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 represented on that committee. International organizations, govern- mental 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 approval before their acceptance as International Standards by the Iso' Council. They are approved in accordance with Iso procedures requiring at least 75 % approval by the memberbodies voting. International Standard Iso 3469 was prepared by Technical Committee IsO/Tc 22,Roadvehicles. This second edition cancels and replaces the first edition (ISO 3 3469:1975), of which it constitutes a technical revision and expan- sion. Annexes A and B and C form an integral part of this International Standard. Annex D is for information only. ?IsO 1989 All rights reserved.
