This practice defines the accepted procedure for performing a statistical analysis on nondestructive testing vs. a data to determine the demonstrated probability of detection (POD) for a specific set of examination parameters. Topics covered include the standard vs. a regression methodology, POD curve formulation, validation techniques, and correct interpretation of results.
Currently there is no specification that addresses this subject. The Air Force has released a Handbook with guidelines on how to fabricate POD specimens and conduct/analyze POD studies using mh1823 POD software. The Handbook is not a requirements document and does not describe the general procedure for analyzing vs. a data and verifying the results for correctness regardless of the software being used to perform the analysis.
