Price based on 20 pages without license from IHS Not for Resale Foreword ISo (the International Organization for Standardization) is a worldwide federation of national standards bodies (isO member bodies). The work of preparing International Standards is normally carried out through IsO technicat 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. Draft International Standards adopted by the technical committees are circutated to the member bodies for approval before their acceptance as International Standards by the ISo Councit. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting.

For the purpose of this International Standard, the following definitions apply.
