CEN/TC 126/WG 3 - Laboratory test on noise from hydraulic equipment used in water installations

This part of EN ISO 3822 specifies 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.

Gives the mounting and operating conditions to be used for a number of in-line valves and appliances, when measuring the noise emission resulting from water flow. Replaces the first edition.

Describes the mounting and operating conditions to be used for draw-off taps and mixing valves when measuring noise emmission resulting from water flow. Replaces the first edition, which has been technically revised.

Gives the mounting and operating conditions to be used for in-line valves and appliances, which control the flow, pressure or temperature of the water in water supply installations, when measuring the noise emission resulting from water flow. Replaces the first edition.
