Chemicals used for treatment of water intended for human consumption - Calcium carbonate, high-calcium lime, half-burnt dolomite, magnesium oxide, calcium magnesium carbonate and dolomitic lime - Test methods

This document specifies the methods used for the chemical analyses and the determination of physical properties of calcium carbonate, high-calcium lime, half-burnt dolomite, magnesium oxide, calcium magnesium carbonate and dolomitic lime used to treat water for human consumption.
This document specifies the reference methods and, in certain cases, an alternative method which can be considered to be equivalent.
Any other methods may be used provided they are calibrated, either against the reference methods or against internationally accepted reference materials, in order to demonstrate their equivalence.

Produkte zur Aufbereitung von Wasser für den menschlichen Gebrauch - Calciumcarbonat, Weißkalk, halbgebrannter Dolomit, Magnesiumoxid, Calciummagnesiumcarbonat und Dolomitkalk - Prüfverfahren

Dieses Dokument legt die Verfahren für die chemischen Analysen und zur Bestimmung von physikalischen Eigenschaften von Calciumcarbonat, Weißkalk, halbgebranntem Dolomit, Magnesiumoxid, Calciummagnesiumcarbonat und Dolomitkalk zur Aufbereitung von Wasser für den menschlichen Gebrauch fest.
Dieses Dokument legt die Referenzverfahren und in einigen Fällen ein Alternativverfahren, das als gleichwertig angesehen werden kann, fest.
Andere Verfahren dürfen unter der Voraussetzung angewendet werden, dass diese gegen die Referenzverfahren oder gegen international anerkannte Referenzmaterialien kalibriert sind, um ihre Gleichwertigkeit nachzuweisen.

Produits chimiques utilisés pour le traitement de l'eau destinée à la consommation humaine - Carbonate de calcium, chaux, dolomie semi-calcinée, oxyde de magnésium, carbonate de calcium et de magnésium et chaux dolomitique - Méthodes d'essai

Le présent document spécifie les méthodes utilisées pour réaliser les analyses chimiques et déterminer les propriétés physiques du carbonate de calcium, de la chaux, et de la dolomie semi-calcinée, de l’oxyde de magnésium, du carbonate de calcium et de magnésium et de la chaux dolomitique utilisés pour le traitement de l’eau destinée à la consommation humaine.
Le présent document spécifie les méthodes de référence et, dans certains cas, une méthode alternative qui peut être considérée comme étant équivalente.
D’autres méthodes peuvent être utilisées, dans la mesure où elles sont étalonnées, soit par rapport aux méthodes de référence, soit par rapport aux matériaux de référence internationalement reconnus, de manière à démontrer leur équivalence.
