Proof Test Coverage Determination
How to Determine Proof Test Coverage
The following are examples of how proof test coverage can be estimated:
•
Manufacturers guidance.
•
Failure Mode and Effects Analysis (FMEA) / Failure Mode Effects and Diagnostic
Analysis (FMEDA) whereby a specific test has been considered.
•
Reviewing failures encountered during operation and identifying how many would
have been detected by the defined proof test.
•
Identifying failures modes and failure mode distribution from a data source e.g.
OREDA, FARADIP, SINTEF, etc. and identifying which of these failure modes would
be detected by the defined proof test.
•
Engineering judgement based on sound evidence.
