Criterion A: Normal performance during and after test.
Criterion B: For EFT and surges, low-voltage protection or reset is not allowed. Temporary output
voltage fluctuation ceases after disturbances ceases, and from which the EUT recovers its normal
performance automatically.
For Dips and ESD, output voltage fluctuation or reset is allowed during the test, but recovers to its
normal performance automatically after the disturbance ceases.
Criterion C: Temporary loss of output, the correction of which requires operator intervention.
Criterion D: Loss of output which is not recoverable, owing to damage to hardware.
