ISO (the International Organization for Standardization)
and IEC (the International Electrotechnical Commission) form the specialized
system for worldwide standardization. National bodies that are members
of ISO 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. ISO and IEC technical
committees collaborate in fields of mutual interest. Other international
organizations, 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 voting. Publication as an International Standard
requires approval by at least 75 % of the national bodies casting a vote.
International Standard ISO/IEC 8652 was prepared
by Joint Technical Committee ISO/IEC JTC 1, Information Technology.
