1 SCOPE
This Part of GB/T 21437 establishes a bench test method for the evaluation of the immunity of devices under test (DUTs) to transient transmission by coupling via lines other than supply lines. The test transient pulses simulate both fast and slow transient disturbances, such as those caused by the switching of inductive loads and relay contact bounce.
Only one test method need be selected for slow transients and only one method need be selected for fast transients.
