Sanitary tapware - General specification for electrodeposited coatings of Ni-Cr

The aim of this European Standard is: - to define the condition of the exposed surfaces of tapware, - to establish the characteristics (resistance to corrosion, adherence) of the surface coating, - to describe the tests for verifying these characteristics. It applies to all sanitary fittings (supply or waste fittings) which have a metallic Ni-Cr coating, whatever the nature of the substrate material.

Sanitärarmaturen - Allgemeine Anorderungen für elektrolytische Ni-Cr-Überzüge

Diese Europäische Norm hat zum Ziel: - die Beschaffenheit von sichtbaren Oberflächen von Armaturen zu definieren, - die Anforderungen (Korrosionsbeständigkeit, Haftung) an diese Überzüge festzulegen, - die Prüfungen zu beschreiben, mit denen Beschaffenheit und Anforderungen überprüft werden können. Diese Norm gilt für alle Armaturen (Zulauf, Ablauf), die einen metallischen Ni-Cr-Überzug haben, unabhängig vom Grundwerkstoff.

Robinetterie sanitaire - Spécifications générales des revetements électrolytiques de Ni-Cr

La présente Norme européenne spécifie :
   l'état des surfaces apparentes des robinets ;
   les caractéristiques (résistance a la corrosion, adhérence) du revetement de surface ;
   les essais permettant de contrôler ces caractéristiques.
Elle s'applique a toutes les robinetteries sanitaires (alimentations ou vidage) ayant un revetement métallique Ni-Cr, quelle que soit la nature du support.
