Fertilizers - Manganimetric determination of extracted calcium following precipitation in the form of oxalate

This European Standard specifies a manganimetric method for the determination of the calcium content in fertilizer extracts.
This method is applicable to EC fertilizers for which a declaration of the total and/or water-soluble calcium content is provided for in Regulation (EC) No 2003/2003, Annex I [3].

Düngemittel - Manganometrische Bestimmung von Calcium nach Oxalatfällung

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Calciumgehalts in Dünge¬mittel¬extrakten fest.
Dieses Verfahren gilt für EG-Düngemittel, für die die Verordnung (EG) Nr. 2003/2003, Anhang I [3] die Angabe des gesamten und/oder des wasserlöslichen Calciumgehalts vorschreibt.

Engrais - Dosage manganimétrique du calcium extrait après précipitation sous forme d'oxalate

La présente norme européenne spécifie une méthode de dosage manganimétrique du calcium dans des solutions d’extraction d’engrais.
Cette méthode est applicable aux engrais CE pour lesquels une déclaration de la teneur en calcium total et/ou soluble dans l’eau est prévue dans le Règlement (CE) n° 2003/2003, Annexe I [3].

Gnojila - Manganometrijsko določevanje ekstrahiranega kalcija po obarjanju v obliki oksalata
