BS EN 16146:2012+A1:2014

This European Standard applies to hoses for extractable outlets of any material intended for equipping sanitary tapware for sinks and basins. Such hoses will only be connected downstream of the obturator of the tapware. The tapware will comply with EN200 , EN817 , EN1111 , EN1286 or EN1287 (see [1], [2], [3], [5] and [6]). Hoses intended to connect sanitary tapware to the water supplies are not covered by this standard. This European Standard specifies: the dimensional, mechanical and hydraulic characteristics with which the hose for extractable outlets shall comply; the procedures for testing these characteristics. Details of pressures and temperatures are given in Table1.
