EN 61000-3-2 is applicable to electrical and electronic equipment having an input current up to and including 
16 amps per phase, and intended to be connected to public low-voltage distribution systems. The objective of 
this standard is to set limits for harmonic emissions of equipment onto the AC Power Line.  

 
Basic requirements of the AC source include a ± 2% voltage regulation and a ± 0.5% frequency limit. A low 
distortion sine wave output is required to ensure that the AC source does not adversely contribute distortion to 
the load, meeting the following limits: 

 

o

  0.9% for 3

rd

 order harmonics 

o

  0.4% for 5th order harmonics 

o

  0.3% for 7th order harmonics 

o

  0.2% for 9th order harmonics 

o

  0.2% for even harmonics of order 2 to 10 

o

  0.1% for odd harmonic order from 11 to 40

EN 61000-3-3 is applicable to household appliances and similar electrical and electronic equipment having an 
input current up to and including 16 amps per phase. The objective of this standard is to set limits for voltage 
fluctuations of equipment within its scope, and ensures that home appliances and certain other electrical 
equipment do not adversely affect lighting equipment when connected to the same utility power line. Large 
current variations combined with high utility line power impedance can cause excessive changes in the AC 
supply voltage. If these voltage changes are repeated at short intervals, objectionable fluctuations of luminance 
(flicker) could be generated in illumination sources connected to the same utility line network. 

 
This test requires an AC power source with a standard impedance network and a power analyzer. 
Measurements of steady state and fluctuating harmonics, along with flicker and voltage deviations, are 
conducted using a power analyzer, often called a “flickermeter.”
