26、conformance testing FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning st
27、andardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their prepar
28、ation is entrusted to technical committees; any IEC National Committee interested in 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 closely w
29、ith the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant su
30、bjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technic
31、al content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent
32、 possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide co
33、nformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services 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 di
34、rectors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses aris
35、ing out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is
36、drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62637-2 has been prepared by technical area 1: Terminals for audio, video and da
37、ta services and content, of IEC technical committee 100: Audio, video and multimedia systems and equipment. This bilingual version (2011-07) replaces the English version. The text of this standard is based on the following documents: CDV Report on voting 100/1674/CDV 100/1750/RVC Full information on
38、 the voting for the approval of this standard can be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon. 62637-2 IEC:2011 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of
39、 the IEC 62637 series, under the general title Battery charging interface for small handheld multimedia devices, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/
40、webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 62637-2 IEC:2011 BATTERY CHARGING INTERFACE FOR SMALL HANDHELD MULTIMEDIA DEVICES Part 2: 2 mm barrel type interface conformanc

46、onditions are set out below. Manufacturers should note that the actual conditions of use could be more stringent. Tests conducted using this conformance document do not replace EMC, ESD, safety, type approval, or any tests set by legislation in the chargers or devices using the charging interface sp
47、ecified in IEC 62637-1. The purpose of the conformance testing is to achieve good interoperability between different chargers and devices. 4.2 Temperature All measurements shall be made at normal room temperature 18 C to 25 C, unless some other temperature is specified. 4.3 Voltage All tests are per
48、formed under nominal operating voltage as defined by the manufacturer. 5 Electrical testing of 2 mm barrel type chargers 5.1 Maximum transient voltage and current values 5.1.1 Test purpose The purpose of this test is to verify that the charger complies with the requirements of settling time, minimum
49、 voltage and maximum voltage limits specified in IEC 62637-1, 5.2. 5.1.2 Requirements The following requirements apply. Maximum charger output overshoot shall be less than or equal to 16 V. Maximum reverse voltage at charger output shall be less than or equal to 1 V.
