Dear All, I am not an emc expert but can definitely say that such multiple testing is a barrier to trade and will open a can of worms in other countries; imagine Japan requiring test at 100 Vac 50 and 60 Hz, Taiwan requiring tetsing at 220 V, 60 Hz, Malaysia requiring test at 240 V, 50 Hz and so on.

Both FCC & CE insists that conducted emission testing is required for this kind of devices, with emissions measured at the a.c input side. Is it necessary to run 2 tests, one with a 230 volts 50 Hz a.c supply (for CE) and the other with 110 volts 60 Hz a.c supply (for FCC)?
