Foreword The text of document 48B/1849/FDIS, future edition 1 of IEC 60512-15-7, prepared by SC 48B, Connectors, of IEC TC 48, Electromechanical components and mechanical structures for electronic equipment, was submitt

13、ed to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60512-15-7 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 imp

14、lemented 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or by endorsement (dop) 2009-04-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-07-01 Annex ZA has been added by CENELEC.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 Internatio

15、nal Standard IEC 60512-15-7:2008 was approved by CENELEC as a European Standard without any modification. _ BS EN 60512-15-7:2008 2 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 15-7: Connector tests (mechanical) Test 15g: Robustness of protective cover attachment 1 Scope and objec

16、t This 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

17、the ability of a connector cover and its attachment to withstand mechanical stresses. NOTE Such a cover may be protective in any sense. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited appli

18、es. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60512-1-1, Connectors for electronic equipment Tests and measurements Part 1-1: General examination Test 1a: Visual examination 3 Preparations 3.1 Preparation of specimen The specimen sh

19、all consist of a cover fixed to its connector or a specified test fixture. Any preconditioning given in the detail specification shall be applied. 3.2 Equipment For the application of the loads, a suitable device able to provide the controls on the loads (intensity, rate of increase, time of constan

20、t load application) shall be required (e.g.: a universal materials testing machine). NOTE If the detail 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 If

21、mounting of the specimen is appropriate, it shall be as specified in the detail specification. 4 Test method Unless otherwise stated in the detail specification, 3 connectors shall be tested. BS EN 60512-15-7:2008 3 4.1 Procedure The specified force shall be applied in the direction of the normal re

22、moval direction of the cover. In the case of screwed caps, this shall not include an unscrewing torque. The specified force shall then be applied perpendicular to the normal removal axis of the cover. This shall be done in four directions in the same plane, mutually at right angles to each other. In

23、 the case of screwed caps only, one such force shall be applied. In some designs there may be a disadvantageous or worst case direction for the application of this force. If so at least one of the four directions shall be in this direction. The load shall be applied at a rate of 25 mm/min. The maxim

24、um load shall be applied for 5 minutes. The force shall then be removed. 4.2 Measurements 4.2.1 Before testing Visual examination according to IEC 60512-1-1 shall be done. 4.2.2 During testing No malfunction of the cover or its attachment system shall occur. 4.2.3 After testing Visual examination ac

25、cording to IEC 60512-1-1 shall be done. Special attention shall be given to the operation of sealing, coupling and retaining devices. 5 Details to be specified When this test is required by a detail specification the following shall be given therein, a) number of connectors to be tested (if other th

26、an 3); b) preconditioning required; c) loads to be applied, point of application may be specified; d) details of test fixture, if corresponding connector is not to be used; e) if any displacement is permitted; f) any deviation from the standard test method. _ BS EN 60512-15-7:2008 4 Annex ZA (normat
