NOTE As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC.
As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity
test standard should be applied or not, and if applied, they are responsible for determining the appropriate test
levels and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees
in the evaluation of the value of particular immunity tests for their products.
This standard defines:
– a range of test levels;
– test equipment;
– test setups;
– test procedures.
The task of the described laboratory test is to find the reaction of the EUT under specified
operational conditions, to surge voltages caused by switching and lightning effects at certain
threat levels.
It is not intended to test the capability of the EUT's insulation to withstand high-voltage stress.
Direct injections of lightning currents, i.e, direct lightning strikes, are not considered in this
standard.อ
