3.11.  Electrical Fast Transient Immunity: IEC 61000-4-4 (2004) 
 
 
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.
