Inorganic fertilizers - Determination of specific inhibitors

This document specifies references to the methods for the determination of nitrification inhibitors and urease inhibitors in inorganic fertilizers.
This document is applicable to EU fertilizing products classified as PFC 1(C) and PFC 7 as long as the blend only consists of EU fertilizing products classified as PFC 1(C), PFC 2 and PFC 5 as specified in the Regulation (EU) 2019/1009 [1].

Anorganische Düngemittel - Bestimmung spezifischer Hemmstoffe

Dieses Dokument legt Verweisungen auf Verfahren zur Bestimmung von in anorganischen Düngemitteln enthaltenen Nitrifikationshemmstoffen und Ureasehemmstoffen fest.
Dieses Dokument ist anwendbar auf EU Düngeprodukte der Kategorien PFC 1(C) und PFC 7, vorausgesetzt, die Mischung besteht ausschließlich aus EU Düngeprodukten der Kategorie PFC 1(C), PFC 2 und PFC 5 der Verordnung (EU) 2019/1009 [1].

Engrais inorganiques - Détermination des inhibiteurs spécifiques

Le présent document spécifie les références des méthodes de détermination des inhibiteurs de nitrification et des inhibiteurs d'uréase dans les engrais inorganiques.
Le présent document est applicable aux fertilisants UE classés en PFC 1(C) et PFC 7 tant que la combinaison ne se compose que de fertilisants UE classés en PFC 1(C), PFC 2 et PFC 5, comme spécifié dans le règlement (UE) 2019/1009 [1].

Anorganska gnojila - Določevanje specifičnih inhibitorjev

Ta dokument navaja metode za določevanje vsebnosti inhibitorja nitrifikacije, vsebnosti inhibitorja denitrifikacije in vsebnosti inhibitorja ureaze v anorganskih gnojilih.

This Technical Specification (CEN/TS) was approved by CEN on 13 March 2022 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and
United Kingdom.
