National bodies that are members of ISo orIEC participate in the development of International Standards through technical committees established by the respective 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. The procedures used to develop this document and those intended for its further maintenance are described in the ISo/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of document should be noted. (see www.iso.org/directives or www.iec.ch/members experts/refdocs). IEEE StandardsdocumentsaredevelopedwithinIEEE Societies and subcommittees ofIEEE Standards Association (IEEE SA) Board of Governors.IEEE develops its standards through anaccreditedconsensusdevelopmentprocess,whichbringstogethervolunteers representing varied viewpoints and interests to achieve the final product. IEEE standards are documents developed by volunteers with scientific, academic,and industry-based expertise in technical workinggroups.Volunteers are not necessarily members of IEEE or IEEE SA and participate without compensation from IEEE.While IEEE administers the process and establishes rulestopromotefairness in the consensus developmentprocess, IEEE does not independently evaluate,test, or verify theaccuracy of any of the information or the soundness of any judgments contained in its standards.
