Carbonate liming materials - Determination of reactivity - Automatic titration method with citric acid

This European Standard specifies a method for the determination of the reactivity of calcium carbonate and calcium magnesium carbonate liming materials. It assesses the speed and effectiveness of their neutralising potential by automatic titration with citric acid.
This method is applicable only to liming materials with a maximum particle size of 6,3 mm determined according to EN 12948.
NOTE   For marble dolomite (BET procedure according to ISO 9277 below 500 m2/kg), see EN 14984.

Carbonatische Kalke - Bestimmung der Reaktivität - Automatisches Titrationsverfahren mit Citronensäure

Diese Europäische Norm legt ein Verfahren für die Bestimmung der Reaktivität von Calciumcarbonat sowie carbonatischen Calcium-/Magnesium-Bodenverbesserungsmitteln fest. Die Geschwindigkeit und Wirksamkeit deren Neutralisationspotentials werden durch automatische Titration mit Citronensäure beurteilt.
Dieses Verfahren ist nur für Calcium-/Magnesium-Bodenverbesserungsmittel mit einer Korngröße von höchstens 6,3 mm, bestimmt nach EN 12948, anwendbar.
ANMERKUNG   Für Marmordolomit (BET-Verfahren nach ISO 9277 unter 500 m2/kg), siehe EN 14984.

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

La présente norme européenne spécifie une méthode de détermination de la réactivité des amendements minéraux basiques à base de carbonate de calcium ou à base de carbonate de calcium et de magnésium. Il évalue la rapidité et l'efficacité de leur potentiel de neutralisation par titration automatique à l'acide citrique.
Cette méthode s'applique uniquement aux amendements minéraux basiques ayant une taille de particules maximale de 6,3 mm déterminée selon l'EN 12948.
NOTE   Pour les dolomies d’origine métamorphique (de type marbre) (Procédure BET selon l’ISO 9277 en-dessous de 500 m²/kg), voir EN 14984.

Karbonatna sredstva za apnjenje - Določevanje reaktivnosti - Metoda avtomatske titracije s citronsko kislino

Ta evropski standard določa metodo za določevanje reaktivnosti sredstev za apnenje s kalcijevim karbonatom in kalcijevim magnezijevim karbonatom. Ugotavlja hitrost in učinkovitost njihovega nevtralizacijskega potenciala z avtomatsko titracijo s citronsko kislino. Ta metoda se uporablja samo za sredstva za apnenje z največjo velikostjo delcev 6,3 mm, ki je v skladu s standardom EN 12948.
