Organic and organo-mineral fertilizers - Determination of the mercury content

This document specifies a method for determination of the content of mercury (Hg) in organic fertilizers and organo-mineral fertilizers using (cold) vapour generation apparatus coupled to an atomic absorption spectrophotometer and a method using a direct amalgamation technique. It is applicable to aqua regia digests prepared according to CEN/TS 17768.
NOTE   It is also possible to use other suitable methods for the determination of mercury described in Annex A if users prove that the method gives the same results as the methods described in this standard.

Organische und organisch-mineralische Düngemittel - Bestimmung des Quecksilbergehaltes

Dieses Dokument legt ein Verfahren zur Bestimmung des Quecksilbergehalts (Hg) in organischen Dünge¬mitteln und organisch-mineralischen Düngemitteln mittels eines Systems der (Kalt )Dampftechnik, gekoppelt mit einem Atomabsorptionsspektrometer und einem Verfahren, das auf einer direkten Amalgamierungs¬technik beruht, fest. Es ist anzuwenden für Königswasseraufschlüsse, die nach CEN/TS 17768 hergestellt werden.
ANMERKUNG   Auch die Anwendung anderer, in Anhang A beschriebener geeigneter Verfahren der Quecksilber-bestimmung ist möglich, sofern die Anwender nachweisen, dass das Verfahren zu gleichen Ergebnissen führt wie die in dieser Norm beschriebenen Verfahren.

Engrais organiques et organo-minéraux - Détermination de la teneur en mercure

Le présent document spécifie une méthode pour la détermination de la teneur en mercure (Hg) dans les engrais organiques et organo-minéraux avec un appareil de génération de vapeur (à froid) couplé à un spectrophotomètre d’absorption atomique et une méthode utilisant une technique d’amalgamation directe. Il est applicable aux digestats à l’eau régale préparés conformément à la CEN/TS 17768.
NOTE   Il est aussi possible d’utiliser d’autres méthodes adaptées pour le dosage du mercure décrites dans l’Annexe A, si l’utilisateur prouve que la méthode conduit aux mêmes résultats que les méthodes décrites dans la présente norme.

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,
