Methods of Measurement of Magnetic Fields in Vehicles for Assessment of Occupant Exposure, 1 Hz to 300 kHz
The test procedures in this SAE Recommended Practice are applicable to the measurement of human exposure to magnetic fields in passenger vehicles, in the frequency range 1 Hz to 300 kHz. The measurements survey magnetic fields at the typical occupant head and trunk positions. The definition of limits is outside the scope of this document, as are methods of calculation of induced body currents and electric fields, calculation of "coupling factors" for non-uniform exposure, and relaxation of limits for exposure of limbs.
