Price based on 1 page Foreword iso (the International Organization for Standardization) is a worldwide federation of national standards institutes (isO member bodies). The work of developing Inter- national Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. International organizations, governmentai 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. International Standard ISO 2412 was developed by Technical Committee ISO/TC 8, Shipbuilding and marine structures, and was circulated to the member bodies in May 1981. It has been approved by the member bodies of the following countries : Austria Germany, F.R. Portugal Belgium India Romania Brazil Italy Spain Bulgaria Korea, Dem. P.
