17、 (IEC) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in additi
18、on to other activities, IEC publishes International Standards, Technical Specifications,Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IECPublication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interestedi
19、n the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closelywith the International Organization for Standardization (ISO) in accordance with condi
20、tions determined byagreement between the two organizations.2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an internationalconsensus of opinion on the relevant subjects since each technical committee has representation from allinterested IEC National
21、 Committees.3) IEC Publications have the form of recommendations for international use and are accepted by IEC NationalCommittees in that sense. While all reasonable efforts are made to ensure that the technical content of IECPublications is accurate, IEC cannot be held responsible for the way in wh
22、ich they are used or for anymisinterpretation by any end user.4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publicationstransparently to the maximum extent possible in their national and regional publications. Any divergencebetween any IEC Publicatio
23、n and the corresponding national or regional publication shall be clearly indicated inthe latter.5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformityassessment services and, in some areas, access to IEC marks of conformity. IEC is not resp
24、onsible for anyservices carried out by independent certification bodies.6) All users should ensure that they have the latest edition of this publication.7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts andmembers of its technical commit
25、tees and IEC National Committees for any personal injury, property damage orother damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) andexpenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IECPublications.8

BS EN 62680-1-1:2015 4 IEC 62680-1-1:2015 IEC 2015 USB-IF 2014 INTRODUCTION The IEC 62680 series is based on a series of specifications that were ori
33、ginally developed by the USB Implementers Forum (USB-IF). These specifications were submitted to the IEC under the auspices of a special agreement between the IEC and the USB-IF. The USB Implementers Forum, Inc.(USB-IF) is a non-profit corporation founded by the group of companies that developed the
34、 Universal Serial Bus specification. The USB-IF was formed to provide a support organization and forum for the advancement and adoption of Universal Serial Bus technology. The Forum facilitates the development of high-quality compatible USB peripherals (devices), and promotes the benefits of USB and
35、 the quality of products that have passed compliance testing. ANY USB SPECIFICATIONS ARE PROVIDED TO YOU “AS IS, “WITH NO WARRANTIES WHATSOEVER, INCLUDING ANY WARRANTY OF MERCHANTABILITY, NON-INFRINGEMENT, OR FITNESS FOR ANY PARTICULAR PURPOSE.
