IEC60884-1:2022 Clause 24.9 Mechanical Test on  Shutters with 0-75N force

Shuttered socket-outlets shall have the shutter so designed that it withstands the mechanical force which may be expected in normal use, for example when a pin of plug is inadvertently forced

against the shutter of a socket-outlet entry hole.

One pin from a plug of the same system is applied for 1 min with a force of 40N against the shutter of an entry hole in a direction perpendicular to the front surface of the socket-outlet.

For shutters provided as the only means to prevent single pole insertion, the force shall be 75N instead of 40N.

Where the socket-outlet is designed to accept plugs of different types, the test is carried out with a pin from a plug with the largest size pin.

The pin shall not come into contact with live parts.
