8、he IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its stan- dards through a consensus development process, approved by the American

9、 National Standards Institute, which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compens

10、ation. While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the informati

11、on contained in its standards.Use of an IEEE Standard is wholly voluntary. The IEEE disclaims liability for any personal injury, prop- erty or other damage, of any nature whatsoever, whether special, indirect, consequent

12、ial, or compensatory, directly or indirectly resulting from the publication, use of, or reliance upon this, or any other IEEE Stan- dard document.The IEEE does not warrant or represent the accuracy or content of the mate

13、rial contained herein, and expressly disclaims any express or implied warranty, including any implied warranty of merchantability or fitness for a specific purpose, or that the use of the material contained herein is fre

14、e from patent infringe- ment. IEEE Standards documents are supplied “AS IS.”The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other good

15、s and services related to the scope of the IEEE Standard. Further- more, 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 a

16、rt and comments received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is more than five years old and has not been reaffi

17、rmed, it is reasonable to conclude that its con- tents, 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

18、 IEEE Standard.In publishing and making this document available, the IEEE is not suggesting or rendering professional or other services for, or on behalf of, any person or entity. Nor is the IEEE undertaking to perform a

19、ny duty owed by any other person or entity to another. Any person utilizing this, and any other IEEE Standards document, should rely upon the advice of a competent professional in determining the exercise of reason- able

20、 care in any given circumstances.Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to t

21、he attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of concerned interests, it is important to ensure that any interpretation has also rec

22、eived 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

23、in those cases where the matter has previously received formal consideration. Comments for revision of IEEE Standards are welcome from any interested party, regardless of member- ship affiliation with IEEE. Suggestions f

24、or changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Comments on standards and requests for interpretations should be addressed to:Secretary, IEEE-SA
