BS EN 61000-4-8:2010 Electromagnetic compatibility (EMC). Testing and measurement techniques. Power frequency magnetic field immunity test

BS EN 61000-4-8 relates to the immunity requirements of equipment, only under operational conditions, to magnetic disturbances at power frequencies 50 Hz and 60 Hz related to:

– Residential and commercial locations;
– Industrial installations and power plants;
– Medium voltage and high voltage sub-stations.

BS EN 61000-4-8 does not consider disturbances due to capacitive or inductive coupling in cables or other parts of the field installation.

The object of BS EN 61000-4-8 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 standard defines:

– Recommended test levels
– Test equipment
– Test set-up
– Test procedure.
