Fertilizers - Determination of sulfates content using three different methods

This document specifies three different methods (Methods A, B and C) for the determination of sulfur present in fertilizers extracts in the form of sulfates. Method A specifies the gravimetric procedure. Method B specifies the method using inductively coupled plasma optical spectrometry (ICP-OES). Method C specifies the method using ion chromatography (IC).

Düngemittel - Bestimmung von Sulfat mit drei verschiedenen Verfahren

Das vorliegende Dokument legt drei verschiedene Verfahren (Verfahren A, B und C) für die Bestimmung des in Düngemittelextrakten vorliegenden Schwefels in Form von Sulfaten fest. Als Verfahren A ist das gravimetrische Verfahren festgelegt. Als Verfahren B ist die Bestimmung mittels optischer Emissionsspektro¬metrie mit induktiv gekoppeltem Plasma (ICP OES) festgelegt. Als Verfahren C ist die Vorgehensweise mittels Ionenchromatographie (IC) festgelegt.

Engrais - Dosage des sulfates selon trois méthodes différentes

Le présent document spécifie trois méthodes différentes (méthodes A, B et C) de dosage du soufre présent dans les extraits d’engrais sous forme de sulfate. La méthode A utilise la gravimétrie. La méthode B utilise la spectrométrie d’émission optique à plasma inductif (ICP-OES). La méthode C utilise la chromatographie par échange d’ions (IC).

This Technical Specification (CEN/TS) was approved by CEN on 11 May 2008 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, Cyprus, Czech Republic, Denmark, Estonia, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,
Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
