Main Procedure

Discard all the parts that fail the Non-Destructive Inspection (NDI) criteria.

Magnetic Particle Inspection (MPI)

Do a Magnetic Particle Inspection (MPI) for the applicable parts, in accordance with the 505-CMM and in the BHT-ALL-SPM, Chapter 6, Standard Practices Manual.

Fluorescent Penetrant Inspection (FPI)

Do a Fluorescent Penetrant Inspection (FPI) for the applicable parts, in accordance with the 505-CMM and in the BHT-ALL-SPM, Chapter 6, Standard Practices Manual.

Requirements After Job Completion

Use a gauss meter to make sure magnetization of the parts is less than 3 gauss anywhere on the part. Otherwise, demagnetize the part per the instructions contained in the BHT-ALL-SPM, Chapter 6, Standard Practices Manual.
