The work of preparing International Standards is normally carried out through Iso technical committees. Each member body interested in a subject for which atechnical committee has been established has the righttobe 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 electrotechnical 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 2923 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 1, Noise. This second edition cancels and replaces the first edition (IS0 2923:1975), which has been technically revised. Annex A of this International Standard is for information only. @ISO1996 Alt rights reserved.
