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 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 6586 was developed by Technical Committee ISO/TC 97 Computers and information processing, and was circulated to the member bodies in November 1979. Australia Germany, F. R.
