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

This European Standard specifies the methods used for the chemical analyses and the determination of physical properties of calcium carbonate, high-calcium lime and half-burnt dolomite used to treat water for human consumption.
This document describes the reference methods and, in certain cases, an alternative method which can be considered to be equivalent. In the case of a dispute, only the reference methods are used.
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.
NOTE   Schematic diagrams of the analyses are given in Annex A (Figures A.1 to A.4).

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

Diese Europäische Norm legt die Verfahren zur chemischen Analyse und zur Bestimmung von physikalischen Eigenschaften von Calciumcarbonat, Weißkalk, halb¬gebranntem Dolomit, Magnesiumoxid und Calcium-magnesiumcarbonat fest. Diese Stoffe werden zur Aufbereitung von Wasser für den menschlichen Gebrauch eingesetzt.
Diese Europäische Norm beschreibt Referenzprüfverfahren und in einigen Fällen Alternativprüfverfahren, die als gleichwertig angesehen werden können. Im Streitfall ist nur das Referenzverfahren maßgebend.
Werden andere Verfahren angewendet, so sind diese gegen die Referenzverfahren oder gegen international anerkannte Referenzmaterialien zu kalibrieren, um ihre Eignung nachzuweisen.
ANMERKUNG   Der Analysengang ist schematisch im Anhang A dargestellt (siehe Bilder A.1 bis A.6).

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

La présente Norme européenne décrit 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 et du carbonate de calcium et de magnésium utilisés pour le traitement de l’eau
destinée à la consommation humaine.
Le présent document décrit les méthodes de référence et, dans certains cas, une méthode alternative qui
peut être considérée comme étant équivalente. En cas de conflit, seules les méthodes de référence sont à
utiliser.
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.
NOTE Les représentations schématiques des analyses sont données à l’Annexe A (Figures A.1 à A.6).

Kemikalije, ki se uporabljajo za pripravo pitne vode - Kalcijev karbonat, visoko kalcijevo apno in polžgan dolomit, magnezijev oksid in kalcij-magnezijev karbonat - Preskusne metode

Ta evropski standard določa metode, ki se uporabljajo za kemične analize in določanje fizikalnih lastnosti kalcijevega karbonata, visokega kalcijevega apna in polžganega dolomita, ki se uporabljajo za pripravo pitne vode.
Ta dokument opisuje referenčne metode in v nekaterih primerih alternativno metodo, ki velja za enakovredno. V primeru spora se uporabljajo samo referenčne metode.
Druge metode se lahko uporabljajo, če so kalibrirane glede na referenčne metode ali glede na mednarodno sprejete referenčne materiale, kar je dokaz njihove enakovrednosti.
OPOMBA: Shematski diagrami analiz so podani v dodatku 1 (slike od A.1 do A.4).

The requirement values for free MgO and free Mg(OH)2 in half-burnt dolomite shall be expressed as free MgO in accordance with EN 1017. The same requirement is related to free CaO. The requirement value for MgO in magnesium oxide shall be expressed as MgO in dry substance in accordance with prEN 16004. Therefore, SIST EN 12485:2011

For the determination of the water-soluble content of high-calcium lime, the method in 6.5 is considered as the reference method. The sugar method described in 6.6 can be used as an alternative method if it is demonstrated that the results obtained with this method are equivalent to those of the reference method.
