Water conditioning equipment inside buildings - Electrolytic treatment systems with aluminium anodes - Requirements for performance, safety and testing
This European Standard applies to electrolytic dosing systems for conditioning water intended for human consumption inside buildings and based on dissolution of aluminium anodes (with imposed DC current). It specifies constructional (but not dimensional) and operational requirements. It describes relevant methods for testing performance and safety. It only concerns units which are permanently connected to the mains supply.
Anlagen zur Behandlung von Trinkwasser innerhalb von Gebäuden - Elektrolytische Dosierungsanlagen mit Aluminiumanoden - Anforderungen an Ausführung und Sicherheit, Prüfung
Diese Europäische Norm gilt für elektrolytische Dosierungsanlagen zur Behandlung von Wasser für den menschlichen Gebrauch innerhalb von Gebäuden und hat das Inlösunggehen von Aluminiumanoden (bei aufgeprägtem Gleichstrom) zur Grundlage. In dieser Norm werden die Anforderungen im Hinblick auf die Bauausführung (jedoch nicht die Maße) und den Betrieb festgelegt. Sie beschreibt die relevanten Verfahren zur Prüfung von Eigenschaften und Sicherheit. Sie bezieht sich nur auf in die Trinkwasser-Installation fest eingebaute Anlagen.
Appareils de conditionnement d'eau a l'intérieur des bâtiments - Installations électrolytiques avec anodes en aluminium - Exigences de performances, de sécurité et d'essais
La présente norme européenne s'applique aux installations de traitement électrolytique utilisées pour le conditionnement de l'eau destinée a la consommation humaine a l'intérieur des bâtiments et dont le fonctionnement repose sur la dissolution des anodes en aluminium (par courant continu imposé). Elle spécifie les exigences en matiere de construction (mais pas les dimensions) et de fonctionnement. Elle décrit les méthodes appropriées permettant de procéder aux essais de performance et de sécurité. Elle concerne uniquement les appareils reliés en permanence au réseau.
