The ieee develops its standards through a consensusdevelopment process, approved by the American National Standards Institute, which brings together volunteersrepresenting varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of theInstitute and serve without compensation. While the ieee administers the process and establishes rules to promotefairness in the consensus development process, the ieee does not independently evalof any of the information or the soundness of any judgments contained in its standar uate, test, or verify the accuracyUse of an IEEE Standard is wholly voluntary. The ieee disclaims liability for any personal injury, property or otherdamage, of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectlyresulting from the publication, use of, or reliance upon this, or any other iEFF Standard documentThe ieee does not warrant or represent the accuracy or content of the material contained herein, and expresslydisclaims any express or implied warranty, including any implied warranty of merchantability or fitness for a specificpurpose, or that the use of the material contained herein is free from patent infringement.

Furthermore, the vintexpressed at the time a standard is approved and issued is subject to change brought about through developments in thetate of the art and comments received from users of the standard. Every ieee standard is subjected to review at leastevery five years for revision or reaffirmation, or every ten years for stabilization. When a document is more than fiverears old and has not been reaffirmed, or more than ten years old and has not been stabilized, it is reasonable toconclude that its contents, although still of some value, do not wholly reflect the present state of the art.

Any person utilizing this, and any other IEEE Standards document, should rely upon his orher independent judgment in the exercise of reasonable care in any given circumstances or, as appropriate, seek theadvice of a competent professional in deternining the appropriateness of a given IEEE standardInterpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate tospecific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiateaction to prepare appropriate responses. Since IEFF Standards represent a consensus of concerned interests, itimportant 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 instantresponse to interpretation requests except in those cases where the matter has previously received formal considerationA statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board Operations Manualshall not be considered the official position of ieee or any of its committees and shall not be considered to be, nor berelied upon as, a formal interprctation of the IEEE. At lectures, symposia, seminars, or educational courses, anindividual presenting information on IEEE standards shall make it clear that his or her views should be considered thepersonal views of that individual rather than the formal position, explanation, or interpretation of the IeEeComments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliationwith IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together withappropriate supporting comments.
