EN 55024 specifies the IEC 61000-4-4 Standard as the basic procedure for electrical fast transient testing. IEC 

61000-4-4 (2004) 

 

defines the immunity requirements and test methods for equipment that are required to withstand high-voltage 

transients coupled on supply, signal and control ports.  The standard configuration for “type tests” outlined in 

IEC 61000-4-4 (2004) 

 is 

used.  For further information, please refer to the technical sections in the IEC 61000-4-4 (2004) 

 in 

addition to the test results section and photographs of the test set-up provided in this report.  

 

For electrical fast transient/burst tests, EN 55024 requires that the EUT meet at least performance Criterion B 

for ± 1 kV Power line and ± 0.5 kV signal line transients.

EN 55024 specifies the IEC 61000-4-5 Standard as the basic procedure for power line surge immunity tests.  

This standard relates to the immunity requirements, test methods, and range of recommended test levels for 

low voltage equipment to unidirectional surges caused by over-voltages from switching and lightning 

transients.  The standard configuration as outlined in IEC 61000-4-5 (2001) 

 , 

section 7 was used. 

 

Each device was tested in a total of three surge configurations: 

 
Surge #1: Combination Wave, Line to Protective Earth with 9uF and 10Ohm, common mode, generator 

earthed. 

Surge #2: Combination Wave, Neutral to Protective Earth with 9uF and 10Ohm, common mode, 

generator earthed. 

Surge #3: Combination Wave, Line to Neutral with 18uF, differential mode, generator floated. 
 

For further information, please refer to the technical sections in the IEC 61000-4-5 (2001) 

  

in addition to the test results section and photographs of the test set-up provided in this report. 

 

For Power line surge tests, the EUT meet at least performance Criterion B for ±2kV common mode and ±1kV 

differential mode surges in the AC power supply configuration.
