20、EMENTS Part 16-16: Mechanical tests on contacts and terminations Test 16p: Torsional strength, fixed male tabs 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing electomechanical components within the scope of IEC technical committee 48. It may

21、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 determine the ability of a fixed male tab and its fixing to withstand a specified torque. If so specified in the detail specification, forces other t

22、han torsional may be applied. 2 Normative references The following referenced documents are indispensable for the application of this document.

It may be wired if so specified in the deta

Three such specimens shall be prepared. 3.2 Equipment A universal testing machine suitable for the test procedure detailed in Clause 4 shall be required, equipped with all relevant test fixtures needed to hold

The torque shall be steadily increased from zero to that specified in the component specification. This torque shall be maintained for 1 minute. The torque shall be removed, and

28、 the (permanent) displacement of the tab shall be measured. Permanent displacement is defined as the difference between the initial position of the tab before application of any torque and its position after all torque is removed. At least 10 tabs shall be selected at random from the 3 specimens pro

29、vided that at least one tab shall be near the periphery, and one, at or near, the centre of the connector insert or BS EN 60512-16-16:2008Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 26/05/2009 07:25, Uncontrolled Copy, (c) BSI 6 60512-16-16 IEC:2008 housing. For inserts or housings having

30、 3 or less tabs, all tabs shall be tested. This shall be repeated, on an adjacent (new) tab, with the torque being applied in the opposite direction. 4.2 Measurements and requirements 4.2.1 Before testing Visual examination according to IEC 60512-1-1 shall be carried out. There shall be no defects w

31、hich would impair the validity of the test. 4.2.2 During testing The displacement and permanent displacement of the component, measured at the plane of application of the torque shall be measured. NOTE In the case of a tab being made from a highly resilient material (e.g. spring steel or beryllium c

32、opper) the displacement may be large whilst the permanent displacement is negligible. In the case of a tab being held in a plastic material, recovery of displacement of that material may take place over a period. Furthermore, as the properties of such plastic materials may vary considerably with tem

33、perature, these tests will normally be done at laboratory temperatures (NTP), and any deviation from this should be given in the relevant detail specification. The permanent displacement shall not exceed any value given in the component detail specification. 4.2.3 After testing Visual examination ac

34、cording to IEC 60512-1-1 shall be carried out. There shall be no defects that would impair the normal functioning of the connector. This shall be judged by a mating test with its counterpart. 5 Details to be specified When this test is required by a detail specification, the following shall be given

35、 therein: a) whether preconditioning is required; b) whether the specimen is to be wired, and if so, details of this; c) whether special mounting of the specimen is required; d) torque to be applied and orientation with respect to the tab; e) allowable permanent set; f) number of specimens to be tes

36、ted shall be 3 unless otherwise specified; g) any deviation from the standard test method. _ BS EN 60512-16-16:2008Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 26/05/2009 07:25, Uncontrolled Copy, (c) BSIThis page deliberately left blankLicensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS
