19、PMENT TESTS AND MEASUREMENTS Part 16-9: Mechanical tests on contacts and terminations Test 16i: Grounding contact spring holding force FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (
20、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 activities, IEC publishes International Standards, Technical Specifications, Technical Report
21、s, 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 dealt with may participate in this preparatory work. International, governmental and non
22、- 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 determined by agreement between the two organizations. 2) The formal decisions or agreements o
23、f 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 Committees. 3) IEC Publications have the form of recommendations for international use and are
24、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 they are used or for any misinterpretation by any end user. 4) In order to promote intern
25、ational 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 and the corresponding national or regional publication shall be clearly indicated in th
26、e latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or
27、its directors, 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 expense
28、s arising 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) Attenti
29、on is 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 60512-16-9 has been prepared by subcommittee 48B: Connectors, of IEC techn
30、ical committee 48: Electromechanical components and mechanical structures for electronic equipment. This standard cancels and replaces test 16i of IEC 60512-8, issued in 1993. This standard is to be read in conjunction with IEC 60512-1 and IEC 60512-1-100 which explains the structure of the IEC 6051
31、2 series. 60512-16-9 IEC:2008 3 The text of this standard is based on the following documents: FDIS Report on voting 48B/1872/FDIS 48B/1904/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 bee
32、n drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of 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 u
33、nchanged until the maintenance result date indicated 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. 4 60512-16-9 IEC:2008 CONNECTORS FOR ELECTR
34、ONIC EQUIPMENT TESTS AND MEASUREMENTS Part 16-9: Mechanical tests on contacts and terminations Test 16i: Grounding contact spring holding force 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing electomechanical components within the scope of te
35、chnical committee 48. This test may also be used for similar devices when specified in a detail specification. The object of this part of IEC 60512 is to detail a standard test method to determine the holding capacity of grounding contact springs by means of gauges. 2 Normative references The follow
36、ing referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60512-1-1, Connectors for electronic equipment Tests an
37、d measurements Part 1-1: General examination Test 1a: Visual examination ISO 1302, Geometrical Product Specification (GPS) Indication of surface texture in technical product documentation 3 Preparations 3.1 Preparation of specimen The specimen shall consist of a component with its terminations, and
38、may be wired if so specified in the component detail specification. If lubricant is specified for use with the contact system, it shall be applied in the manner specified in the component detail specification. Any preconditioning given in the component detail specification shall be applied. 3.2 Equi
39、pment Set(s) of gauges as specified in the component detail specification, shall be provided. 3.3 Mounting If mounting of the specimen is appropriate, it shall be as specified in the component detail specification. 60512-16-9 IEC:2008 5 4 Test methods 4.1 Method A Single contact gauges 4.1.1 Female
40、contact springs Each contact to be tested shall have the maximum size gauge specified, engaged and separated three times. After which, the minimum size retention force gauge specified shall be inserted. 4.1.2 Male contact springs Each contact to be tested shall have the minimum size gauge specified,
41、 engaged and separated three times. After which, the contact shall be inserted into the maximum size retention force gauge specified. 4.2 Method B Multiple contact gauges As Method A, except that contacts shall be tested in specified groups using gauges having multiple contact engaging elements. Aft
42、er which appropriate individual maximum or minimum gauges shall be used. 4.3 Measurements and requirements 4.3.1 Before testing Visual examination according to IEC 60512-1-1 shall be carried out. There shall be no defects, which would impair the validity of the test. 4.3.2 During testing Contacts sh
43、all support the weight of the individual contact retention force gauge in a vertically downward direction. 4.3.3 After testing Visual examination according to IEC 60512-1-1 shall be carried out. There shall be no defects that would impair the normal functioning of the component. Special attention sh
44、all be given to the resilient features of the specimen. 5 Details to be specified When this test is required by a detail specification, the following details shall be specified: a) whether preconditioning is required; b) nature and means of application of any lubricant to be applied; c) whether the
45、specimen is to be wired, and if so, details of this; d) whether special mounting of the specimen is required; e) details of gauges to be used, including surface roughness, according to ISO 1302; f) number of specimens to be tested; g) any deviation from the standard test method. _ 6 60512-16-9 CEI:2
