Organic and organo-mineral fertilizers - Digestion by aqua regia for subsequent determination of elements
This document specifies the procedure for the digestion of different organic fertilizers and organo-mineral fertilizers with aqua regia to enable a subsequent determination of elements.
The extracts are suitable for analysis using CEN/TS 17770 and CEN/TS 17769.
NOTE Alternatively, inductively coupled plasma mass spectrometry (ICP-MS) can be used for the measurement if the user proves that the method gives the same results.
Organische und organisch-mineralische Düngemittel - Aufschluss durch Königswasser zur anschließenden Bestimmung der Elemente
Dieses Dokument legt das Verfahren für den Aufschluss verschiedener organischer Düngemittel und organisch-mineralischer Düngemittel mit Königswasser fest, um eine anschließende Bestimmung der Elemente zu ermöglichen.
Die Extrakte sind für die Analyse nach CEN/TS 17770 und CEN/TS 17769 geeignet.
ANMERKUNG Alternativ kann die Massenspektrometrie mit induktiv gekoppeltem Plasma (ICP MS) für die Messung angewendet werden, sofern der Anwender nachweist, dass das Verfahren zu den gleichen Ergebnissen führt.
Engrais organiques et organo-minéraux - Digestion à l'eau régale pour le dosage ultérieur des éléments
Le présent document spécifie le mode opératoire de digestion de différents engrais organiques et organo-minéraux à l’eau régale pour permettre le dosage ultérieur des éléments.
Les extraits sont adaptés pour une analyse conformément à la CEN/TS 17770 et la CEN/TS 17769.
NOTE Il est également possible d’utiliser la spectrométrie de masse couplée à un plasma inductif (ICP-MS) pour la mesure si l’utilisateur prouve que la méthode conduit aux mêmes résultats.

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.
