Foreword The text of document 48B/1843/FDIS, future edition 1 of IEC 60512-15-1, prepared by SC 48B, Connectors, of IEC TC 48, Electromechanical components and mechanical structures for electronic equipment, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60512-
13、15-1 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 implemented at national level by publication of an identical national standard
14、or by endorsement (dop) 2009-04-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-07-01 Annex ZA has been added by CENELEC.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 Standard IEC 60512-15-1:2008 was approved by CENELEC as a European Stand

16、onnectors within the scope of technical committee 48. This test 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 contact retaining system to withstand axial loads likely t
17、o be encountered during normal use. The contact retaining system may retain the contact in an insert or directly into a housing. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For
18、 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 shall con
19、sist of a connector with its terminations, wired as specified in the detail specification. Any accessory, which do not form part of the contact retention system, shall be removed. Any preconditioning given in the detail specification shall be applied. 3.2 Equipment For the application of the axial l
20、oads, 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). NOTE If the detail specification requires special preconditioning of the specimen, all the necessary equ
21、ipment detailed in the relevant documents describing such conditioning would also be required 3.3 Mounting If mounting of the specimen is appropriate, it shall be as specified in the detail specification. 4 Test method 4.1 Procedure Unless otherwise stated in the detail specification, 3 connectors s
22、hall be tested. BS EN 60512-15-1:2008 3 Unless otherwise specified in the detail specification, for test specimens having fewer than 6 positions, all contacts shall be tested. For test specimens with more than 6 positions, 20 % of contact positions, but not less than 6 nor more than 10, shall be tes
23、ted in each test specimen. For test specimens with more than 6 positions, the contacts tested shall be chosen at random but shall include at least one contact near the periphery and and least one near the centre of the insert or housing. A force shall be applied by movement of the mechanical device
24、used to apply load at a constant rate not exceeding 25 mm/min, until the specified force is applied. This shall then be maintained for 10 s and then removed. The foregoing procedure shall be applied to the selected contacts in turn. 4.2 Measurements 4.2.1 Before testing Visual examination according
25、to IEC 60512-1-1 shall be done. 4.2.2 During testing After the contact is seated on the contact retention device, displacement caused by the specified force shall be measured. Any residual displacement after the specified force is removed shall be measured. These displacements shall be recorded. The
26、 maximum axial displacement for each contact shall be measured and recorded while under load. 4.2.3 After testing Visual examination according to IEC 60512-1-1 shall be done. The maximum axial displacement for each contact after the load is applied shall be measured and recorded. 5 Details to be spe
27、cified When this test is required by a detail specification, the following shall be given therein: a) number of connectors to be tested (if other than 3); b) preconditioning required; c) wiring of the specimen; d) axial load to be applied; e) permitted displacement, if any (during and after the test
28、); f) any deviation from the standard test method. _ BS EN 60512-15-1:2008 4 Annex ZA(normative) Normative references to international publications with their corresponding European publications The following referenced documents are indispensable for the application of this document. For dated refe
29、rences, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
