There exists a nice guidance from EPSAM (European Power Supply 
Manufacturer Association) about Harmonics requirements. (sorry, it's 
only in German language so far): 

EN60601 does not include harmonics requirements.

There are discussion , if  harmonics requirements might be 
implemented for medical for home therapie and non hospiatl use.  But 
this might take a long time in Europe....

 Horst

My copy of IEC601-1-2 (Medical EMC compatibility, First edition) says
there are no requirements for harmonic distortion (paragraph 36.201.2.1).
Is this still correct today?  Are there plans to incorporate this
requirement in the future?
