Fertilizers - Determination of ammoniacal nitrogen

This European Standard specifies a method for the determination of the ammoniacal nitrogen content in fertilizers. The method is applicable to all nitrogenous fertilizers including compound fertilizers, in which nitrogen is found exclusively either in the form of ammonium salts or ammonium salts together with nitrates.
This European Standard is not applicable to fertilizers containing urea, cyanamide or other organic nitrogenous compounds.

Düngemittel - Bestimmung von Ammoniumstickstoff

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Ammoniumstickstoffgehalts in Düngemitteln fest. Das Verfahren ist auf alle Stickstoffdünger einschließlich Mehrnährstoffdünger anwendbar, in denen Stickstoff ausschließlich entweder in Form von Ammoniumsalzen oder von Ammoniumsalzen zusammen mit Nitraten enthalten ist.
Diese Europäische Norm gilt nicht für Düngemittel, die Harnstoffe, Cyanamid oder andere organische Stick-stoffverbindungen enthalten.

Engrais - Détermination de l'azote ammoniacal

La présente Norme européenne spécifie une méthode permettant de doser la teneur en azote ammoniacal
dans les engrais. La méthode est applicable à tous les engrais azotés, y compris les engrais composés, dans
lesquels l’azote se trouve exclusivement sous forme de sels d’ammonium ou de sels d’ammonium associés à
des nitrates.
La présente Norme européenne ne s'applique pas aux engrais contenant de l'urée, de la cyanamide ou
d’autres composés organiques azotés.
