Requirements and Test Procedure:
Socket-outlets shall withstand the lateral strain imposed by equipment likely to be introduced into them.
For socket-outlets having ratings up to and including 16 A and 250 V, compliance is checked by means of the device shown in figure 13.
Each specimen is mounted on a vertical surface with the plane through the socket-contacts horizontal. The device is then fully engaged and a weight hung on it such that the force exerted is 5 N.
The device is removed after 1 min and the socket-outlet is turned through 90° on the mounting surface. The test is made four times, the socket-outlet being turned through 90° after each engagement.
During the test the device shall not become disengaged from the socket-outlet.
After the tests, the socket-outlets shall show no damage within the meaning of this standard; in particular, they shall comply with the requirements of clause 22.
