IEC60065 Figure 11Test Apparatus For Devices Forming A part Of The Mains Plug
Device forming a part of the mains plug
A device provided with pins intended to be introduced into fixed socket-outlets shall not impose undue strain on these socket-outlets.
Compliance is checked by engaging the device, as during intended use, with the socket-outlet of a test apparatus as shown in figure 11. The balancing arm of the test apparatus pivots about a horizontal axis through the centre lines of the contact tubes of the socket-outlet at a distance of 8 mm behind the engagement face of the socket-outlet.
With the device not in engagement, the balancing arm is in equilibrium, the engagement face of the socket-outlet being in the vertical position.
After the device has been engaged, the torque to be applied to the socket-outlet to maintain its engagement face in the vertical plane is determined by the position of a weight on the balancing arm. The torque shall not exceed 0.25 Nm.
Note: This test is compatible with the test described in the IEC 60884-1.
