IEEE Standards documents are developed within the mittees of the IEEE Societies and the Standards
mittees of the IEEE Standards Board. Members of mittees serve voluntarily and without
compensation. They are not necessarily members of the Institute. The standards developed within IEEE represent a
consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE which
have expressed an interest in participating in the development of the standard.
Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other
ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE
Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change
brought about through developments in the state of the art ments received from users of the standard. Every
IEEE Standard is subjected to review at least once every five years for revision or reaffirmation. When a document is
more than five years old, and has not been reaffirmed, it is reasonable to conclude that its contents, although still of
some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have
the latest edition of any IEEE Standard.
