National bodie

47、s that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other in

48、ternational organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the fied of information technology, IS0 and IEC have established a joint technical committee, ISOAEC JTC 1. Draft International Standards adopted by the joint technical committee

49、 are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 Oh of the national bodies casting a vote. International Standard ISO/IEC 10026-2 was prepared by Joint Technical Committee 1SO/IEC JTC 1, Information technology, Subcommittee SC 2 1, Open systems interconnection, data management and open distributed processing. This third edition cancels and replaces the second edition (ISO/lEC 10026-2:1996), which has been technically revised. This part of ISO/IEC 10026 is technically aligned with ITU-T Recommendation X.86
