National bodies that are members of ISsO or TECF participate in the development of International Standards through with particular fields of technical activity. ISO and IEc technical com- izations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, isO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for vot ing. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. International Standard ISO/IEC 13575 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 6. Telecommunications and information exchange between systems.
