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.
