Plant biostimulants - Sampling and sample preparation - Part 1: Sampling

This European Standard specifies sampling plans and methods of representative sampling of plant biostimulants to obtain samples for physical, chemical and biological analysis.
It is applicable to the sampling of lots of plant biostimulants supplied or ready for supply to third parties, as such, or in smaller lots.
It is also applicable to the sampling of blends of fertilizing products where plant biostimulants are main part of the blend. Otherwise, deliverables of sampling relevant for the main part of the blend apply.
The European Standard is intended to be used by manufacturers, buyers and competent authorities to obtain samples prior to transport and supply it to a laboratory for testing.
NOTE   This European standard is applicable to the category of EU fertilizing product (plant biostimulants) in the meaning of the Regulation (EU) 2019/1009.

Pflanzen-Biostimulanzien - Probenahme und Probenvorbereitung - Teil 1: Probenahme

Dieses Dokument legt Probenahmepläne und Verfahren der repräsentativen Probenahme aus Pflanzen-Biostimulanzien zur Gewinnung von Proben für physikalische, chemische und biologische Analysen fest.
Es ist auf die Probenahme aus Partien von Pflanzen-Biostimulanzien, die als solche oder in kleineren Partien an Dritte geliefert wurden oder lieferbereit sind, anwendbar.
Es ist zudem auf die Probenahme aus Mischungen von Düngeprodukten anwendbar, bei denen Pflanzen-Biostimulanzien den Hauptbestandteil der Mischung darstellen. Andernfalls gelten die für den Haupt-bestandteil der Mischung relevanten Vorgaben für die Probenahme.
Dieses Dokument ist für die Verwendung durch Hersteller, Käufer und die zuständigen Behörden bestimmt, um Proben vor dem Transport zu erhalten und diese zur Untersuchung an ein Labor zu übergeben.
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 1 : Échantillonnage

Le présent document spécifie les plans d’échantillonnage et les méthodes d’échantillonnage représentatif de biostimulants des végétaux pour obtenir des échantillons en vue d’une analyse physique, chimique et biologique.
Il est applicable à l’échantillonnage de lots de biostimulants des végétaux livrés ou prêts à être livrés à une tierce partie, en l’état ou sous forme de lots plus petits.
Il est également applicable à l’échantillonnage de mélanges de fertilisants dans lesquels les biostimulants des végétaux représentent la majorité du mélange. Dans le cas contraire, ce sont les livrables de l’échantillonnage pertinents pour le fertilisant majoritairement présent dans le mélange qui s’appliquent.
Le présent document est destiné à être utilisé par les fabricants, acheteurs et autorités compétentes pour obtenir des échantillons avant de les transporter et de les fournir à un laboratoire pour essai.
NOTE   Le présent document est applicable à la catégorie de fertilisants UE (biostimulants des végétaux) au sens du Règlement (UE) 2019/1009.
