22、 8c: Robustness of actuating lever 1 Scope and object This part of IEC 60512, when required 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
23、 standard is to detail a standard test method to assess the robustness of the actuating lever of a connector mating or release mechanism. 2 Normative references The following referenced documents are indispensable for the application of this document.

26、ail specification. Unless otherwise specified, the specimen shall be mounted in the normal manner, using the normal panel or chassis cut-out as laid down in the detail specification. NOTE The plate should be strong enough to sustain the applied forces. The length and width of the plate should be suc
27、h that the contour of the specimen is exceeded. Equipment 3.2A suitable test tool (e.g. a universal materials testing machine) and appropriate adapters shall be used. Mounting 3.3Unless otherwise specified, the specimen shall be mounted in the normal manner, using the normal panel or chassis cut-out
28、 as laid down in the detail specification. BS EN 60512-8-3:2011 6 60512-8-3 IEC:2011 NOTE The plate should be strong enough to sustain the applied forces. The length and width of the plate should be such that the contour of the specimen is exceeded. 4 Test method Force 4.1A specified force shall be
29、applied at the tip of the actuating lever. This force shall be applied in each of the following directions (see Figure 1): perpendicular to the lever axis and in the plane of lever travel and at each end position of the lever (Fa1and Fa2); perpendicular to the lever axis and perpendicular to the pla
30、ne of lever travel at each position of the lever (Fb1and Fb2); axially with the lever axis towards the lever pivot (Fc); axially with the lever axis away from the lever pivot (Fd). The force shall be steadily increased at a rate of approximately 20 N/s up to the specified value and maintained for 1

NOTE if applicable, the detail specification may require a sealing test from the IEC 60512-14 series or an ingress protection test according IEC 60529. 6 Requirements There shall be no damage which would impair normal operation. 7 Details to be specified When this test
33、 is required by the detail specification, the following details shall be specified: a) mounting details, including dimensions of the panel cut-out; b) shape of the fixture or tool used for applying the force/torque; c) force/torque to be applied, direction and rate of application; d) requirements fo
