Influence of organic materials on water intended for human consumption - Determination of the chlorine demand - Test method

This European Standard specifies a method for determining the chlorine demand of organic materials intended for use in contact with drinking water.
This European Standard is applicable to factory made and site applied products used for the distribution, transport and storage of drinking water.
This European Standard does not cover the use of high levels of chlorine to disinfect products when they are put into service.

Einfluss organischer Materialien auf Wasser für den menschlichen Gebrauch - Bestimmung der Chlorzehrung - Prüfverfahren

Diese Europäische Norm legt ein Verfahren zur Bestimmung der Chlorzehrung von Bedarfsgegenständen aus organischen Materialien fest, die für den Gebrauch im Kontakt mit Trinkwasser vorgesehen sind.
Diese Norm ist anwendbar auf fabrikmäßig und auf vor Ort hergestellte Produkte, die zur Verteilung, zum Transport und zur Speicherung von Trinkwasser dienen.
Diese Norm behandelt nicht den Einsatz hoher Chlorkonzentrationen für die Desinfektion von Produkten vor ihrem Einsatz.

Influence des matériaux organiques sur l'eau destinée à la consommation humaine - Détermination de la demande en chlore - Méthode d'essai

La présente Norme européenne spécifie une méthode de détermination de la demande en chlore des matériaux organiques destinés à entrer en contact avec l’eau potable.
Elle s’applique aux produits fabriqués en usine et aux produits appliqués sur site, utilisés pour la distribution, le transport et le stockage de l’eau potable.
Elle ne traite pas de l’utilisation de chlore à des niveaux élevés pour désinfecter les produits lorsque ces derniers sont mis en service.

Note 1 to entry: In this context, the product is the final prepared surface that comes into contact with water. 4 Principle Initially test pieces are pre-conditioned by washing and rinsing procedures. Test pieces are then completely filled with or immersed in test water. This filling or immersion procedure is carried out three times on the same test pieces under specified conditions. After each contact period the contact water is immediately analysed to determine the residual content of free chlorine. Blank tests without test pieces are undertaken with the same test water to obtain blank water results. NOTE If the reduction in the free-chlorine concentration o
