The work of developing International Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been authorized 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. Information processing systems, and was circulated to the member bodies in February 1982. It has been approved by the member bodies of the following countries: Belgium Hungary South Africa, Rep. of Canada Italy Spain China Japan Sweden Czechoslovakia Netherlands Switzerland Norway Egypt, Arab Rep. of United Kingdom Poland France USA Germany, F.R.
