Copyright International Organization for Standardization Price based on 3 pages 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. Every member body interested in a subject for which a technical committee has been established has mental and non-governmental, in tiaison with IsO, also take part in the work. 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 member bodies voting. International Standard ISO 7245 Was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids.
