Magnetic particle inspection (MPI) is a type of non-destructive testing (NDT) that is utilized to detect surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. MPI is critical technology that is used to maintain and support various equipment throughout the Air Force. Typical MPI units consist of an induction coil, a tank to hold suspension and particles, and a booth with a hood to remove light. MPI works by either directly or indirectly magnetizing a material. Magnetic particles in either dry or wet suspension are then applied to the magnetized material. If the material has a surface or subsurface discontinuity magnetic flux will be leaked. Magnetic particles will be attracted to the flux leakage indicating the discontinuity to the user.

-- Telephone support, at a minimum, shall be provided for installation of equipment during the warranty period.
