g) At least ten single discharges (in the most sensitive polarity) were applied to the center of one
vertical edge of the Vertical Coupling Plane (VCP) in sufficiently different positions that the four
faces of the EUT were completely illuminated. The VCP (dimensions 0.5m * 0.5m) was placed
vertically to and 0.1 meters from the EUT.

5.4.2 TEST PROCEDURE
The EUT and its simulators shall be placed 0.1m high above the ground reference plane which is a min.
1m×1m metallic sheet with 0.65mm minimum thickness. This reference ground plane shall project
beyond the EUT by at least 0.1m on all sides and the minimum distance between EUT and all other
conductive structure, except the ground plane beneath the EUT, shall be more than 0.5m.
For input and AC power ports:
The EUT is connected to the power mains by using a coupling device which couples the EFT
interference signal to AC power lines. Both polarities of the test voltage should be applied during
compliance test and the duration of the test can’t less than 1min.
