Severity Scale

Scale of Occurrence

Non-detection scale

1

No influence for failure

Failure very unlikely

Accurate detection during inspection

2

Decline in yield

Failure unlikely

High probability of detection during control

3

Slight system corruption

Possible failure

Moderate probability of detection during control

4

System Shutdown

Inevitable failure

Low probability of detection during control

5

System jeopardy

Very Probable Failure

Impossibility of detection during control
