This part of IEC 61300 describes the test procedure to test the wind resistance of a protective housing and its mounting hardware using the fastening parts recommended by the manufacturer. The protective housing is considered to have a cuboid shape.
The applied force in this test procedure simulates a steady wind load from each direction to a protective housing and its mounting hardware fixed to a support.
