Liming materials - Determination of neutralizing value - Titrimetric methods

Liming materials - Determination of neutralizing value - Titrimetric methods

This European Standard specifies two methods for the determination of the neutralizing value (NV) of liming materials.
Method A is applicable for liming materials except silicate liming materials and liming materials with more than 3 % P2O5.
Method B is applicable for all liming materials except those with more than 3 % P2O5.
NOTE   The methods described in ISO 6598 and ISO 7497 can be used for the determination of P2O5 content.

Calcium-/Magnesium-Bodenverbesserungsmittel - Bestimmung des Neutralisationswertes - Titrimetrische Verfahren

Verfahren B gilt für alle Calcium-/Magnesium-Bodenverbesserungsmittel mit Ausnahme solcher mit über 3 % P2O5 (Massenanteil).
ANMERKUNG   Zur Bestimmung des P2O5 -Gehalts können die in ISO 6598 und ISO 7497 beschriebenen Verfahren verwendet werden.

Amendements minéraux basiques - Détermination de la valeur neutralisation - Méthodes par titrimétrie

La présente Norme européenne spécifie deux méthodes pour la détermination de la valeur neutralisante (VN) des amendements minéraux basiques.
La méthode A est applicable aux amendements minéraux basiques, à l'exception des amendements minéraux basiques sidérurgiques et des amendements basiques contenant plus de 3 % de P2O5.
La méthode B est applicable à tous les amendements minéraux basiques à l'exception de ceux contenant plus de 3 % de P2O5.
NOTE   Les méthodes ISO 6598 et ISO 7497 peuvent être utilisées pour la détermination de la teneur en P2O5.

Fertilizers, liming materials and inhibitors - Sampling and sample preparation - Part 3: Sampling of static heaps
EN 1482-3:2024

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.

Fertilizers, liming materials and inhibitors - Sampling and sample preparation - Part 1: General sampling provisions
EN 1482-1:2024

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.
