5.5.2 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.

5.6.2 TEST PROCEDURE
a) For EUT power supply:
The surge is applied to the EUT power supply terminals via the capacitive coupling network. Decoupling
networks are required in order to avoid possible adverse effects on equipment not under test that may be
powered by the same lines, and to provide sufficient decoupling impedance to the surge wave. The power
cord between the EUT and the coupling/decoupling networks was shorter than 2 meters in length.

cord between the EUT and the coupling/decoupling networks was shorter than 2 meters in length.
b) For test applied to unshielded un-symmetrically operated interconnection lines of EUT: The surge was
applied to the lines via the capacitive coupling. The coupling / decoupling networks didn’t influence the
specified functional conditions of the EUT. The interconnection line between the EUT and the
coupling/decoupling networks was shorter than 2 meters in length.

c) For test applied to unshielded symmetrically operated interconnection / telecommunication lines of
EUT:The surge was applied to the lines via gas arrestors coupling. Test levels below the ignition point of
the coupling arrestor were not specified. The interconnection line between the EUT and the
coupling/decoupling networks was shorter than 2 meters in length.
