Foreword The text of document 48B/1845/FDIS, future edition 1 of IEC 60512-15-3, prepared by SC 48B, Connectors, of IEC TC 48, Electromechanical components and mechanical structures for electronic equipment, was submitted t
13、o the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60512-15-3 on 2008-07-01. This standard is to be read in conjunction with EN 60512-1 and EN 60512-1-100 which explains the structure of the EN 60512 series. The following dates were fixed: latest date by which the EN has to be impleme
14、nted at national level by publication of an identical national standard or by endorsement (dop) 2009-04-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-07-01 Annex ZA has been added by CENELEC. _ Endorsement notice The text of the International
15、Standard IEC 60512-15-3:2008 was approved by CENELEC as a European Standard without any modification. _ BS EN 60512-15-3:2008 2 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 15-3: Connector tests (mechanical) Test 15c: Insert retention in housing (torsional) 1 Scope and object This
16、 part of IEC 60512, when required by the detail specification, is used for testing connectors 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 document is to detail a standard test method to assess the ef
17、fectiveness of the insert retaining system to withstand torsional stresses likely to be encountered during normal use. NOTE The test method detailed in this document is a companion to the one detailed in IEC 60512-15-2 (see bibliographic reference). 2 Normative references The following referenced do
18、cuments are indispensable for the application of this document. For dated references, only the edition cited applies.

19、rt 1-1: General examination Test 1a: Visual examination 3 Preparations 3.1 Preparation of specimen The specimen shall consist of a connector with its terminations, and wired if so specified in the detail specification. Cable fittings and accessories shall not be fitted. Any preconditioning given in
20、the detail specification shall be applied. 3.2 Equipment For the application of the torsional loads, a suitable device able to provide the controls on the torque (intensity, rate of increase, time of constant torque application) shall be required (e.g.: a torsion testing machine). NOTE If the detail
21、 specification requires special preconditioning of the specimen, all the necessary equipment detailed in the relevant documents describing such conditioning would also be required 3.3 Mounting Mounting of the specimen shall be as specified in the detail specification. BS EN 60512-15-3:2008 3 4 Test
22、method Unless otherwise stated in the detail specification, 3 connectors shall be tested. 4.1 Procedure The housing of the connector shall be fixed in such a manner as not to influence the insert retention means. A specified torque shall be applied utilising the test fixture specified in the detail
23、specification. The torque shall be applied at a rate of 0,5 Nm/s until the specified torque is achieved and held at that value for 1 min. 4.2 Measurements 4.2.1 Before testing Visual examination according to IEC 60512-1-1 shall be done. 4.2.2 During testing The displacement caused by the specified t
24、orque shall be measured. Any residual displacement after the specified torque is removed shall be measured. These displacements shall be recorded. The angular displacement of the insert if any shall not exceed that which may be given in the detail specification. 4.2.3 After testing Visual examinatio
25、n according to IEC 60512-1-1 shall be done. 5 Details to be specified When this test is required by a detail specification, the following shall be given therein: a) the number of connectors to test if other than 3; b) preconditioning required; c) fitment of contacts and wiring of the specimen; d) mo
26、unting of the specimen; e) test fixture to be used; f) torque to be applied; g) permitted displacement, if any (during and after the test); h) any deviation from the standard test method.
