This part of IEC 60512, when required by the detail specification, is used for testing connectors within the scope of 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 the means by which an oversize male contact, or other similar object, is prevented from entering the equivalent female contact. NOTE Although this test is particularly applicable to cylindrical contacts, the use for contacts with other geometries is not excluded. In which case, the detail specification should contain sufficient detail, given under 5.e), to enable the test to be done.
