Description ASNT study guides provide prospective ASNT Level III examinees with enough technical knowledge to pass an ASNT NDT Level III examination. Intended to be used with a comprehensive NDT text, such as volumes from the Nondestructive Testing Handbook series. This magnetic particle testing (MT) book was updated in 2013 to align with the new ASNT Standard Topical Outlines for Qualification of Nondestructive Testing Personnel (ANSIASNT CP1052011). Several sections have been expanded including the sections on UV light, indications, surface discontinuities, welding discontinuities, subsurface discontinuities and interpretations, and on UV light hazards. Many new chapter review questions were added.
