Carbonate liming materials - Determination of reactivity - Potentiometric titration method with hydrochloric acid

This European Standard specifies a method for the determination of the speed and effectiveness of the neutralizing potential of calcium carbonate and calcium magnesium carbonate liming materials by potentiometric titration with hydrochloric acid.
This method is applicable only to liming materials with a maximum particle size of 6,3 mm.
NOTE   The type of liming material should be identified according to EN 14069 and the particle size should be determined according to EN 12948.

Carbonatische Kalke - Bestimmung der Reaktivität - Potentiometrisches Titrationsverfahren mit Salzsäure

Diese Europäische Norm legt ein Verfahren für die Bestimmung der Geschwindigkeit und Wirksamkeit des
Neutralisationspotentials von Calciumcarbonat und carbonatischen Calcium-Magnesiumkalken durch
potentiometrische Titration mit Salzsäure fest.
Dieses Verfahren gilt nur für Calcium-/Magnesium-Bodenverbesserungsmittel mit einer Korngröße von
höchstens 6,3 mm.
ANMERKUNG Der Typ des Calcium-/Magnesium-Bodenverbesserungsmittels sollte nach EN 14069 identifiziert und
die Korngröße nach EN 12948 bestimmt werden.

Amendements minéraux basiques carbonatés - Détermination de la réactivité - Méthode par titration potentiométrique à l'acide chlorhydrique

La présente norme spécifie une méthode pour déterminer la vitesse et l'efficacité du potentiel de
neutralisation des carbonates de calcium et carbonates de calcium et de magnésium, utilisés comme
amendements minéraux basiques, par titration potentiométrique à l’acide chlorhydrique.
La présente méthode s'applique seulement aux amendements minéraux basiques dont les particules ne
dépassent pas 6,3 mm.
NOTE Il conviendrait d’identifier le type d’amendement minéral basique, selon la norme EN 14069 et la taille des
particules devrait être déterminée selon la norme EN 12948.
