Price based on 4 pages Foreword Iso (the International Organization for Standardization) is a worldwide federation of national standards bodies (Iso member bodies). The work of preparing International Standards isnormally carried out throughisOtechnical committees.Eachmember bodyinterestedinasubjectforwhichatechnical committeehasbeenestablishedhas 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 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 % approvai by the member bodies voting. International Standard iSO 7384 was prepared by Technical Committee ISO/TC 156, Corrosion of metals and alloys. Users should note that all International Standards undergo revision from time to time arid that any reference made herein to any other international Standard implies its latest edition, unless otherwise stated. ?
