The standardsdeveloped within IEEE represent a consensus of the broad expertise on the subject within the Institute aswell as those activities outside of I
6、EEE that have expressed an interest in participating in the development ofthe standard.Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that thereare no other ways to produce, test, measure, purchase, market, or provide other goods and services related to
7、the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved andissued is subject to change brought about through developments in the state of the art and commentsreceived from users of the standard. Every IEEE Standard is subjected to review at least every
8、 five years forrevision or reaffirmation. When a document is more than five years old and has not been reaffirmed, it is rea-sonable to conclude that its contents, although still of some value, do not wholly reflect the present state ofthe art.

When the need for interpretations is brought to the attention of IEEE, theInstitute will initiate action to prepare appropriate responses. Since IEEE Standards r
