Hallo Günter J. Maass, a simple question, did you ever get any answer?
As far as I read the standard it is not written if the limits are peak or rms. But it is written that the limits are applicable to equipment intended to be conencted to 220/380 V, 230/400 V and 240/415 V. Written without rms. This is to me an indication that too the limits are in rms. The limits for Class C equipment are given in percentage of the input current at the fundamental frequency. To me it would be most logical if the limits are rms values, if/when/as the input current at the fundamental frequency is given in rms. EN 61000-3-2 § 6.2.2 says: "......However, for transitory even harmonic currents of order from 2 to 10 and transitory odd harmonic currents of order from 3 to 19, values up to 1,5 times the limits in tables 1 to 3 are allowed for each harmonic during a maximum of 10 % of any observation period of 2,5 min." I think this is a kind of taking care of occasional peak currents.
