This document is applicable to the sampling of the following solid inorganic fertilizers and liming materials supplied or ready for supply, and stored in static heaps:
- Single nutrient fertilizers,
- Uniform complex fertilizers,
- Milled, granulated or dredged liming materials,
- Any other materials deemed suitable for sampling by the method described in this part of the standard,
for the purpose of testing for compliance with legal requirements and other descriptions and declarations.
NOTE 1 The term “fertilizer” is used throughout the body of this document and includes liming materials and inhibitors unless otherwise indicated.
NOTE 2 Manufacturers, importers and sellers might 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 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.

It also specifies methods for the preparation of test samples and test portions from laboratory samples of fertilizer for subsequent chemical or physical analysis. It does not cover the preparation of samples for certain physical tests which require test portions of more than 2 kg.
NOTE 1 The term “fertilizer” is used throughout the body of this document and is understood to include liming materials and inhibitors unless otherwise indicated.
NOTE 2 In relation to the procedures set out in this part of the standard any special procedures specific to a particular test method will be set out in that method standard.

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.

This document specifies a method for verifying that hexavalent chromium (Cr(VI)) is not present in plant biostimulants.
This document is applicable to all types of plant biostimulants (solid and liquid) used in agriculture.
The method specified is suitable to quantify the chromium(VI) content in plant biostimulants down to 2 mg/kg.
The results obtained from this method are strictly dependent on the extraction conditions. Results obtained by using other extraction procedures (extraction solution, pH, extraction time, etc.) are not comparable with the results produced by the procedure specified in this document.
This document is applicable to the blends of fertilizing products where a blend is a mix of at least two of the following component EU fertilising products: Fertilizers, Liming Materials, Soil Improvers, Growing Media, Inhibitors, Plant Biostimulants and where the following category Plant Biostimulants is the highest percentage in the blend by mass or volume, or in the case of liquid form by dry mass. If Plant Biostimulants is not the highest percentage in the blend, the European Standard for the highest percentage of the blend applies. In case a blend of fertilizing products is composed of components in equal quantity or in case the component EU fertilising products used for the blend have identical formulations , the user decides which standard to apply.
