BS EN 1112:2008

Defines the dimensional, leaktightness, mechanical, hydraulic and acoustic characteristics with which shower outlets shall comply and the procedures for testing these characteristics.

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.
