This international standard relates to the immunity requirements of equipment, only under operational conditions, to pulse magnetic disturbances mainly related to:
- 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 standard does not consider disturbances due to capacitive or inductive coupling in cables or other parts of the field installation.
Other IEC standards dealing with conducted disturbances cover these aspects.
The object of this standard 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 pulse magnetic fields.
The standard defines:
- recommended test levels;
- test equipment;
- test set-up;
- test procedure.
