The work of developing Interna- tional 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, governmental 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 4089 was developed by Technical Committee ISO/TC 8, Shipbuilding, and was circulated to the member bodies in February 1977. France Austria Poland Belgium Germany, F. R.
