What does MPI data documentation usually include?

The correct answer highlights the comprehensive nature of Magnetic Particle Inspection (MPI) data documentation. This documentation typically includes inspection results, which provide a summary of the findings from the inspection process. Additionally, it outlines the methods employed during the inspection, ensuring a clear understanding of how the inspection was conducted.

Details regarding equipment calibration are also critical, as they confirm that the tools used were accurate and functioning properly during the inspection. This point is particularly important because proper calibration is essential for reliable results. Finally, operator qualifications are documented to verify that the personnel conducting the inspections are properly trained and certified, ensuring adherence to industry standards and best practices.

Together, these elements create a robust documentation practice that supports the integrity and reliability of the MPI process, making it useful for future reference, audits, or inspections by regulatory bodies. This thorough approach ensures traceability and accountability in the inspection process.
