Overview

ISO 14820-3:2020 - "Fertilizers and liming materials - Sampling and sample preparation - Part 3: Sampling of static heaps" provides standardized methods for obtaining representative samples from static heaps of mineral fertilizers and liming materials when sampling in motion is not possible. It is intended to support regulatory compliance and accurate statutory declarations by defining sampling plans, incremental sampling methods, and handling of aggregate/reduced/final samples for solid, single-nutrient, uniform complex, milled or granulated fertilizers (excluding blended fertilizers and tests affected by granulometric segregation).

Key topics and requirements

  • Scope and applicability: Sampling of bulk static heaps subject to legal requirements; not for blended fertilizers or particle-size analyses affected by segregation.
  • Lot characterization: Record physical properties before sampling - kind/type, texture, colour, storage conditions and presence of foreign matter.
  • Sampling plan elements: Must define lot boundary, volume/mass, number and location of sampling units, selected sampling units for increments, sketch-map (if needed), sampling points and minimum increment mass.
  • Sampling units: Total number of sampling units is based on lot size (e.g., minimum 10 units for lots ≤25 t; rules apply for larger lots up to >400 t).
  • Random selection: At least 10 sampling units must be selected randomly (random number tables/generator) for incremental sampling.
  • Incremental sample mass: Minimum increment from a sampling unit is 250 g; for liming materials coarser than 80 % passing 0.315 mm, each increment should be at least 500 g.
  • Volume/mass determination: Use production/purchase/sales records or estimate using methods in Annex A.
  • Sample processing: Incremental samples from units are combined to form aggregate, reduced and final samples in accordance with ISO 14820-1 procedures; final sample packaging and handling are specified to preserve representativity.

Practical applications

  • Ensures representative sampling for regulatory conformity checks, statutory nutrient declarations, and quality control where heaps are static.
  • Useful at farms, fertilizer production sites, warehouses, ports and distribution centers where bulk heaps are stored.
  • Supports laboratories and QA/QC teams to follow standardized procedures for sampling, chain-of-custody and final sample preparation prior to analysis.

Who should use this standard

  • National regulators and inspection authorities enforcing fertilizer/liming material legislation
  • Fertilizer manufacturers, packers and traders for compliance and dispute resolution
  • Accredited testing laboratories performing chemical or compositional analyses
  • Quality managers and auditors responsible for sampling protocols

Related standards

  • ISO 14820-1:2016 - Sampling and sample preparation - Part 1: Sampling (normative reference and procedures for aggregate/reduced/final samples).
  • ISO 14820 series - other parts cover sampling in different conditions and sample preparation.

Keywords: ISO 14820-3:2020, fertilizer sampling, static heaps, liming materials, sampling plan, incremental sampling, representative sample, regulatory compliance.

Introduction
The establishment of this document for methods of sampling and analysis is of utmost importance
to guarantee a uniform application and control of fair trade. Standardized methods of sampling and
analysis are essential elements in guaranteeing a high level of quality and safety of fertilizers for the
benefit of purchasers. Competent authorities have limited resources for conformity assessment, and
these resources are most efficiently deployed at the downstream end of the supply chain. Representative
sampling is essential to achieve reliable analytical results.
The fundamental principle of representative sampling is that every particle has an equal chance of
being sampled. This principle cannot easily be complied with in the case of bulk static heaps of solid
fertilizers as a large proportion of the material cannot practically be reached by any sampling device.
Wherever possible, this fertilizer should be sampled during transfer, during the building up of the heap,
during dispatch or where it can practically be moved solely for sampling purposes. However, in some
cases, sampling in the way described is not practicable. Sampling of static heaps should only be carried
out when the product is not in motion.

Introduction
L'établissement de ce document pour les méthodes d'échantillonnage et d'analyse est de la plus
haute importance afin de garantir une application et un contrôle uniformes du commerce équitable.
Les méthodes normalisées d’échantillonnage et d’analyse sont des éléments essentiels pour assurer
un haut niveau de qualité et de sécurité des engrais dans l’intérêt des acheteurs. Les autorités
compétentes disposent de ressources limitées pour l'évaluation de la conformité, et ces ressources sont
déployées le plus efficacement en aval de la chaîne d'approvisionnement. Il est impératif de réaliser un
échantillonnage représentatif afin d’obtenir des résultats d’analyse fiables.
Le principe fondamental de l’échantillonnage représentatif est que chaque particule a une chance égale
d’être échantillonnée. Il n’est pas facile de respecter ce principe dans le cas des tas statiques d’engrais
solides en vrac car une grande partie du produit ne peut être atteinte facilement par un dispositif
d’échantillonnage. Dans la mesure du possible, il convient d’échantillonner cet engrais pendant le
transfert, pendant la formation du tas, pendant l’expédition ou encore dans le flux du produit en le
déplaçant aux seules fins de l’échantillonnage. Cependant, dans certains cas, il est impossible de réaliser
l’échantillonnage de cette manière. L'échantillonnage des tas statiques devrait uniquement être réalisé
lorsque le produit n'est pas en mouvement.

The article discusses ISO 14820-3:2020, which is a document that provides guidelines for sampling mineral fertilizers and liming materials. It applies to situations where these materials are being supplied or prepared for supply to third parties, and where legal requirements must be met. The document specifies plans and methods for sampling solid fertilizers or liming materials from static heaps, when sampling in motion is not possible. The purpose of sampling is to ensure compliance with legal requirements, particularly regarding the accuracy of statutory declarations. The methods outlined in the document are not suitable for obtaining samples for physical size or chemical analysis that could be affected by particle segregation. The guidelines apply to single nutrient fertilizers, uniform complex fertilizers, and milled or granulated fertilizers and liming materials. However, they are not suitable for sampling other types of fertilizers, such as blended fertilizers. The term "fertilizer" in the document includes liming materials, unless otherwise specified.

ISO 14820-3:2020 is a document that provides guidelines for sampling mineral fertilizers and liming materials. It applies to fertilizers and liming materials that are being supplied or are ready for supply to third parties, and are subject to legal requirements. The document specifies plans and methods for sampling solid fertilizers or liming materials from static heaps when sampling in motion is not possible. The purpose of sampling is to ensure compliance with legal requirements, particularly in relation to the accuracy of statutory declarations. The methods described in the document are not suitable for obtaining samples for physical size analysis or chemical analysis that could be affected by particle granulometric segregation. The document is applicable to single nutrient fertilizers, uniform complex fertilizers, and milled or granulated fertilizers and liming materials. It does not cover other types of fertilizers such as blended fertilizers. The term "fertilizer" in this document also includes liming materials.
