BS EN 1112:2008

This standard BS EN 1112:2008 Sanitary tapware. Shower outlets for sanitary tapware for water supply systems type 1 and type 2. General technical specification is classified in these ICS categories:

• 23.040.70 Hoses and hose assemblies

This European Standard specifies:

• the dimensional, leaktightness, mechanical, hydraulic and acoustic characteristics with which shower outlets shall comply;

• the procedures for testing these characteristics.

This European Standard applies to shower heads and hand showers 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 heads and hand showers connected downstream of the obturator of the tapware.

Integral and remote spray attachments incorporated in tapware (e.g. sink and wash basin mixing valves) are not covered by this standard.

Details of pressures and temperatures are given in Table 1.
