The work of preparing International Standards is normally carried out through IsO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be rep- resented 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 Interna- tional Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 7960 was prepared by Technical Committee ISo/Tc 39, Machine tools, Subcommittee SC 6, Noise of machine tools andISO/TC 43, Acoustics. Annexes A to H, J to N and P to U form an integral part of this Interna- tional Standard. Annex V is for information only CISO1995 All rights reserved.
