Comments on standardsComments for revision of IEEE Standards documents are welcome from any interested party, regardless ofmembership affiliation with IEEE. However, IEEE does not provide co
14、nsulting 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 standards represent aconsensus of concerned interests, it is important that any resp
15、onses 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 response to comments or questionsexcept in those cases where the matter has previously
16、 been addressed. For the same reason, IEEE does notrespond to interpretation requests.

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
24、 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 its contents, although still ofsome value, do not wholly reflect the present state of the art. Users are cautioned to check
25、 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 the issuance of amendments, corrigenda, or errata, visit the IEEE-SA Website at http:/ieeexplore.ieee.org/xpl/standards.jsp

By publication of this standard, no position is taken
28、 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 of Assurance, then the statement is listed on the IEEE-SA Website at http:/standards.ieee.org/about/sasb

Letters of Assurance may indicatewhether the Submitter is willing or unwilling to grant licenses under patent rights without compensation orunder reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfairdiscrimination to applicants desiring
30、 to obtain such licenses.Essential Patent Claims may exist for which a Letter of Assurance has not been received.
