Iso and IEC technical committeescollaborateinfieldsofmutualinterest.Otherinternationalorganizations,governmentalandnon 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. IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards throughaconsensusdevelopmentprocess,approvedbytheAmericanNationalStandardsInstitute,which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, the IEEE does not independentlyevaluate,test,orverifytheaccuracyofanyoftheinformationcontainedinitsstandards. The main task of ISO/IEC JTC 1 is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is called to the possibility that implementation of this standard may require the use of subject matter covered by patent rights. By publication of this standard, no position is taken with respect to the existence or validity of any patent rights in connection therewith. ISo/IEEE is not responsible for identifying essential patents or patent claims for which a license may be required, for conducting inquiriesintothelegalvalidityorscopeofpatentsorpatentclaimsordeterminingwhetherany licensing terms or conditions provided in connection with submission of a Letter of Assurance or a Patent Statement and Licensing Declaration Form, if any, or in any licensing agreements are reasonable or non-discriminatory.
