Fertilizers - Determination of magnesium by atomic absorption spectrometry

This Technical Specification specifies a method for the determination of the magnesium content in fertilizer extracts using atomic absorption spectrometry (AAS).
This method is applicable to EC fertilizer extracts obtained according to CEN/TS 15960 and CEN/TS 15961, for which a declaration of the total magnesium and/or water soluble magnesium content is required, with the exceptions of the following fertilizers according to [4], Annex I D relating to secondary nutrients:
-   type 4 (kieserite);
-   type 5 (magnesium sulfate) and type 5.1 (magnesium sulfate solution);
-   type 7 (kieserite with potassium sulfate)
to which [4], method 8.8, applies.
NOTE   Method 8.8 is covered by CEN/TS 16198 (see Bibliography).
The method applies to all fertilizer extracts containing elements in quantities that might interfere with the complexometric determination of magnesium.

Düngemittel - Bestimmung von Magnesium mit Atomabsorptionsspektrometrie

Diese Technische Spezifikation legt ein Verfahren zur Bestimmung des Magnesiumgehalts in Düngemittelextrakten mit Atomabsorptionsspektrometrie (AAS) fest. Dieses Verfahren gilt für nach CEN/TS 15960 und CEN/TS 15961 hergestellte EG-Düngemittelextrakte, für die die Angabe des Gesamtmagnesiums und/oder des wasserlöslichen Magnesiumgehalts vorgeschrieben ist, mit Ausnahme der folgenden Düngemittel nach Anhang I D [4], der sich auf mineralische Sekundär-nährstoffdünger bezieht:
- Typ 4 (Kieserit);
- Typ 5 (Magnesiumsulfat) und Typ 5.1 (Magnesiumsulfatlösung);
- Typ 7 (Kieserit mit Kaliumsulfat). Für diese Düngemittel gilt [4], Methode 8.8. ANMERKUNG Methode 8.8 ist in CEN/TS 16198 (siehe Literaturhinweise) enthalten. Das Verfahren gilt für alle Düngemittelextrakte, die Elemente in einer Menge enthalten, die eine komplexometrische Bestimmung von Magnesium stören könnten.

Engrais - Dosage du magnésium par spectrométrie d'absorption atomique

La présente Spécification technique spécifie une méthode de dosage du magnésium dans des extraits
d'échantillons d’engrais par spectrométrie d’absorption atomique (SAA).
Cette méthode est applicable aux extraits d'échantillons d’engrais CE obtenus conformément à la
CEN/TS 15960 et à la CEN/TS 15961, pour lesquels une déclaration de la teneur en magnésium total et/ou
hydrosoluble est requise, à l’exception des engrais suivants, selon l’Annexe I D de la référence
bibliographique [4] relative aux éléments nutritifs secondaires :
- type 4 (kiésérite) ;
- type 5 (sulfate de magnésium) et type 5.1 (solution de sulfate de magnésium) ;
- type 7 (kiésérite avec sulfate de potassium)
pour lesquels la méthode 8.8 de la référence bibliographique [4] s’applique.
NOTE La méthode 8.8 est abordée par la prCEN/TS 16198 (voir la Bibliographie).
La méthode s’applique à tous les extraits d'échantillons d’engrais contenant des éléments dans des quantités
susceptibles d’interférer avec le dosage complexométrique du magnésium.

Gnojila - Določevanje magnezija z atomsko absorpcijsko spektrometrijo

Ta tehnična specifikacija opredeljuje metodo določevanja vsebnosti magnezija v ekstraktih gnojil z uporabo atomske absorpcijske spektrometrije (AAS). Ta metoda velja za ekstrakte gnojil ES, pridobljene v skladu s CEN/TS 15960 in CEN/TS 15961, za katere je potrebna deklaracija o celotni vsebnosti magnezija in/ali vsebnosti v vodi topnega magnezija, razen naslednjih gnojil v skladu z dodatkom I D, ki se nanaša na sekundarna hranila: tip 4 (kiezerit); tip 5 (magnezijev sulfat) in tip 5.1 (raztopina magnezijevega sulfata); tip 7 (kiezerit s kalijevim sulfatom), za katerega se uporablja metoda 8.8.

This Technical Specification (CEN/TS) was approved by CEN on 5 March 2011 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, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
