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 implemented at national level

16、equired 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 effectiveness of the insert

17、retaining system to withstand axial loads likely to be encountered during normal use. NOTE The test method detailed in this document is a companion to the one detailed in IEC 60512-15-3 (see bibliographic reference). 2 Normative references The following referenced documents are indispensable for the

18、 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 and measurements Part 1-1: General examination Test

19、1a: Visual examination 3 Preparations 3.1 Preparation of specimen The specimen shall consist of a connector with its terminations, and may be wired if so specified in the detail specification. Cable fittings and accessories shall not be fitted. Any preconditioning given in the detail specification s

20、hall be applied. 3.2 Equipment For the application of the axial loads, a suitable device able to provide the controls on the loads (intensity, rate of increase, time of constant load application) shall be required (e.g.: a universal materials testing machine). In the case of the axial loads being ap

21、plied by air or gas pressure, a chamber to contain connectors that may be ejected in case of retention failure shall be provided. If hydraulic pressure is used, such a chamber may not be necessary. However compatibility between materials contained within the specimen and such fluids must be ensured.

22、 NOTE 1 Where air pressure is used, there is a possibility that contacts, inserts or other objects being ejected at high velocity. NOTE 2 If the detail specification requires special preconditioning of the specimen, all the necessary equipment detailed in the relevant documents describing such condi

23、tioning would also be required. BS EN 60512-15-2:2008 3 3.3 Mounting Mounting of the specimen shall be as specified in the detail specification. 4 Test method 4.1 Procedure Unless otherwise stated in the detail specification, 3 connectors shall be tested. 4.1.1 Force method The housing of the connec

24、tor shall be fixed in such a manner as not to influence the insert retention means. A specified axial force shall be applied in both directions consecutively, at a constant rate of 25 mm/min, until the specified force is achieved. This shall then be maintained for 1 minute. 4.1.2 Pressure method The

25、 displacement caused by the specified force or pressure if any shall be measured. Any residual displacement after the specified force or pressure is removed if any shall be measured. These displacements shall be recorded. The axial displacement of the insert shall not exceed that which may be given

26、in the detail specification. 4.2 Measurements 4.2.1 Before testing Visual examination according to IEC 60512-1-1 shall be done. 4.2.2 During testing There shall be no displacement of the insert during or after the test that would impair the normal operation of the connector. 4.2.3 After testing Visu

27、al examination 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) wiring of the specimen; d) mounting of t

28、he specimen; e) axial load or pressure to be applied; f) permitted displacement, if any (during and after the test); g) any deviation from the standard test method.
