The work of preparing International Standards is normally carried out. through IsO technical committees. Each memberbody interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non- governmental, in liaison with IsO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnicat standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 3822-4 was prepared by the European Committee for Standardization (CEN) in collaboration with ISO Technical Committee TC 43, Acoustics, Subcommittee SC 2, Building acoustics, in accordance with the Agreement on technical cooperation between IsO and CEN (Vienna Agreement). Thissecond edition cancels and replaces the : first edition (ISO 3822-4:1985), which has been technically revised. ISO 3822 consists of the following parts, under the general title Acoustics - Laboratory tests on noise emission from appliances and equipment used in water supply installations: Part 1: Method of measurement Part 2: Mounting and operating conditions for draw-off taps and mixing valves Part 3: Mounting and operating conditions for in-line valves and appliances Part 4: Mounting and operating conditions for special appliances Annexes A, B, C and D form an integral part of this part of ISO 3822.
