Defines a method of measurement, in the laboratory, of the noise emission resulting from the flow of water through appliances and equipment used in water supply installations. The items covered include draw-off taps, in-line valves and special appliances, for example pressure reducers and water-heating appliances, all of which are hereafter referred to as "appliances". The method specified makes it possible to obtain comparable results of measurements in different laboratories.
