16、terminations Test 16k: Stripping force, solderless wrapped connections 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 technical committee 48. It may also be used for similar devices when specif

17、ied in a detail specification. The object of this part of IEC 60512 is to detail a standard test method to determine ability of a component to resist forces that might strip a wrapped connection from its post along the axis of the post. Such wrapped connections are described in IEC 60352-1. NOTE Thi

18、s test is considered as destructive to specimens used. 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 document (includ

19、ing any amendments) applies.

20、1 Preparation of specimen The specimen shall consist of a wrap post with a wrapped connection as described in the detail specification. The wrap post may be cut off from a component. Any pre-conditioning of the samples required by the applicable detail specification shall be applied. 3.2 Equipment A

21、 holding device and stripping tool, such as those shown in Figure 1 shall be provided. Clearance shall exist between the post and the test fork. The total clearance shall not exceed 50 % of the diameter of the wrapping wire. Figure 1 also gives an example of sample mounting. BS EN 60512-16-11:2008 3

23、onnection so as to move the whole connection along the axis of the wrap post. The movable part of the test device shall travel steadily, at a speed between 25 mm/min to 50 mm/min. The test shall continue until the whole wrapped connection has moved along the axis of the post for a distance of approx

24、imately equal to one diameter of the wrapping wire. 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, nor any features, or other items, which would impair the validity of the test. 4.2.2 During testin

25、g The peak force required to achieve the specified movement of the wrapped connection shall be recorded. It shall not be less than that given in the detail specification. The rate at which the stripping force was applied shall be recorded. 5 Details to be specified When this test is required by the

26、detail specification, the following details shall be specified: a) whether preconditioning is required; b) details of the specimen; NOTE Geometrical, metallurgical and surface finish details of the post and wire as well as tooling and application details, are considered essential c) number of specim

27、ens to be tested; d) the minimum allowable peak force required to achieve the specified movement; e) any deviation from the standard test method. _ BS EN 60512-16-11:2008 5 Annex ZA(normative) Normative references to international publications with their corresponding European publications The follo
