(read : make it cheaper)
ASNT also defines the requirements for personnel to be qualified to perform and interpret examination results, and graded in 'levels'. Level 2 is generally the qualifications for persons performing the tests. Radiography is divided into two personnel, persons doing the radiography, and persons reading the film.
The common disciplines are MT (Magnetic Particle Inspeciton) PT (Penetrant Inspection) RT (Radiographic Inspection) and Yes, VT (Visual Inspection) This is the one that surprises a lot of people, but it's amazing how seeing the same thing can be so differently interpreted.
Geez I love retirement.
