5.8.3 TEST PROCEDURE 
The EUT and support equipment, are placed on a table that is 0.8 meter above a metal ground 
plane measured 1m*1m min. and 0.65mm thick min.   
The other condition as following manner: 

a. The length of power cord between the coupling device and the EUT should not exceed 1 

meter. 

b. Both positive and negative polarity discharges were applied. 

c. The duration time of each test sequential was 1 minute 

d. For the actual test configuration, please refer to the related Item –Block Diagram of system 

tested (please refer to 3.3).

Note: 
TABLE-TOP EQUIPMENT   

 

The configuration consisted of a wooden table (0.8m high) standing on the Ground Reference 
Plane. The GRP consisted of a sheet of aluminum (at least 0.25mm thick and 2.5m square) 
connected to the protective grounding system. A minimum distance of 0.5m was provided 
between the EUT and the walls of the laboratory or any other metallic structure. 
FLOOR-STANDING EQUIPMENT 
The EUT installed in a representative system as described in section 7 of IEC 61000-4-4 and its 
cables, were isolated from the Ground Reference Plane by an insulating support that is 0.1-meter 
thick. The GRP consisted of a sheet of aluminum (at least 0.25mm thick and 2.5m square) 
connected to the protective grounding system.

Note:  

 

1) P/N denotes the Positive/Negative polarity of the output voltage. 

 

2) N/A - denotes test is not applicable in this test report 

 

3) Criteria A: There was no change operated with initial operating during the test. 

 

4) Criteria B: The EUT function loss during the test, but self-recoverable after the test. 

 

5) Criteria C: The system shut down during the test.
