Measurement of DC magnetic, AC magnetic and AC electric fields from 1 Hz to 100 kHz with regard to exposure of human beings - Part 1: Requirements for measuring instruments(IEC 61786-1:2013)
This part of IEC 61786 provides guidance for measuring instruments used to measure the
field strength of quasi-static magnetic and electric fields that have a frequency content in the
range 1 Hz to 100 kHz and with DC magnetic fields to evaluate the exposure levels of the
human body to these fields.
Sources of fields include devices that operate at power frequencies and produce power
frequency and power frequency harmonic fields, as well as devices that produce fields within
the frequency range of this document, including devices that produce static fields, and the
earth’s static magnetic field. The magnitude ranges covered by this standard are 0,1 μT to
200 mT in AC (1 μT to 10 T in DC) and 1 V/m to 50 kV/m for magnetic fields and electric
fields, respectively.
When measurements outside this range are performed, most of the provisions of this standard
will still apply, but special attention should be paid to specified uncertainty and calibration
procedures.
Specifically, this standard
– defines terminology;
– identifies requirements on field meter specifications;
– indicates methods of calibration;
– defines requirements on instrumentation uncertainty;
– describes general characteristics of fields;
– describes operational principles of instrumentation.
