30、 worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of InternationaI Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collabor
31、ate in fields of mutua1 interest. Other international organizations, governmental and non- governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISOffEC JTC 1. Draft International Stand
32、ards 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.
