Liming materials - Determination of the calcium content and magnesium content - Complexometric method
This European Standard 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% (m/m) 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 Calcium- und des Magnesiumgehaltes von Kalkdüngern fest.
Es gilt nicht für Produkte mit unter 2 % Massenanteil Magnesium, für Produkte mit über 1 % Massenanteil P2O5 und 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.
