Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information t
10、echnology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Stan

Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.
