Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components, or physical systems for unexpected irregularities, without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used.
In contrast to NDT, other tests are destructive in nature and are therefore done on a limited number of samples (“lot sampling”), rather than on the materials, components, or systems actually being put into service.
