20、red 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 this part of IEC 60512 is to detail a standard test method to assess the effectiveness of co
21、ntacts to resist deformation (damage) from crimping operations. Although this test is intended for cylindrical contacts, especially machined contacts, it is applicable to contacts with other geometries and construction. In which case, the detail specification shall contain sufficient detail, given u
22、nder clause 4, to enable the test to be done. 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 (including any a
23、mendments) 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 consist of contact-wire assemblies. The length of cable protruding from the contact sh
24、all be at least 100 mm. Number of specimens: 10 specimens for each barrel size (5 for the minimum wire size and 5 for the maximum wire size) unless otherwise specified in the detail specification. The crimping tool(s) shall be those specified in the detail specification. If none are so specified, th
25、e contact manufacturers instructions for tooling shall be followed. In any case, full details of tooling shall be given in any reports supporting claims of conformance to this part of IEC 60512. Any preconditioning given in the detail specification shall be applied. BS EN 60512-16-7:200860512-16-7 I
26、EC:2008 5 3.2 Equipment A mounting collet shall be provided such that the contact may be rotated around its longitudinal axis to permit measurements at the specified points. The precision of the collet shall be such that the run-out of a steel gauge pin of 1,5 to 2,0 mm diameter measured 10 to 15 mm
27、 from the collet face shall not exceed 0,1 % of such distance. 4 Test procedure The contact shall be held in a collet in region H as shown in Figure 1, so that the contact can be rotated around the longitudinal axis to permit measurements at the specified points. A suitable test arrangement is shown
28、 in Figure 2. In the case of cylindrical contacts, readings (preferably with an indicator gauge) of the position of the contact shall be taken before and after crimping. The total excursion of the position when the contact is rotated is halved to give the deformation (or damage). Non-circular contac
29、ts shall be measured in a similar manner. The deformation (or damage) may be similarly calculated. MX YHIEC 1005/08 Key X Twice the male contact diameter. Also used for corresponding female contact OR If not circular, corresponding characteristic dimension of each contact. Y Mid point between end of
30、 crimp barrel, or end of contact, and beginning of crimp indentation M Measurement points for contact deformation H (Example of) Holding area NOTE This should correspond to the area in which the contact is intended to be held in use.

The
32、re shall be no defects that would impair the validity of the test. 5.2 After testing The requirements of the detail specification for deformation shall be met. Visual examination according to IEC 60512-1-1 shall be carried out. There shall be no defects, other than any found under 5.1, that would im
33、pair the normal functioning of the component. 6 Details to be specified When this test is required by the detail specification, the following details shall be specified. a) wire type and size; b) specification of crimping tool(s) to be used; c) area(s) of contact to be held by the mounting collet; N
34、OTE This should correspond to the housing or insert location point(s). d) points of measurement on the contact; if other than those given in 3.2; e) values of deformation permitted, for each point of measurement; f) number of specimens to be tested if different than specified in 3.1; g) any deviatio
35、n from the standard test method.
