Notice and Disclaimer of Liability Concerning the Use of IEEE Documents: IEEE Standards documents are
developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association
(IEEE-SA) Standards Board. IEEE develops its standards through a consensus development process, approved by the
American 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 compensation.
While IEEE administers the process and establishes rules to promote fairness in the consensus development process,
IEEE does not independently evaluate, test, or verify the accuracy of any of the information or the soundness of any
judgments contained in its standards.
Use of an IEEE Standard is wholly voluntary. IEEE disclaims liability for any personal injury, property or other damage,
of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectly resulting from
the publication, use of, or reliance upon any IEEE Standard document.
IEEE does not warrant or represent the accuracy or content of the material contained in its standards, 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 in its standards 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 ways 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 comments received from users of the standard. Every IEEE standard is subjected to review at least
every ten years. When a document is more than ten years old and has not undergone a revision process, it is reasonable
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 the latest edition of any IEEE standard.
In publishing and making its standards available, IEEE is not suggesting or rendering professional or other services for,
or on behalf of, any person or entity. Nor is IEEE undertaking to perform any duty owed by any other person or entity to
another. Any person utilizing any IEEE Standards document, should rely upon his or her own independent judgment in
the exercise of reasonable care in any given circumstances or, as appropriate, seek the advice of a competent professional
in determining the appropriateness of a given IEEE standard.
Translations: The IEEE consensus development process involves the review of documents in English only. In the event
that an IEEE standard is translated, only the English version published by IEEE should be considered the approved IEEE
standard.
Official Statements: A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards
Board Operations Manual shall not be considered the official position of IEEE or any of its committees and shall not be
considered to be, nor be relied upon as, a formal position of IEEE. At lectures, symposia, seminars, or educational
courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be
considered the personal views of that individual rather than the formal position of IEEE.
Comments on Standards: Comments for revision of IEEE Standards documents are welcome from any interested party,
regardless of membership affiliation with IEEE. However, IEEE does not provide consulting information or advice
pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a proposed
change of text, together with appropriate supporting comments. Since IEEE standards represent a consensus of
concerned interests, it is important to ensure that any responses to comments and questions also receive 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 comments or questions except in those cases where the matter has
previously been addressed. Any person who would like to participate in evaluating comments or revisions to an IEEE
standard is welcome to join the relevant IEEE working group at http://standards.ieee.org/develop/wg/
.
Comments on standards should be submitted to the following address:
