Liming materials - Determination of the calcium content and magnesium content - Complexometric method

TThis document specifies a complexometric method for the determination of the calcium content and the magnesium content of liming materials.
It is not applicable to products with a mass fraction less than 2 % magnesium or those with a mass fraction more than 1 % P2O5 and is not applicable to silicate liming materials.

Kalkdünger - Bestimmung des Calcium- und Magnesiumgehaltes - Komplexometrisches Verfahren

Dieses Dokument legt ein komplexometrisches Verfahren zur Bestimmung des Calciumgehaltes und des Magnesiumgehaltes von Kalkdüngern fest.
Es ist nicht anwendbar für Produkte mit unter 2 % Massenanteil Magnesium, für Produkte mit über 1 % Massenanteil P2O5 und ist nicht anwendbar für Kalke aus Eisenhüttenschlacken.

Amendements minéraux basiques - Détermination de la teneur en calcium et de la teneur en magnésium - Méthode par complexométrie

Le présent document spécifie une méthode de détermination, par complexométrie, de la teneur en calcium et de la teneur en magnésium des amendements minéraux basiques.
Elle ne s'applique pas aux produits ayant une fraction massique inférieure à 2 % de magnésium, ni aux produits ayant une fraction massique supérieure à 1 % de P2O5, ni aux amendements minéraux basiques silicatés.
