4、-Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is established when, in the judgement of the ANSI Board ofStandards Review, substantial agreement has

5、been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and objections be considered, and that a concerted effort be madetowards their resolution.The use of American Nation

Moreover, no person shall have the right or authority to issue aninterpretation of an American National Standard in the name of the AmericanNational Standards Institute. Requests for interp

19、EC 18372 and provides the text of that In-ternational Standard for use as the American National Standard. This standard wasdeveloped as an International Standard by ISO Committee 25 and reviewed and sub-mitted for approval as an American National Standard by the RapidIO(tm) Trade As-sociation. The f

20、oreword of the International Standard appears verbatim below.1) ISO (International Organization for Standardization) and IEC (International Elec-trotechnical Commission) form the specialized system for worldwide standardization.National bodies that are members of ISO or IEC participate in the develo

21、pment of In-ternational Standards through technical committees established by the respective or-ganization to deal with particular fields of technical activity. ISO and IEC technicalcommittees collaborate in fields of mutual interest. Other international organizations,governmental and non-government

22、al, in liaison with ISO and IEC, also take part inthe work.2) In the field of information technology, ISO and IEC have established a joint techni-cal committee, ISO/IEC JTC 1. Draft International Standards adopted by the jointtechnical committee are circulated to national bodies for voting. Publicat

23、ion as an In-ternational Standard requires approval by at least 75 % of the national bodies castinga vote.3) All users should ensure that they have the latest edition of this publication.4) No liability shall attach to IEC or ISO or its directors, employees, servants oragents including individual ex
