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:
Secretary, IEEE-SA Standards Board
445 Hoes Lane
Piscataway, NJ 08854

Photocopies: Authorization to photocopy portions of any individual standard for internal or personal use is granted by
The Institute of Electrical and Electronics Engineers, Inc., provided that the appropriate fee is paid to Copyright
Clearance Center. To arrange for payment of licensing fee, please contact Copyright Clearance Center, Customer
Service, 222 Rosewood Drive, Danvers, MA 01923 USA; +1 978 750 8400. Permission to photocopy portions of any
individual standard for educational classroom use can also be obtained through the Copyright Clearance Center.

Notice to users
Laws and regulations
Users of IEEE Standards documents should consult all applicable laws and regulations. Compliance with the
provisions of any IEEE standards document does not imply compliance to any applicable regulatory
requirements. Implementers of the standard are responsible for observing or referring to the applicable
regulatory requirements. IEEE does not, by the publication of its standards, intend to urge action that is not
in compliance with applicable laws, and these documents may not be construed as doing so.
Copyrights
This document is copyrighted by the IEEE. It is made available for a wide variety of both public and private
uses. These include both use, by reference, in laws and regulations, and use in private self-regulation,
standardization, and the promotion of engineering practices and methods. By making this document
available for use and adoption by public authorities and private users, the IEEE does not waive any rights in
copyright to this document.
Updating of IEEE documents
Users of IEEE standards should be aware that these documents may be superseded at any time by the
issuance of new editions or may be amended from time to time through the issuance of amendments,
corrigenda, or errata. An official IEEE document at any point in time consists of the current edition of the
document together with any amendments, corrigenda, or errata then in effect. In order to determine whether
a given document is the current edition and whether it has been amended through the issuance of
amendments, corrigenda, or errata, visit the IEEE-SA website or contact the IEEE at the address listed
previously. For more information about the IEEE Standards Association or the IEEE standards development
process, visit the IEEE-SA website.
Errata
Errata, if any, for this and all other standards can be accessed at the following URL: http://
standards.ieee.org/findstds/errata/index.html. Users are encouraged to check this URL for errata
periodically.
Patents
Attention is called to the possibility that implementation of this standard may require use of subject matter
covered by patent rights. By publication of this standard, no position is taken by the IEEE with respect to the
existence or validity of any patent rights in connection therewith. A patent holder or patent applicant has
filed a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE-
SA website http://standards.ieee.org/about/sasb/patcom/patents.html. Letters of Assurance may indicate
whether the Submitter is willing or unwilling to grant licenses under patent rights without compensation or
under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair
discrimination to applicants desiring to obtain such licenses.
Essential Patent Claims may exist for which a Letter of Assurance has not been received. The IEEE is not
responsible for identifying Essential Patent Claims for which a license may be required, for conducting
inquiries into the legal validity or scope of Patents Claims, or determining whether any licensing terms or
conditions provided in connection with submission of a Letter of Assurance, if any, or in any licensing
agreements are reasonable or nondiscriminatory. Users of this standard are expressly advised that
determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their
own responsibility. Further information may be obtained from the IEEE Standards Association.
