Measurement of low-frequency magnetic and electric fields with regard to exposure of human beings - Special requirements for instruments and guidance for measurement

Scope

Provides guidance for measuring the values of magnetic and electric fields with regard to exposure of human beings. The frequency range spans 15 Hz to 9 kHz. The standard covers magnetic fields with magnitudes from 100 nT to 100 mT, and electric fields from 1 V/m to 50 kV/m. Sources of fields include devices that operate at power frequencies and produce frequency harmonics. Other devices produce fields independent of the power frequencies.
