44、tion for Standardization) and IEC (theInternational Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of InternationalStandards through technical committees established by the respecti
45、ve organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
46、technology, ISO and IEC have established a joint technical committee, ISO/IECJTC1. Draft InternationalStandards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an InternationalStandard requires approval by at least75% of the national bodies casti
47、ng a vote. InternationalStandard ISO/IEC10885 was prepared by Joint Technical Committee ISO/IECJTC1, Information technology, Sub-Committee SC23, Optical disk cartridges for information interchange. Annex A, Annex C, Annex D, Annex E, Annex F, Annex G, Annex H, Annex J, Annex K, Annex L, Annex M, Ann
