IsO and IEc technical 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 through a consensus development process, approved by the American National Standards Institute, which process and establishes rules to promote fairness in the consensus development process, the IEEE does not independentlyevaluate,test,orverifytheaccuracyofanyoftheinformationcontainedinitsstandards bythejoint technical committee are circulatedtonational bodies for voting.Publication asanInternational 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 coveredbypatentrights.Bypublicationofthisstandard,nopositionistakenwithrespecttotheexistenceor validityof anypatentrightsinconnectiontherewith.IsO/EEEisnotresponsibleforidentifyingessential patents or patent claims for which a license may be required, for conducting inquiries into the legal validity or scope of patents or patent claims or determining whether any licensing terms or conditions provided in connection with submission of a Letter of Assurance or a Patent Statement and Licensing Declaration Form, if advised that determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility.
