It does not apply to no-contact detection valves. It is intended to specify  marking and identification, physico-chemical, dimensional, leaktightness, pressure behaviour, hydraulic, mechanical endurance and acoustic characteristics of ing valves for WCs and urinals with automatic closure ;  test s used to verify these characteristics ;  and to determine requirements for the atmospheric interrupter which shall be an integral part of the WC ing valve. It applies in the following pressure and temperature conditions Table 1 Conditions of use for tapware Urinals WC DN 15 WC DN 20 0,1 MPa ≤ P ≤ 0,4 MPa 1 bar ≤ P ≤ 4 bar WC DN 25 0,08 MPa ≤ P ≤ 0,25 MPa 0,8 bar ≤ P ≤ 2,5 bar Dynamic Pressure range recommended for a good working WC DN 32 0,08 MPa ≤ P ≤ 0,2 MPa 0,8 bar ≤ P ≤ 2 bar Maximum static pressure1 MPa 10 bar Water temperature≤ 25 C 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
