(Main)Sanitary tapware - Automatic shut-off valves PN 10
Sanitary tapware - Automatic shut-off valves PN 10
This European Standard is applicable to single and mixer taps with automatic shut-off for use with
sanitary appliances installed in washrooms.
It does not apply to urinal or WC flushing valves or valves which open automatically.
The purpose of this standard is to specify the marking, identification, chemical/hygiene, dimensional,
leaktightness, pressure resistance, hydraulic, mechanical endurance, and acoustical characteristics of
automatic shut-off tapware.
The tests described in all the standard are type tests (laboratory tests) and not quality control tests
carried out during manufacture.
Sanitärarmaturen - Selbstschlussarmaturen PN 10
Diese Europäische Norm gilt für selbstschließende Auslaufventile und Mischbatterien für die Ausrüstung von Sanitärausstattungsgegenständen, die in den der Hygiene dienenden Räumen (Waschräumen) installiert werden.
Sie gilt nicht für Urinal- und WC-Spüler und nicht für selbsttätig öffnende Armaturen.
Die Norm hat den Zweck, die Kennzeichnung, Identifizierung, chemische und hygienische Anforderungen, Maße, Dichtheit, Druckfestigkeit, hydraulische Anforderungen, mechanische Dauerfestigkeit und Geräusch¬verhalten von Selbstschlussarmaturen festzulegen.
