Other internationa l 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 IE
33、C 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 Standards adopted by the j
34、oint technical committee are circulated to national bodies for voting. Publication asan International Standard requires approval byat least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights
