The work of developing Inter- national Standards is carried out through IS0 technical committees. Every member body intereste

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 cir

International Standard IS0 2915 was developed by Technical Committee ISO/TC 20, Aircraft and space vehicles, and was circulated to the member bodies in May 1979. It has been approved by t
