ANSI/IEEE C95.1 is for human exposure but it does not cover pacemakers. Draft VDE0848 part 2 (1991) covers 30 kHz-300Ghz and does have limits for pacemakers. An English translation is available from BSI.
There is no relationship between the limits for human exposure and limits for pacemakers. The limits for human exposure are based upon induced current density at the lower frequencies and SAR at the higher frequencies. The limits for pacemakers are based upon the induced voltage in the lead. The ANSI limits are as follows: 3kHz-100kHz: 614V/m and 163A/m 100kHz-3MHz: 614V/m and 16.3/f A/m where f is in MHz the limits are based upon SAR, so the square of values are averaged over any 6 minute period.

What is the ANSI standard or regulation for safe limits for people exposed to electromagnetic fields? How about people with pacemakers? I've been informed that there may have been a German study done in 1988 concluding that these field limit values could be used in testing the pacemaker immunity. Can anyone help me to get these ANSI values, at least for the magnetic fields below 400 kHz?
