6、 documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which brings toget

While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, th
8、e IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its standards. Use of an IEEE Standard is wholly voluntary. The IEEE disclaims liability for any personal injury, property or other damage, of any nature whatsoever, whether special, indirect,
9、 consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance upon this, or any other IEEE Standard document. The IEEE does not warrant or represent the accuracy or content of the material contained herein, and expressly disclaims any express or implied
10、warranty, including any implied warranty of merchantability or fi tness for a specifi c purpose, or that the use of the material contained herein is free from patent infringement. IEEE Standards documents are supplied AS IS. The existence of an IEEE Standard does not imply that there are no other wa
11、ys to produce, test, measure, purchase, market, or provide 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 commen
12、ts received from users of the standard. Every IEEE Standard is subjected 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 no

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

Any person utilizing this, and any other IEEE Standards document, should rely upon the advice of a competent professional in determining the exercise of reasonable care in any given circumstance
15、s. 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 to prepare appropriate responses. Since IEEE Standar
16、ds represent a consensus of 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 Committees are not able to provide an instant response to
17、interpretation requests except 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 membership affi liation with IEEE. Suggestions for changes in documents should be in the form of a
18、 proposed change of text, together with appropriate supporting comments. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE-SA Standards Board 445 Hoes Lane P.O.
