Sanitary tapware. Shower hoses for sanitary tapware for water supply systems of type 1 and type 2. General technical specification. | Status: Revised, Superseded, Withdrawn

1 Scope This European Standard specifies:

• — the dimensional, leaktightness, mechanical and hydraulic characteristics with which shower hoses shall comply;
• — the procedures for testing these characteristics.

This European Standard applies to shower hoses of any material used for ablutionary purposes and intended for equipping and supplementing sanitary tapware for baths and showers. This European Standard applies to shower hoses connected downstream of the obturator of the tapware. Hoses which are an integral part of sanitary tapware (sink and wash basin mixing valves) or hoses intended to connect sanitary tapware to the water supplies are not covered by this European Standard. Details of pressures and temperatures are given in Table 1.
