Rich, 

The 75W exemption may be true for 61000-3-2 but certainly not for 61000-3-3. 
Unfortunately, it seems to be not well understood by many laboratories as
well. I have many reports issued by well-known accredited labs with this 75W
statement on 61000-3-3.

Regards, 
Kris

Subject: Exemption from Flicker Testing 



Clause 6.1 of EN 61000-3-3 + A1 says "Tests shall not be made on equipment 
which is unlikely to produce significant voltage fluctuations or flicker. It 
may be necessary to determine, by examination of the circuit diagram and 
specifications of the equipment and by a short functional test, whether 
significant voltage fluctuations are likely to be produced." 

Am I standing on firm ground assuming that equipment consuming less than 75W 
can be exempted from test?
