26、2011 5 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 9-3: Endurance tests Test 9c: Mechanical operation (engaging and separating) with electrical load 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing connectors within the sco

27、pe of IEC technical committee 48. This test may also be used for similar devices when specified in a detail specification. The object of this standard is to define a standard test method to assess the mechanical and electrical operational endurance, i.e. engaging and separating cycles, of a connecto

28、r in an operating mode which includes a specified electrical load. 2 Normative references The following referenced documents are indispensable for the application of this document.
