    Abstract - (Show below) - (Hide below)

    Establishes a common and reproducible basis for evaluating the performance of electrical and electronic equipment for household, industrial and commercial applications when subjected to magnetic fields at power frequency. Does not consider disturbances due to capacitive or inductive coupling in cables or other parts of the field installation. Gives detailed definitions, diagrams and annexes.
