Influence of cementitious products on water intended for human consumption - Test methods - Part 3: Migration of substances from factory-made cementititous 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 von zementgebundenen Produkten auf Wasser für den menschlichen Gebrauch - Prüfverfahren - Teil 3: Migration von Substanzen aus fabrikmäßig hergestellten zementgebundenen Produkten
Diese Europäische Norm legt ein Verfahren zur Bestimmung der Migration von Substanzen aus fabrikmäßig hergestellten zementgebundenen Produkten in Prüfwässer nach einem Kontakt mit den Produkten fest.
Diese Europäische Norm gilt für fabrikmäßig hergestellte zementgebundene Produkte, z. B. Zementmörtel-auskleidungen von metallischen Rohren, Behältern, Betonrohre usw., welche dazu bestimmt sind, Trinkwasser zu transportieren und zu speichern, einschließlich Rohwasser, welches für die Herstellung von Trinkwasser eingesetzt wird.
Influence des produits à base de ciment sur l'eau destinée à la consommation humaine - Méthodes d'essais - 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.
