19、 16n: Bending strength, fixed male tabs 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing connectors within the scope of IEC technical committee 48. It may also be used for similar devices when specified in a detail specification. The object of

20、 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 bending stress. If so specified in the detail specification, forces other than bending may be applied. 2 Normative references The following referenced docu

22、 1-1: General examination Test 1a: Visual examination 3 Preparations 3.1 Preparation of specimen The specimen shall consist of a connector fitted with one or more male tabs. They may be wired if so specified in the detail specification. Any preconditioning given in the detail specification shall be

23、applied. Three such specimens shall be prepared. 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). NOTE If

24、 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 BS EN 60512-16-14:200860512-16-14 IEC:2008 5 3.3 Mounting If mounting of the specimen is appropriate, it shal

26、Test method 4.1 General A single force P shall be applied to the fixed tab according to Figure 1. The force shall be steadily increased from zero to that specified in the detail specification. This force shall be maintained for 1 minute. The force shall be removed, and the (permanent) displacement o

27、f the tab shall be measured. Permanent displacement is defined as the difference between the initial position of the tab before application of any force and its position after all force is removed. This shall be repeated, on an adjacent (new) tab, with the force being applied in the opposite directi

28、on. At least 10 tabs shall be selected at random from the 3 specimens, of these, at least one tab shall be near the periphery, and one, at or near, the centre of the connector insert or housing. For inserts or housings having 3 or less tabs, all tabs shall be tested. 4.2 Measurements and requirement

29、s 4.2.1 Before testing Visual examination according to IEC 60512-1-1 shall be carried out. There shall be no defects, which would impair the validity of the test. BS EN 60512-16-14:2008 6 60512-16-14 IEC:2008 4.2.2 During testing The deflection and permanent displacement of the component, measured a

30、t the application point of the force, shall be recorded. 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,

31、 recovery of deformation of that material may take 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), any deviation from this should be given in the relevant detail

32、specification. The permanent set shall 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 may be judged by a mating t

33、est with its counterpart 5 Details to be specified When this test is required by a detail specification, the following shall be given 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 re

34、quired; d) force to be applied and orientation with respect to the tab; e) allowable permanent set; f) number of specimens to be tested, if other than 3; g) any deviation from the standard test method. _ BS EN 60512-16-14:2008This page deliberately left blankBSI is the independent national body resp
