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 determine the holding capacity of contacts with resilient features by means of gauges. The test is also applicable to the grounding contact spring, and other similar contact systems, where the ability to retain a gauge is to be demonstrated. In these cases, the component detail specification shall contain sufficient detail, given under 5 d) to f), to enable the test to be done.
