ISO and IEC tec

Other international organizations, governmental and non-governmental, inliaison 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.The

43、main task of technical committees is to prepare International Standards, but in exceptional circumstances atechnical committee may propose the publication of a Technical Report of one of the following types:Gbe type 1, when the required support cannot be obtained for the publication of an Internatio
