IS0 (the International Organization for Standardization) is a worldwide federation of national standards institutes (IS0 member bodies) The work of developing Inter- national Standards is carried out through IS0 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 IS0 Council
International Standard IS0 1035/Z was developed by Technical Committee ISO/TC 17, Steel, and was circulated to the member bodies in December 1978
It has been approved by the member bodies of the following countries :
