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
characteristics of a typical location in a typical commercial
or hospital environment.
