Plant biostimulants - Sampling and sample preparation - Part 2: Sample preparation

This document specifies methods for the reduction and preparation of samples of non-microbial plant biostimulants including those intended for determination of microbial pathogens and sets out the requirements for sample preparation reports. It specifies methods for the preparation of test samples and test portions from laboratory samples of plant biostimulants for subsequent chemical, biological or physical analysis.
It is also applicable to the sample preparation of blends of fertilizing products where plant biostimulants are main part of the blend. Otherwise, deliverables of sample preparation relevant for the main part of the blend apply.
This document does not include methods for the reduction and preparation of samples of microbial plant biostimulants, which will be covered by a different European Standard.
NOTE   This document is applicable to the category of EU fertilizing product (plant biostimulants) in the meaning of Regulation (EU) 2019/1009.

Pflanzen-Biostimulanzien - Probenahme und Probenvorbereitung - Teil 2: Probenvorbereitung

Dieses Dokument legt Verfahren zur Reduzierung und Vorbereitung von Proben von nicht-mikrobiellen Pflanzen-Biostimulanzien, einschließlich solcher, die für die Bestimmung von mikrobiellen Pathogenen vorgesehen sind, fest und regelt die Anforderungen an Berichte zur Probenvorbereitung. Es legt Verfahren zur Herstellung von Untersuchungsproben und Prüfmengen aus Laborproben von Pflanzen-Biostimulanzien für nachfolgende chemische, biologische oder physikalische Analysen fest.
Es ist zudem auf die Probenvorbereitung aus Mischungen von Düngemittelprodukten, bei denen Pflanzen-Biostimulanzien den Hauptbestandteil der Mischung darstellen, anwendbar. Andernfalls gelten die für den Hauptbestandteil der Mischung relevanten Vorgaben für die Probenvorbereitung.
Dieses Dokument umfasst keine Verfahren zur Reduzierung und Vorbereitung von Proben von mikrobiellen Pflanzen-Biostimulanzien; dies wird von einer anderen Europäischen Norm abgedeckt.
ANMERKUNG   Dieses Dokument ist anwendbar auf die Kategorie von EU Düngeprodukten (Pflanzen-Biostimulanzien) im Sinne der Verordnung (EU) 2019/1009.

Biostimulants des végétaux - Échantillonnage et préparation des échantillons - Partie 2 : Préparation des échantillons

Le présent document spécifie des méthodes de réduction et de préparation des échantillons de biostimulants non microbiens des végétaux, y compris celles conçues pour la détermination des pathogènes microbiens, et précise les exigences relatives aux rapports de préparation des échantillons. Il spécifie des méthodes de préparation des échantillons pour essai et de prises d’essai à partir d’échantillons pour laboratoire de biostimulants des végétaux en vue d’une analyse chimique, biologique ou physique ultérieure.
Il est également applicable à la préparation des échantillons de mélanges de fertilisants dans lesquels les biostimulants des végétaux représentent la majorité du mélange. Dans le cas contraire, ce sont les livrables de la préparation d’échantillons pertinents pour le fertilisant majoritairement présent dans le mélange qui s’appliquent.
Le présent document n’inclut pas de méthodes de réduction et de préparation des échantillons de biostimulants microbiens des végétaux. Ces derniers seront couverts par une autre Norme européenne.
NOTE   Le présent document est applicable à la catégorie de fertilisants UE (biostimulants des végétaux) au sens du Règlement (UE) 2019/1009.
