2、al of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been

3、 reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The use of American Nation

This document is identical to ISO/IEC 9593- 4:1991/Amd. 1:1994 and the followin

22、g three paragraphs are the original foreword as it appeared in that document.) IS0 (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC pa

23、rticipate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical commit- tees collaborate in fields of mutual interest. Other international organiza- tions, gove

24、rnmental 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, ISO/IEC JTC 1. Draft International Standards adopt- ed by the joint technical committee are circulated to national

25、 bodies for voting. Publication as an International Standard requires approval by at least 75% of the national bodies casting a vote. Amendment 1 to International Standard ISO/IEC 9593-4991 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology. Requests for interpretation,

26、suggestions for improvement or addenda, or defect reports are welcome. They should be sent to the X3 Secretariat, Computer and Business Equipment Manufacturers Association, 1250 Eye Street, NW, Suite 200, Washington, DC 20005. This standard was processed and approved for submittal to ANSI by Accredi

27、ted Standards Committee on Information Technology, X3. Committee approval of the standard does not necessarily imply that all committee members voted for its approval.
