Electromagnetic
environment –guidance
Floors should be wood, concrete
or ceramic tile. If floors are
covered with synthetic material,
the relative humidity should be at
least 30 %.
Power frequency magnetic fields
should be at levels characteristic
of a typical location in a typical
commercial or hospital environ-
ment.
Mains power quality should be that
of a typical commercial or hospital
environment.
Mains power quality should be that
of a typical commercial or hospital
environment.
Mains power quality should be that
of a typical commercial or hospital
environment. If the user of the de-
vice requires continued operation
during power mains interrup-
tions, it is recommended that the
device be
powered from an uninterruptible
power supply or a battery.
