IEC 61000-4-9 / SANS 61000-4-9
Testing and measurement techniques - Pulse magnetic field immunity test
This standard is mainly applicable to electronic equipment to be installed in electrical plants. At least 5 positive and 5 negative 6.4/16µs pulses applied via an induction coil adequately sized to surround the EUT in three orthogonal positions with a repetition period not less than 10 seconds.
Typical levels are: 100, 300 and 1000A/m
