5、of the IEEE Standards Association (IEEE-SA) Standards Board. Members of the committees servevoluntarily and without compensation. They are not necessarily members of the Institute. The standardsdeveloped within IEEE represent a consensus of the broad expertise on the subject within the Institute asw
6、ell as those activities outside of IEEE 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
7、 other goods and services related tothe 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 i
8、s subjected to review at least every 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. Users are cautioned
9、 to check to determine that they have the latest edition of any IEEE Standard.Comments for revision of IEEE Standards are welcome from any interested party, regardless of membershipaffiliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change oftext, together
10、 with appropriate supporting comments.Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as theyrelate to specific applications. When the need for interpretations is brought to the attention of IEEE, theInstitute will initiate action to prepare appropria

For this reason, IEEE and the members of its societies and Standards CoordinatingCommittees are not able t
