Influence of cementitious products on water intended for human consumption - Test methods - Part 3: Migration of substances from factory-made cementitious products

This European Standard specifies a method to determine the migration of substances from factory made cementitious products into test waters after contact with the products.
This European Standard is applicable to factory made cementitious products, e.g. cement mortar linings to metallic pipes, tanks, concrete pipes, etc., intended to be used for the transport and storage of water intended for human consumption, including raw water used for the production of drinking water.

Einfluss zementgebundener Produkte auf Wasser für den menschlichen Gebrauch - Prüfverfahren - Teil 3: Migration von Substanzen aus fabrikmäßig hergestellten zementgebundenen Produkten

Dieses Dokument legt ein Verfahren zur Bestimmung der Migration von Substanzen aus fabrikmäßig hergestellten zementgebundenen Produkten in Prüfwässer nach einem Kontakt mit den Produkten fest.
Dieses Dokument wird auf fabrikmäßig hergestellte zementgebundene Produkte angewendet, z. B. Zement-mörtelauskleidungen von metallischen Rohren, Behältern, Betonrohre usw., die dazu bestimmt sind, Wasser für den menschlichen Gebrauch zu transportieren und zu speichern, einschließlich Rohwasser, das für die Herstellung von Trinkwasser eingesetzt wird.
ANMERKUNG Prüfungen mit dem festgelegten Prüfwasser sind nicht unbedingt repräsentativ für Materialien, die in anderen Wasserarten und insbesondere in sehr weichem Wasser verwendet werden.

Influence des produits à base de ciment sur l'eau destinée à la consommation humaine - Méthodes d'essai - Partie 3 : Migration de substances à partir des produits fabriqués en usine

La présente Norme européenne spécifie une méthode permettant de déterminer la migration des substances issues de produits à base de ciment fabriqués en usine dans les eaux d'essai après contact avec les produits concernés.
La présente Norme européenne s'applique aux produits à base de ciment fabriqués en usine, tels que les revêtements intérieurs de mortier de ciment appliqués sur des tubes métalliques, des réservoirs, des tubes en béton, etc., destinés à être utilisés pour le transport et le stockage de l'eau destinée à la consommation humaine, y compris l'eau brute utilisée pour la production de l'eau potable.
