These noticesand discl
8、aimers, or a reference to this page, appear in all standards and may be found under the heading“Important Notice” or “Important Notices and Disclaimers Concerning IEEE Standards Documents.”Notice and Disclaimer of Liability Concerning the Use of IEEE StandardsDocumentsIEEE Standards documents (stand
9、ards, recommended practices, and guides), both full-use and trial-use, aredeveloped within IEEE Societies and the Standards Coordinating Committees of the IEEE StandardsAssociation (“IEEE-SA”) Standards Board. IEEE (“the Institute”) develops its standards through aconsensus development process, appr
10、oved by the American National Standards Institute (“ANSI”), whichbrings together volunteers representing varied viewpoints and interests to achieve the final product.Volunteers are not necessarily members of the Institute and participate without compensation from IEEE.While IEEE administers the proc
11、ess and establishes rules to promote fairness in the consensus developmentprocess, IEEE does not independently evaluate, test, or verify the accuracy of any of the information or thesoundness of any judgments contained in its standards.IEEE does not warrant or represent the accuracy or content of th
12、e material contained in its standards, andexpressly disclaims all warranties (express, implied and statutory) not included in this or any otherdocument relating to the standard, including, but not limited to, the warranties of: merchantability; fitnessfor a particular purpose; non-infringement; and
13、quality, accuracy, effectiveness, currency, or completeness ofmaterial. In addition, IEEE disclaims any and all conditions relating to: results; and workmanlike effort.IEEE standards documents are supplied “AS IS” and “WITH ALL FAULTS.”Use of an IEEE standard is wholly voluntary. The existence of an
14、 IEEE standard does not imply that thereare no other ways to produce, test, measure, purchase, market, or provide other goods and services related tothe scope of the IEEE standard. Furthermore, the viewpoint expressed at the time a standard is approved andissued is subject to change brought about th
15、rough developments in the state of the art and commentsreceived from users of the standard. In publishing and making its standards available, IEEE is not suggesting or rendering professional or otherservices for, or on behalf of, any person or entity nor is IEEE undertaking to perform any duty owed
16、by anyother person or entity to another. Any person utilizing any IEEE Standards document, should rely upon hisor her own independent judgment in the exercise of reasonable care in any given circumstances or, asappropriate, seek the advice of a competent professional in determining the appropriatene
17、ss of a given IEEEstandard.IN NO EVENT SHALL IEEE BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO:PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS; ORBUSINESS INTERRUPTION) HOWEVER CAUSED AND ON ANY
18、THEORY OF LIABILITY,WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OROTHERWISE) ARISING IN ANY WAY OUT OF THE PUBLICATION, USE OF, OR RELIANCE UPONANY STANDARD, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE ANDREGARDLESS OF WHETHER SUCH DAMAGE WAS FORESEEABLE.Copyright 2014
19、 IEEE. All rights reserved. iiiTranslations The IEEE consensus development process involves the review of documents in English only. In the eventthat an IEEE standard is translated, only the English version published by IEEE should be considered theapproved IEEE standard.Official statements A statem
20、ent, written or oral, that is not processed in accordance with the IEEE-SA Standards BoardOperations Manual shall not be considered or inferred to be the official position of IEEE or any of itscommittees and shall not be considered to be, or be relied upon as, a formal position of IEEE. At lectures,
21、symposia, seminars, or educational courses, an individual 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
22、documents are welcome from any interested party, 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
23、 appropriate supporting comments. Since IEEE standards 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 Com
24、mittees are not able to provide an instant response to comments or questionsexcept in those cases where the matter has previously been addressed. For the same reason, IEEE does notrespond to interpretation requests. Any person who would like to participate in revisions to an IEEEstandard is welcome
25、to join the relevant IEEE working group.Comments on standards should be submitted to the following address:Secretary, IEEE-SA Standards Board 445 Hoes Lane Piscataway, NJ 08854 USALaws and regulations Users of IEEE Standards documents should consult all applicable laws and regulations. Compliance wi
26、th theprovisions of any IEEE Standards document does 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 act

32、 An official IEEE document at any point in time consists 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 re
33、vision process, it is reasonable to conclude that its 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 curre
34、nt edition and whether it has been amendedthrough the issuance of amendments, corrigenda, or errata, visit the IEEE-SA Website at http:/ieeexplore.ieee.org/xpl/standards.jsp or contact IEEE at the address listed previously.

Users are encouraged to check this URL for errataperiodically.PatentsAttention is ca
36、lled to the possibility that implementation of this standard may require 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 paten
37、t applicant hasfiled a statement of assurance via an Accepted Letter 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 pa
38、tent rights without compensation orunder reasonable rates, with reasonable 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 n
39、otresponsible for identifying Essential Patent Claims for which a license 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 i
40、n any licensingagreements are reasonable or non-discriminatory. Users 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.
