Fertilizing products - Determination of the stability of fertilizing products containing micronutrient chelates at different pHs

This document specifies a method for the determination of the soluble metal that remains in solution at different pHs after the application of a solution of the fertilizer substance containing micronutrient chelates in a tap water solution used as a reference.
The method applies to fertilizing products containing chelated micronutrients.

Düngeprodukte - Bestimmung der Stabilität von Spurennährstoffchelaten in Düngeprodukten bei verschiedenen pH Werten

Dieses Dokument legt ein Verfahren zur Bestimmung des löslichen Metalls fest, das nach der Anwendung einer Düngemittellösung, die Spurennährstoffchelate enthält, bei verschiedenen pH Werten in einer als Referenz verwendeten Leitungswasserlösung in Lösung bleibt.
Das Verfahren ist bei Düngeprodukten anwendbar, die chelatisierte Spurennährstoffe enthalten.

Fertilisants - Détermination de la stabilité des fertilisants contenant des oligo-éléments chélatés à différents pH

Le présent document spécifie une méthode pour la détermination, à différents pH, des métaux solubles qui restent en solution après l’ajout d’une solution de substance fertilisante contenant des oligo-éléments chélatés dans une eau du robinet de référence.
La méthode s’applique aux fertilisants contenant des oligo-éléments chélatés.

Sredstva za gnojenje - Določanje stabilnosti sredstev za gnojenje, ki vsebujejo kelate mikrohranil pri različnih pH-vrednostih

Ta dokument določa metodo za določanje topne kovine, ki ostane v raztopini pri različnih pH-vrednostih po nanosu raztopine gnojilne snovi, ki vsebuje kelate mikrohranil, v raztopini vode iz pipe, ki se uporablja kot referenca.
Metoda se uporablja za sredstva za gnojenje, ki vsebujejo kelatirana mikrohranila.

This Technical Specification (CEN/TS) was approved by CEN on 21 February 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,
