It ma

20、y 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 specified tensile and compressive forces. If so specified in the detail speci

21、fication, forces other than tension and compression may be applied. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced doc

22、ument (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 specimens shall consist of a connector fitted with one or more male tabs. They

23、may be wired if so specified in the detail specification. Any preconditioning given in the detail specification shall be applied. Three such specimens shall be provided. 3.2 Equipment For the application of the axial loads, a suitable device able to provide the controls on the loads (intensity, rate

24、 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 equipment detailed in the relevant documents describing such conditioning would also

25、be required. An illustration of the application of force is given in Figure 1. 3.3 Mounting If mounting of the specimen is appropriate, it shall be as specified in the component detail specification.

For inserts or housings having 3 or less tabs, all tabs sha

28、ll be tested. This shall be repeated, on an adjacent (new) tab, with the force being applied in the opposite direction (i.e. if tensile is first applied then compression is the next test). A tensile or compressive force F shall be applied to the fixed tab. The tensile or compressive force shall be s

29、teadily increased from zero to that specified in the component specification. This tensile or compressive force shall be maintained for 1 minute. The tensile or compressive force shall then be removed, and the (permanent) displacement of the tab shall be measured after the removal of the tensile or

30、compressive force. Permanent displacement is defined as the difference between the initial position of the tab before application of any tensile or compressive forces and its position after all tensile and compressive force is removed. 4.2 Measurements and requirements 4.2.1 Before testing Visual ex

31、amination according to IEC 60512-1-1 shall be carried out. There shall be no defects, which 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 tensile and compressive forces shall be me

32、asured. NOTE In the case of a tab being made from a highly resilient material (e.g. spring steel or beryllium copper) 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 deformation of that material may tak

33、e place over a period. Furthermore, as the properties of such plastic materials may vary considerably with temperature, 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 sha

34、ll not exceed any value given in the detail specification. 4.2.3 After testing Visual examination according 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. If there

35、 is any damage to the specimen caused by the jaws of a testing machine, this shall not be considered as a defect.

36、ing 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) tensile and compressive forces to be applied and orientation with respect to the tab; e) allowable permanent displacement; f) number of specimens to be tes

37、ted, if other than 3; g) any deviation from the standard test method. _ BS EN 60512-16-17:2008This page deliberately left blankThis page deliberately left blankBSI is the independent national body responsible for preparing British Standards.
