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. 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 member bodies voting.
