21、9-3 IEC:2011 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 9-3: Endurance tests Test 9c: Mechanical operation (engaging and separating) with electrical load FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide

22、 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 standardization in the electrical and electronic fields. To this end and in addition to other activi

23、ties, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject d

24、ealt 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 with the International Organization for Standardization (ISO) in accordance with conditions determi

25、ned 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 subjects since each technical committee has representation from all interested IEC National Committe

26、es. 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 technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which th

27、ey 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 possible in their national and regional publications. Any divergence between any IEC Publication

28、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 conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not res

29、ponsible 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 directors, employees, servants or agents including individual experts and members of its technical c

30、ommittees 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 arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Public

31、ations. 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 drawn to the possibility that some of the elements of this IEC Publication may be the subject of p

32、atent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60512-9-3 has been prepared by subcommittee 48B: Connectors, of IEC technical committee 48: Electromechanical components and mechanical structures for electronic equipment. This

33、second edition cancels and replaces the first edition, published in 2006, and constitutes a technical revision. The main technical changes with regard to the previous edition are as follows: An additional requirement to 4.1 stating that if more than one electrical circuit is wired for testing, the w

34、iring shall be carried out in a parallel electrical circuit. Subclauses 4.3 through 4.7 were removed and replaced by 4.2 through 4.4. 4 60512-9-3 IEC:2011 This standard is to be read in conjunction with IEC 60512-1 and IEC 60512-1-100, which explains the structure of the IEC 60512 series. The text o

35、f this standard is based on the following documents: FDIS Report on voting 48B/2238/FDIS 48B/2244/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC D

36、irectives, Part 2. A list of all parts in the IEC 60512 series, under the general title Connectors for electronic equipment Tests and measurements, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicate

37、d on the IEC web site under “http:/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. 60512-9-3 IEC:2011 5 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 9-3: Endu

38、rance tests Test 9c: Mechanical operation (engaging and separating) with electrical load 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing connectors within the scope of IEC technical committee 48. This test may also be used for similar devices

39、 when specified in a detail specification. The object of this standard is to define a standard test method to assess the mechanical and electrical operational endurance, i.e. engaging and separating cycles, of a connector in an operating mode which includes a specified electrical load. 2 Normative r
