Any reports, such as Material Test Reports, that have been modified or corrected should be:

The correct answer isAbecause, in source inspection practice, a corrected or revised report isnot automatically invalidif the change is properly explained, traceable, and supported by the manufacturer’s quality system. The source inspector’s role is to review documentation for accuracy, traceability, consistency with specifications, and objective evidence of compliance. If a Material Test Report or similar record has been modified, the proper action is to obtainclarification, verify the reason for the correction, and confirm that the revised record remains authentic and controlled. Immediate rejection is too extreme unless there is evidence of falsification, loss of traceability, or unauthorized alteration.

This aligns with the API guide’s emphasis onsource inspection and quality surveillance activitiesrather than arbitrary dispositioning, and on verifying compliance through documented evidence and surveillance of the manufacturer’s process. The guide is intended as a resource for the API Source Inspector Electrical Equipment body of knowledge, which includes document review, inspection planning, surveillance, and record verification as part of the overall source inspection process. Therefore, corrected reports should beaccepted after clarification and verification, not rejected solely because they were revised.
