The IEEE develops its standardsthrough a consensus
8、 development process, approved by the American National Standards Institute, which bringstogether volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are notnecessarily members of the Institute and serve without compensation. While the IEEE administers th
9、e processand establishes rules to promote fairness in the consensus development process, the IEEE does not independentlyevaluate, 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 person
10、al injury, property orother damage, of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly orindirectly 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 con

IEEE Standardsdocuments are supplied “
12、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 goods and services related to the scope of the IEEE Standard. Furthermore, theviewpoint expressed at the time a standard is approved and issued is subject
13、 to change brought about throughdevelopments in the state of the art and comments received from users of the standard. Every IEEE Standard issubjected to review at least every five years for revision or reaffirmation. When a document is more than fiveyears old and has not been reaffirmed, it is reas
14、onable to conclude that its contents, 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 thelatest edition of any IEEE Standard.In publishing and making this document available, the IEEE is not suggesting or rende

When the need for interpretations is brought to the attention of IEEE, the Institute willinitiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of concernedinterests, it is important to ensure that any interpretation has also r
