6、ordinat- ing Committees of the IEEE Standards Board. Members of the committees 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 a
7、s those activities outside of IEEE that have expressed an interest in participating in the develop- ment 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
8、 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 and comments received from users of the standard. Every IEEE Standar
9、d is sub- jected to review at least every fi ve years for revision or reaffi rmation. When a document is more than fi ve years old and has not been reaffi rmed, it is reasonable to conclude that its contents, although still of some value, do not wholly refl ect the present state of the art. Users ar
10、e cautioned 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 membership affi liation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of
11、 text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specifi c applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action t
12、o prepare appropriate responses. Since IEEE Standards rep- resent a consensus of all concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating C
13、ommittees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE Standards Board 445 Hoes Lane P.O. Box
