Onderwerp:      EN55013 Question.

Hello EN55013 Experts,

        I have been reviewing EN55013 and think I understand most of it, 
however I have a question that perhaps someone in the group can answer.
        Clause 3.2 of EN55013 (I have the 1990 version) is titled "Limits of 
mains terminal disturbance voltage" and includes this paragraph: 
"If the measurements with the quasi-peak detector give values equal or less 
that the limits for the measurement with the average detector, then the limit 
for the measurement with the average detector need not be carried out."
        I understand that this clause applies to conducted emission 
measurements.
        My question is this; does the paragraph quoted above apply to Clauses 
3.3 through 3.5 as well?  The way Clauses 3.3 through 3.5 are written it is my 
guess that it does not since it appears that the paragraph in Clause 3.2 is not 
referred to by any of the other clauses.  
        If my guess is correct, then that would indicate that I can chose 
either the quasi-peak or the average measurement method for performing tests in 
accordance with Clause 3.5 without having to use the average measurement method 
as a final check.
        Is this the common interpretation and understanding?  Just doing a 
sanity check...
