Fertilizers - Determination of molybdenum in concentrations ≤ 10 % using spectrometry of a complex with ammonium thiocyanate

This European Standard specifies a method for determination of total and water extractable molybdenum in mineral fertilizers containing less than or equal to 10 % molybdenum.
This method is applicable to water and aqua regia fertilizer extracts obtained according to EN 16962 and/or EN 16964.

Düngemittel - Bestimmung von Molybdän in Konzentrationen ≤ 10 % durch Spektrometrie eines Komplexes mit Ammoniumthiocyanat

Diese Europäische Norm legt ein Verfahren zur Bestimmung von Gesamtmolybdän und von wasserextrahierbarem Molybdän in mineralischen Düngemitteln, die weniger als oder gleich 10 % Molybdän enthalten, fest.
Dieses Verfahren ist auf Wasser  und Königswasser Extrakte von Düngemitteln anwendbar, die nach EN 16962 und/oder EN 16964 erhalten wurden.

Engrais - Dosage du molybdène dans des concentrations ≤ 10 % par spectrométrie d'un complexe avec du thiocyanate d'ammonium

La présente Norme européenne spécifie une méthode pour le dosage du molybdène total et du molybdène extractible à l’eau dans des engrais minéraux contenant au plus 10 % de molybdène.
Cette méthode est applicable aux extraits d’engrais aqueux et à l’eau régale obtenus conformément à l’EN 16962 et/ou à l’EN 16964.

Gnojila - Določevanje molibdena v koncentracijah, manjših ali enakih 10 %, s spektrometrijo kompleksa z amonijevim tiocianatom

Ta dokument določa postopek za določevanje skupne vsebnosti molibdena in molibdena, ki ga je mogoče ekstrahirati z vodo, v mineralnih gnojilih, ki vsebujejo manj kot oziroma 10 % molibdena. Metode ekstrahiranja so določene v standardu EN 260172 in/ali EN 260176.
