Influence of cementitious products on water intended for human consumption - Test methods - Part 1: Influence of migration from factory made cementitious products on the organoleptic parameters
This European Standard specifies a method to determine the influence of factory made cementitious products on the odour, flavour, colour and turbidity of 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 for human consumption, including raw water used for the production of drinking water.
Einfluss zementgebundener Produkte auf Wasser für den menschlichen Gebrauch - Prüfverfahren - Teil 1: Einfluss fabrikmäßig hergestellter zementgebundener Produkte auf organoleptische Parameter und Migration von organischen Substanzen (TOC)
Dieses Dokument legt ein Verfahren zur Bestimmung des Einflusses fabrikmäßig hergestellter zement-gebundener Produkte auf Geruch, Geschmack, Färbung, Trübung und den gesamten organischen Kohlenstoff (TOC) von Prüfwässern nach einem Kontakt mit den Produkten fest.
Dieses Dokument wird auf fabrikmäßig hergestellte zementgebundene Produkte angewendet, z. B. Zement-mörtelauskleidungen von metallischen Rohren, Behälter, Betonrohre usw., die dazu bestimmt sind, Trink-wasser zu transportieren und aufzubewahren, einschließlich Rohwasser, das für die Herstellung von Trink-wasser 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 1 : Influence sur les paramètres organoleptiques et migration de substances organiques à partir des produits fabriqués en usine
La présente Norme européenne spécifie une méthode permettant de déterminer l'influence des produits à base de ciment fabriqués en usine sur l'odeur, la flaveur, la couleur, la turbidité et la teneur en carbone organique total (COT) des 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.
