5.5 ELECTRICAL FAST TRANSIENT/BURST IMMUNITY TEST 
5.5.1 TEST SPECIFICATION 
Basic Standard 
EN 61000-4-4: 2012 
Test Voltage 
Electrical Fast Transient/Burst – EFT: 
AC Power Port: ±1kV,Signal port ±0.5kV 
Performance Criterion B 
Polarity 
Positive and Negative 
Impulse Frequency 
5 kHz 
Impulse Wave-shape 
5 ns/50ns for voltage  
Burst Duration 
15 ms 
Burst Period 
300 ms 
Test Duration 
2 minutes 
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.
