National bodies that are members of ISOorTECparticipateinthedevelopmentofInternationalStandardsthroughtechnicalcommittees establishedbytherespectiveorganizationtodealwithparticularfieldsoftechnicalactivity.ISOandTEC 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. InternationalStandardsaredraftedinaccordancewiththerulesgivenintheISO/lECDirectives,Part2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as ISO/IEC 28361 was prepared by Ecma International (as ECMA-373) and was adopted, under a special "fast- track procedure", by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC. ional Organization for Standardization @ ISO/IEC 2007 - All rights reserved ISO/IEC 28361:2007(E) Introduction International, this International Standard spe
