12、ndividual presenting information on IEEE standards shallmake it clear that his or her views should be considered the personal views of that individual rather than theformal position of IEEE.Comments on standardsComments for revision of IEEE Standards documents are welcome from any interested party,
13、regardless ofmembership affiliation with IEEE. However, IEEE does not provide consulting information or advicepertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of aproposed change of text, together with appropriate supporting comments. Since IEEE stan
14、dards represent aconsensus of concerned interests, it is important that any responses to comments and questions also receivethe concurrence of a balance of interests. For this reason, IEEE and the members of its societies andStandards Coordinating Committees are not able to provide an instant respon
15、se to comments or questionsexcept in those cases where the matter has previously been addressed. For the same reason, IEEE does notrespond to interpretation requests.

Compliance with theprovisions of any IEEE Standards document d
17、oes not imply compliance to any applicable regulatoryrequirements. Implementers of the standard are responsible for observing or referring to the applicableregulatory requirements. IEEE does not, by the publication of its standards, intend to urge action that is notin compliance with applicable laws
18、 and these documents may not be construed as doing so.CopyrightsIEEE draft and approved standards are copyrighted by IEEE under U.S. and international copyright laws.They are made available by IEEE and are adopted for a wide variety of both public and private uses.

22、EEE Standards documents Users of IEEE Standards documents should be aware that these documents may be superseded at any timeby the issuance of new editions or may be amended from time to time through the issuance of amendments,corrigenda, or errata.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 con
23、sists of the current edition of thedocument together with any amendments, corrigenda, or errata then in effect. Every IEEE standard is subjected to review at least every ten years. When a document is more than ten yearsold and has not undergone a revision process, it is reasonable to conclude that i
24、ts contents, although still ofsome value, do not wholly reflect the present state of the art. Users are cautioned to check to determine thatthey have the latest edition of any IEEE standard.In order to determine whether a given document is the current edition and whether it has been amendedthrough t
25、he issuance of amendments, corrigenda, or errata, visit the IEEE-SA Website at http:/ieeexplore.ieee.org or contact IEEE at the address listed previously.

26、 if any, for all IEEE standards can be accessed on the IEEE-SA Website at the following URL: http:/standards.ieee.org/findstds/errata/index.html. Users are encouraged to check this URL for errataperiodically.PatentsAttention is called to the possibility that implementation of this standard may requ
27、ire use of subject mattercovered by patent rights. By publication of this standard, no position is taken by the IEEE with respect to theexistence or validity of any patent rights in connection therewith. If a patent holder or patent applicant hasfiled a statement of assurance via an Accepted Letter
28、of Assurance, then the statement is listed on the IEEE-SA Website at http:/standards.ieee.org/about/sasb/patcom/patents.html. Letters of Assurance may indicatewhether the Submitter is willing or unwilling to grant licenses under patent rights without compensation orunder reasonable rates, with reaso
29、nable terms and conditions that are demonstrably free of any unfairdiscrimination 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 notresponsible for identifying Essential Patent Claims for which a lic
30、ense may be required, for conductinginquiries into the legal validity or scope of Patents Claims, or determining whether any licensing terms orconditions provided in connection with submission of a Letter of Assurance, if any, or in any licensingagreements are reasonable or non-discriminatory. Users
31、 of this standard are expressly advised thatdetermination of the validity of any patent rights, and the risk of infringement of such rights, is entirely theirown responsibility.
