19、NIC EQUIPMENT TESTS AND MEASUREMENTS Part 16-8: Mechanical tests on connections and terminations Test 16h: Insulating grip effectiveness (crimped connections) FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national elect
20、rotechnical 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 activities, IEC publishes International Standards, Technical Specific
21、ations, 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 dealt with may participate in this preparatory work. Internation
22、al, 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 determined by agreement between the two organizations. 2) The formal de
23、cisions 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 Committees. 3) IEC Publications have the form of recommendations for int
24、ernational 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 they are used or for any misinterpretation by any end user. 4) In
25、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 and the corresponding national or regional publication shall be
26、clearly indicated in the 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
27、shall attach to IEC or 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
28、legal fees) and expenses 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
29、publication. 9) Attention 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 60512-16-8 has been prepared by subcommittee 48B: C
30、onnectors, of IEC technical committee 48: Electromechanical components and mechanical structures for electronic equipment. This standard cancels and replaces test 16h 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 st
31、ructure of the IEC 60512 series. 60512-16-8 IEC:2008 3 The text of this standard is based on the following documents: FDIS Report on voting 48B/1871/FDIS 48B/1903/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. T
32、his publication has been 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 pu
33、blication will remain unchanged 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 60512-16-8 IEC:200
34、8 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 16-8: Mechanical tests on connections and terminations Test 16h: Insulating grip effectiveness (crimped connections) 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing connectors
35、within the scope of technical committee 48. It 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 assess the effectiveness of an insulation grip to hold the insulation of a cable/wire under specif
36、ied conditions. 2 Normative references The following 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-
37、1-1, Connectors for electronic equipment Tests and measurements Part 1-1: General examination Test 1a: Visual examination 3 Preparations 3.1 Preparation of specimen The specimens shall consist of even quantities of cable with the largest insulation specified for the grip, and the smallest. The speci
38、mens shall consist of a crimp contact or terminal end and the specified cable(s); these shall be prepared (crimped) in the manner given in the relevant detail specification or if none are given, the manufacturers instructions. The crimp contact/terminal end shall be crimped in the manner previously
39、stated, but the cable/wire shall be held by the insulation grip only. NOTE Either crimping a separate piece of wire or cutting the conductor after crimping may achieve this. The un-stripped cable/wire shall be at least 100 mm in length. If lubricant is required by the component detail specification,
40、 this shall be applied in the manner so specified. Similarly, if the manufacturers crimping or other assembly devices specify a lubricant, this shall be applied. 3.2 Equipment A mandrel having a diameter equal to that as specified for the flexibility test of the relevant wire/cable shall be provided
41、. 60512-16-8 IEC:2008 5 3.3 Pre-conditioning Any pre-conditioning of the samples required by the applicable detail specification shall be applied. 4 Test method 4.1 Temperature It is recognized that temperature has a significant effect on the flexibility of cable insulation. These tests shall be car
42、ried out under normal laboratory conditions unless otherwise stated in the relevant detail specification. 4.2 Procedure The crimp(ed) contact/terminal shall be held tangential to the mandrel. The wire shall be wound around the mandrel for at least one complete turn and shall be in contact with the m
43、andrel where it enters the insulation grip. Sufficient tension, as specified in the relevant detail specification, shall be applied to the wire to keep it in contact with the mandrel. A test made by first winding the wire in one direction then in the opposite direction shall be considered one cycle.
44、 This cycle shall be done at least ten times. The rotational position of the specimen relative to the direction of bending shall be varied during each cycle such that forces are applied in at least four directions mutually at right angles to each other relative to the grip. NOTE It is recognized tha
45、t grip devices have a best and worst direction of support. The above requirement is intended to test in both the best and worst directions. 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
46、 impair the validity of the test. 4.3.2 During testing None. 4.3.3 After testing The conductor shall be withdrawn from the cable/wire and examined for damage (caused by either the grip crimping process or the testing). This may be done by stripping the insulation from the far end of the cable/wire a
47、nd applying a tensile load between the bared conductor and the crimp terminal. Visual examination according to IEC 60512-1-1 shall be done. There shall be no defects, other than those found under 4.3.1, which would impair the normal functioning of the component. 5 Details to be specified When this t
48、est is required by the detail specification, the following details shall be specified: a) whether preconditioning is required; b) cable/wire/insulation size(s) to be used; c) number of specimens to be tested for each grip size; 6 60512-16-8 IEC:2008 d) details of assembly tooling; e) whether lubrica
49、nt, including that for application tooling, is to be used; f) whether special mounting of the specimen is required; g) tension to be applied; h) number of cycles (if other than 10); i) any deviation in from the standard test method. _ 8 60512-16-8 CEI:2008 COMMISSION LECTROTECHNIQUE INTERNATIONALE _ CONNECTEURS POUR QUIPEMENTS LECTRONIQUES ESSAIS ET MESURES Parti
