MPI Test

Magnetic Particle

Magnetic Particle Inspection (MPI) is a widely used non-destructive testing technique, used for the detection of surface and shallow subsurface defects, in materials which can be strongly magnetised - such as iron, nickel and cobalt. It is primarily used for crack detection.

Fluorescent MPI Test

Testa supplies Magnetic testing to numerous fabrication and engineering companies. We can carry out colour contrast type or fluorescent type techniques. Fluorescent particles viewed under a UV light allows for greater clarity, when a higher sensitivity is required during an MPI test.

At Testa, all the NDT technicians we use, are qualified to industry recognised PCN (personnel certification in non-destructive testing) in accordance with BS EN ISO 9712.
