What information is critical to document when conducting MPI?

Documenting the date, time, types of tests conducted, results, and inspector signatures is essential in Magnetic Particle Inspection (MPI) for several reasons. This comprehensive documentation ensures traceability and accountability for the inspection process.

The date and time provide a clear timeline of when the inspection was performed, which is crucial for maintenance records and compliance with industry standards. Knowing when the inspection took place helps track the service life of components and the frequency of inspections, which is vital for safety and regulatory purposes.

Recording the types of tests conducted allows for an understanding of the methods used during the inspection. Different methods might be more or less effective depending on the material, geometry of the part, and specific conditions, and having a record of these tests can inform future inspections and practices.

The results are the most critical part of the documentation as they indicate whether defects were present and the state of the part being inspected. Accurate results aid in decision-making regarding repair, rejection, or further testing of components.

Lastly, the inspector's signature signifies that the inspection was conducted by a qualified individual and verifies that the documented information is correct. This signature ensures accountability and quality control within the inspection process.

In summary, documenting these specific pieces of information during MPI is vital to ensure operational integrity,
