20、ndardization/InternationalElectrotechnicalCommission Casepostale56 CH-1211Genve20 Switzerland IEEE Standardsdocuments are developed within the IEEE Societies and the Standards Coordinating Com- mittees of the IEEE Standards Association (IEEE-SA) Standards Board. Members of the committees serve volun
21、tarily 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 that have expressed an interest in participating in the
22、 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 viewpo
23、int 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 Standard is subjected to review at least every ve years for revision or reafrmation. When a documen
24、t is more than ve years old and has not been reafrmed, it is rea- sonable to conclude that its contents, although still of some value, do not wholly reect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. Comments for revi
25、sion of IEEE Standards are welcome from any interested party, regardless of membership afliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regard
26、ing the meaning of portions of standards as they relate to specic applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is imp
27、ortant 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 Committees are not able to provide an instant response to interpretation requests except in those cases where the ma
28、tter has previously received formal consideration. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE-SA Standards Board 445 Hoes Lane P.O.
