17.2 Block Diagram of Test Setup
17.3 Test Setup and Test Procedure
The surge is to be 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 so that the specified wave may be developed on the lines under test.
The EUT was arranged and connected according to its functional requirements
The EUT was placed on a 0.8m high wooden table, standing on a ground reference plane 2.6m by 1.8m
in size, supplied by the coupling-decoupling network (Best EMC). arranged and connected to satisfy its
functional requirement and the power code between the EUT and the
coupling/decoupling network was less than 2 meters.

18.3 Test Setup and Test Procedure
The EUT was placed on an insulating support of 0.1m height above a ground reference Plane,
arranged and connected to satisfy its functional requirement.
arranged and connected to satisfy its functional requirement.
All relevant cables were provided with the appropriate coupling and decoupling
devices at a distance between 0.1m and 0.3m from the projected geometry of the EUT on an
insulating support of 0.03m height above the ground reference plane.
The frequency from 0.15MHz to 230MHz was checked.

Notes:
1.“*” for 0.5 period, the test shall be made in positive and negative polarity, i.e.
starting at 0
° and 180°, respectively
2. “**” means “x” is an open duration. This duration can be given in the product
duration between ½ a period and 3000 periods, but duration less than 50 periods
are most common.
3. if the EUT is tested for voltage dips of 100%, it is generally unnecessary to test for
other levels for the same durations. However, for some cases(safeguard systems or
electro-mechanical devices) it is not true. The product specification or product
committee shall give an indication of the applicability of this note.
