Scope

This Part relates to the immunity requirements of equipment, only under operational
conditions, to magnetic disturbances at power frequency related to:
- residential and commercial locations;
- industrial installations and power plants;
- medium voltage and high voltage sub-stations.
The applicability of this standard to equipment installed in different locations is
determined by the presence of the phenomenon, as specified in clause 3.
This Part does not consider disturbances due to capacitive or inductive coupling in
cables or other parts of the field installation.
Other standards dealing with conducted disturbances cover these aspects.
The object of this Part is to establish a common and reproducible basis for evaluating
the performance of electrical and electronic equipment for household, commercial and
industrial applications when subjected to magnetic fields at power frequency
(continuous and short duration field).
The Part defines:
- recommended test levels;
- test equipment;
- test set-up;
- test procedure.
Other kinds of magnetic fields shall be object of standardization:
- fields at other power frequencies (16 2/3 Hz ~ 20 Hz or 30 Hz ~ 400 Hz);
- fields of harmonic currents (100 Hz ~ 2 000 Hz);

Summary	This standard specifies the operating conditions of the equipment on the following places of power frequency magnetic field immunity requirements harassment: residential and commercial areas, industrial and mining enterprises and power plants, medium voltage, high voltage substations. The installation of the devices in different locations, the applicability of this part by the third of the phenomena noted in chapter may be. This section does not consider site facilities in the cable or other parts of the capacitive and inductive coupling caused by the harassment. Conducted disturbances related to this consideration in other standards. The purpose of this section is to establish a common and reproducible with a benchmark to evaluate the in -frequency (continuous and short) in a magnetic field domestic, commercial and industrial electrical and electronic equipment performance. This section provides the following: The recommended test levels, test equipment, test arrangement, test procedures. For other types of magnetic fields will also develop standards
