- This part of ISO 3822 specifies the mounting and operating conditions to be used for draw-off taps when measuring noise emission resulting from water flow. The procedures described are for general use for all types of draw-off taps of conventional design. The mounting and operating conditions apply to complete draw-off tap assemblies, including any components normally supplied with the taps (such as shower hoses with heads, antisplash nozzles, strainers, aerators and S-couplings or other units). The mounting and operating conditions for individual components are outside the scope of this part of ISO 3822. NOTE — When components are interchangeable, they may be tested separately in accordance with the procedures specif ied in other parts of this International Standard. Thermostatic mixing devices, 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 and are not covered by this part of ISO 3822. Similarly, electrically operated valves are regarded as combined devices (solenoid valve and outlet) and are not covered by this part of ISO 3822. The test procedures cover a range of flow pressures between 0,1 and 0,5 MPa1), of which the most common value is 0,3 MPa. When the components mentioned are interchangeable or removable without disturbing the normal function of the appliance, tests may be carried out in which these components or flow resistances are replaced by specified standard components or standard flow resistances.
