Test Procedure & Pass/Fail Criteria

Applying the right voltage is only half the test -- how the surge is sequenced, and how the EUT's response is judged afterward, is what actually determines whether a product passes IEC 61000-4-5.

Learning Objectives

📋
Walk through the standard test procedure step by step
🔁
Understand polarity, phase-angle and repetition requirements
✅
Apply Performance Criteria A-D to judge pass/fail
Criterion Definition Result
A Continues to operate as intended, no degradation of performance below specification Pass
B Temporary loss of function or degradation which is self-recoverable Pass (if allowed by product spec)
C Temporary loss of function or degradation requiring operator intervention or system reset Pass (if allowed by product spec)
D Loss of function or degradation which is not recoverable due to damage to hardware, software, or loss of data Fail

Select what happened to the EUT during and after the surge to see which criterion applies.

The diagram asks three sequential questions -- did the EUT keep operating normally, did it recover on its own, and did it recover after a reset or operator action -- to walk down to the matching Performance Criterion (A-D). The highlighted path shows the route for the outcome selected above.
