FCC Pt15 states that you can use their limits or, alternatively, the limits found in CISPR 22:1995. Your EN Class B data should be sufficient for having your lab generate an FCC B (or A) report.

FCC Part 15 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.
