Carbonate and silicate 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 neutralising potential of calcium carbonate, calcium magnesium carbonate and calcium magnesium silicate 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 und silikatische 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 sowie carbonatischen und silikatischen Calcium /Magnesium-Bodenverbesserungsmitteln (Kalkdüngern) durch potentiometrische Titration mit Salzsäure fest.
Dieses Verfahren gilt nur für Calcium-/Magnesium-Bodenverbesserungsmittel mit einer Korngröße von höchstens 6,3 mm.
Der Typ des Calcium-/Magnesium-Bodenverbesserungsmittels sollte nach EN 14069 identifiziert und die Korngröße nach EN 12948 bestimmt werden.

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

La présente Norme européenne spécifie une méthode pour déterminer la vitesse et l'efficacité du potentiel de neutralisation des carbonates de calcium, carbonates de calcium et de magnésium et silicates de calcium et de magnésium utilisés comme amendements minéraux basiques, par titrage potentiométrique à l’acide chlorhydrique.
La présente méthode s'applique seulement aux amendements minéraux basiques dont la taille des particules ne dépasse pas 6,3 mm.
Le type d’amendement minéral basique doit être identifié conformément à l’EN 14069 et la taille des particules doit être déterminée conformément à l’EN 12948.

Karbonatna in silikatna sredstva za apnjenje - Določevanje reaktivnosti - Potenciometrijska titracijska metoda s klorovodikovo kislino

Ta evropski standard določa metodo za ugotavljanje hitrosti in učinkovitosti nevtralizacijskega potenciala sredstev za apnenje s kalcijevim karbonatom, kalcijevim magnezijevim karbonatom in kalcijevim magnezijevim silikatom s potenciometrijsko titracijo s klorovodikovo kislino. Ta metoda se uporablja le za sredstva za apnenje z največjo velikostjo delcev 6,3 mm. Vrsta sredstva za apnenje naj bi se opredelila v skladu s standardom EN 14069, velikost delcev pa v skladu s standardom EN 12948.
