No.
The class B FCC limits for conducted disturbance at the mains ports are
lower than EN55022 class B.
QP limits:
FCC - 0.45 to 30MHz = 48dBuV
EN - 0.15 to 0.5MHz = 66 to 56dBuV (decreasing linearly with the log of
frequency)
0.5 to 5MHz = 56dBuV
5 to 30MHz = 60dBuV
Radiated disturbance is performed at 3m for FCC and 10m for EN55022. The
limits and are different.
QP limits:
FCC @ 3m - 30 to 88MHz = 34dBuV/m
88 to 216MHz = 37.5dBuV/m
216 to 960MHz = 40dBuV/m
960 to 1000MHz = 48dBuV/m
EN @ 10m - 30 to 230MHz = 30dBuV/m
230 to 1000MHz = 37dBuV/m
I'm afraid the only way to compare the two standards is to buy copies of
them.
