die Vorbereitung für den Weiterverkauf an Dritte als solche oder in kleineren Chargen, die der lokalen, nationalen oder regionalen Gesetzgebung unterliegen.
Dieses Dokument enthält keine vollständigen statistischen Probenahmepläne.
Dieses Dokument ist auch für Mischungen von Produkten anwendbar, in denen mineralische Düngemittel, Kalkdünger oder Hemmstoffe der quantitative Hauptbestandteil der Mischung sind. Wenn mineralische Düngemittel, Kalkdünger und Hemmstoffe nicht den Hauptbestandteil der Mischung ausmachen, ist die für den Hauptbestandteil geltende Europäische Norm anwendbar. Falls eine Düngemittelmischung aus Bestandteilen gleicher Menge besteht, entscheidet der Anwender, welche Norm angewendet wird. Es ist besonders darauf zu achten, dass die Mischung während der Probenahme homogen und gut vermischt ist und bleibt.
ANMERKUNG 3   Es liegt jedoch in der Verantwortung der Hersteller, Importeure und Verkäufer sicherzustellen, dass sie ein Produkt bereitstellen, das zum Zeitpunkt der Lieferung mit den Angaben auf dem Etikett übereinstimmt, und die Erwartungen des Endnutzers zum Zeitpunkt der Anwendung erfüllt.

Engrais, amendements minéraux basiques et inhibiteurs - Échantillonnage et préparation de l’échantillon - Partie 1 : Dispositions générales pour l’échantillonnage

Le présent document spécifie les plans d’échantillonnage et méthodes d’échantillonnage représentatif des engrais inorganiques, des amendements minéraux basiques et des inhibiteurs en vue d’une analyse physique et chimique, à partir d’emballages et de récipients d’une masse allant jusqu’à 1 000 kg inclus, sous forme liquide et sous forme solide. Le présent document traite de l’échantillonnage des produits en vrac uniquement lorsqu’ils sont en mouvement.
NOTE 1   L’échantillonnage de tas en vrac de types spécifiés d’engrais est traité dans le prEN 1482-3. L’échantillonnage pour la détection de la présence microbienne est traité dans le prEN 1482-4.
NOTE 2   Le terme « produit » est utilisé tout au long du présent document et s’entend comme incluant les engrais inorganiques, les amendements minéraux basiques et les inhibiteurs, sauf indication contraire.
Il s’applique aux lots d’engrais, d’amendements minéraux basiques et d’inhibiteurs livrés ou prêts à être livrés à une tierce partie, en l’état ou sous forme de lots plus petits, chacun étant soumis à la législation locale, nationale ou régionale en vigueur.
Le présent document ne couvre pas les plans d’échantillonnage statistiques complets.
Le présent document est également applicable aux mélanges de produits dans lesquels les engrais inorganiques, les amendements minéraux basiques ou les inhibiteurs représentent la majorité du mélange en quantité. Si les engrais inorganiques, les amendements minéraux basiques ou les inhibiteurs ne représentent pas la majorité du mélange, la Norme européenne du constituant principal du mélange s’applique.

European foreword
This document (prEN 1482-1:2023) has been prepared by Technical Committee CEN/TC 260 “Fertilizers
and liming materials”, the secretariat of which is held by DIN.
This document will supersede EN 1482-1:2007.
In comparison with the previous edition, the following technical modifications have been made:
— Title, Introduction, Scope, Normative References, Terms and definitions have been updated;
— Requirements on sampling for detonation testing, oil retention and other tests added to 4.3.2;
— The mass of the final sample in 4.3.4 has been specified;
— 5.11 has been updated.
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 microbiological presence in fertilizers.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association.
Introduction
This document (prEN 1482-1) covers the following aspects of sampling, derived from the International
Standards and documents indicated but presented in a simplified and condensed form. The titles of the
International Standards are given in the Bibliography.
— Sampling plans and quantitative data: ISO 8634, ISO/TR 5307, ISO/TR 7553 and Regulation (EU)
2019/1009;
— Sampling methods: ISO 3963;
— Reduction: ISO 7410, ISO 7742, ISO 8358;
— Sampling reports: ISO 5306.
prEN 1482-2 covers the general methods for the reduction and preparation of samples of inorganic
fertilizers, liming material and inhibitors for analysis. prEN 1482-3 covers the sampling of specified
fertilizers when stored in a static heap. prEN 1482-4 covers the sampling of specified fertilizers to be
tested for the presence of regulated microbes. It is under investigation whether this standard covers
organic and organo-mineral fertilizers.
Figure 1 gives a schematic diagram of the sampling and sample preparation process for solids.
The fundamental principle of representative sampling is that every particle has an equal chance of being
selected or rejected. In some circumstances this principle cannot easily be complied with, particularly in
the case of bulk heaps of solid fertilizers not specified in prEN 1482-3, or large storage tanks of liquid
fertilizers as the majority of the material cannot be reached by any sampling device. The fertilizer or
inhibitor in these cases should be sampled during transfer, during the building up of the heap, during the
filling of the storage tank, during dispatch or where it is being moved solely for sampling purposes.

1 Scope
This document specifies sampling plans and methods of representative sampling of inorganic fertilizers,
liming materials and inhibitors for physical and chemical analysis, from packages and containers up to
and including 1 000 kg, in liquid and solid form. This document covers sampling of products in bulk only
while in motion.
NOTE 1 The sampling of bulk heaps of specified types of fertilizers is covered in prEN 1482-3. Sampling for
detection of microbial presence is covered by prEN 1482-4.
NOTE 2 The term product is used throughout the body of this document and is understood to include inorganic
fertilizers, liming materials and inhibitors unless otherwise indicated.
It is applicable to the sampling of batches of fertilizer, liming material and inhibitors supplied or ready
for supply to third parties, as such, or in smaller batches, each of which would be subject to local, national
or regional legislation.
This document does not cover complete, statistical sampling plans.
This document is also applicable to the blends of products where inorganic fertilizers, liming materials,
or inhibitors are the main part of the blend in quantity. If fertilizers, liming materials, or inhibitors are
not the main part of the blend, the European Standard for the main part of the blend applies. In case a
blend of fertilizing products is composed of parts in equal quantity, the user decides which standard to
apply. Special care is needed to ensure that the blend is/stays homogeneous and well mixed when
sampled.
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.
