This part of EN ISO 3822 specifies the mounting and operating conditions to be used for draw-off taps and mixing valves when measuring noise emission resulting from water flow. The procedures described are for general use for all types of draw-off taps and mixing valves of conven-tional design, with a recommended flow pressure range of 0,1 MPa to 0,5 MPa. The mounting and operating conditions apply to draw-off tap and mixing valve assemblies including any inlet or outlet mounting or installation unions, elbows, adaptors, etc., but excluding interchangeable outlet accessories such as aerators, shower hoses, shower heads, flow straighteners, etc. These outlet access-cries are replaced by standardized low-noise flow resistances. When the outlet accessories mentioned above are neither interchangeable nor removable, then the tests are carried out with them in place. Interchangeable outlet accessories are tested separately according to procedures specified in other parts of EN ISO 3822. Thermostatic mixing valves, intended for use with more than one independent draw-off tap, and bidet valves with a direct outlet into an interior part of the body of the bidet are not regarded as conventional draw-off taps or mixing valves and are not covered by this part of EN ISO 3822. Similarly, electrically operated valves are regarded as combined devices (solenoid valve and outlet) and are not covered by this part of EN ISO 3822. The test procedures cover a range of flow pressures between 0,1 MPa and 0,5 MPa. n ote:1) 1 MPa = 10 bar
