(Main)Inorganic fertilizers - Determination of chelating and complexing agents
Inorganic fertilizers - Determination of chelating and complexing agents
This document specifies references to the methods for the determination of specific micronutrients, chelating and complexing agents. The document specifies references to the methods and requirements for inorganic micronutrient fertilizers in accordance with PFC 1 (C) (II) as specified in the Regulation (EU) 2019/1009 [1].
Inorganic micronutrient materials for this purpose are micronutrient salts or oxide and hydroxides, or micronutrient chelates or complexes and mixtures of them, in powder or granular form, aqueous or suspension preparation.
Anorganische Düngemittel - Bestimmung von Chelat- und Komplexbildnern
Dieses Dokument legt Verweisungen auf Verfahren zur Bestimmung von spezifischen Spurennährstoffen, Chelatbildnern und Komplexbildnern fest. Das Dokument legt Verweisungen auf Verfahren und Anforderungen für anorganische Spurennährstoff-Düngemittel in Übereinstimmung mit PFC 1(C)(II) der Verordnung (EU) 2019/1009 [1] fest.
Anorganische Spurennährstoffmaterialien für diesen Zweck sind Spurennährstoffsalze oder oxide und hydroxide oder Spurennährstoffchelate oder komplexe und Mischungen davon, in Pulver- oder Granulatform, wässrigen Präparaten oder Suspensionen.
Engrais inorganiques - Détermination des agents chélatants et complexants
Le présent document spécifie les références aux méthodes de détermination des oligo-éléments spécifiques, des agents chélatants et complexants. Le document spécifie les références aux méthodes et aux exigences relatives aux engrais inorganiques à oligo-éléments conformément à la PFC 1 (C) (II), tel que spécifié dans le règlement (UE) 2019/1009 [1].
Les matières inorganiques à oligo-éléments utilisées à cette fin sont des oligo-éléments sous forme de sels ou d'oxyde ou d'hydroxydes, ou des chélates ou des complexes d'oligo-éléments et des mélanges de ceux-ci, sous forme de poudre ou de granulés, en préparation aqueuse ou en suspension.
Anorganska gnojila - Določevanje sredstev za kelatiranje in kompleksiranje
Ta dokument navaja metode za določevanje specifičnih mikrohranil, sredstev za kelatiranje in kompleksiranje. Dokument določa metode in zahteve za anorganska-mineralna gnojila v skladu s funkcijsko kategorijo PFC 1(C) (II), kot je določeno v Uredbi (EU) 2019/1009 [1].
Anorgansko-mineralna sredstva za ta namen so mikrohranilne soli ali oksidi in hidroksidi ali mikrohranila, ki vsebujejo kelate ali komplekse mikrohranil in/ali njihove mešanice v prahu ali granulah, vodne ali suspenzijske pripravke.

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.
