Fertilizers - Determination of magnesium by atomic absorption spectrometry

This European Standard 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 EN 15960 and EN 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 [2].
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 Europäische Norm legt ein Verfahren zur Bestimmung des Magnesiumgehalts in Düngemittelextrakten mit Atomabsorptionsspektrometrie (AAS) fest.
Dieses Verfahren gilt für nach EN 15960 und EN 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);
und mit Ausnahme der folgenden in [4], Anhang I A.3 gelisteten Düngemittel betreffend Kalidünger:
   Typ 7 (Kieserit mit Kaliumsulfat);
für diese Düngemittel gilt [4], Methode 8.8.
ANMERKUNG   Methode 8.8 entspricht EN 16198 [2].
Das Verfahren gilt für alle Düngemittelextrakte, die Elemente in einer Menge enthalten, die eine komplexo-metrische Bestimmung von Magnesium stören könnten.

Engrais - Dosage du magnésium par spectrométrie d'absorption atomique

La présente norme européenne 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 l’EN 15960 et à l’EN 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) ;
et à l’exception de l’engrais suivant figurant en Annexe I A.3 de la référence bibliographique [4] relatif aux engrais potassiques :
   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 l’EN 16198 [2].
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 evropski standard določa metodo za določevanje vsebnosti magnezija v ekstraktih gnojil z atomsko absorpcijsko spektrometrijo. Ta metoda se uporablja za ekstrakte gnojil ES, ki so bili pripravljeni v skladu s standardoma CEN/TS 15960 in CEN/TS 15961 in za katere se zahteva navedba skupne vsebnosti magnezija in/ali vsebnosti v vodi topnega magnezija, razen naslednjih gnojil iz stolpca [4] preglednice D Priloge I v zvezi s sekundarnimi hranili: – vrsta 4 (kizerit); – vrsta 5 (magnezijev sulfat) in vrsta 5.1 (raztopina magnezijevega sulfata); – vrsta 7 (kizerit s kalijevim sulfatom), za katere se uporablja točka [4] metode 8.8. Metoda se uporablja za vse ekstrakte gnojil, sestavljene iz elementov v količinah, ki bi lahko motile kompleksometrijsko določevanje magnezija.
