Non-destructive testing (NDT) makes up a group of component testing approaches for examining the serviceability of a part without compromising its stability. In concept, NDT tries to locate defects in a part's surface that forecast future failure before the part fails in service and without jeopardizing the part's energy. Similar to fluorescent dyes, magnetic particle testing employs a layer of fine iron particles applied to a temporarily allured part. Both liquid penetrant and mag particle testing offer a quick, inexpensive means of nondestructive flaw detection, they are both limited to detecting the length and width of a defect.
