Iso collaborates closely with the International Electrotechnical Commission (IEC)on all matters ofelectrotechnical standardization. Theprocedures used to developthis documentand those intended for its further maintenancearedescribed in theIso/IEc Directives, Part 1.In particular, the different approval criteria needed for the different types of Iso document should be noted (see www.iso.org/directives). IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA)Standards Board.TheIEEE develops its standards through a consensus developmentprocess,approvedbytheAmericanNational Standards Institute,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 administerstheprocess and establishesrulestopromotefairnessintheconsensusdevelopmentprocess,the IEEE does not independentlyevaluate,test, or verify the accuracy of any of the information contained in its standards.
