- Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage. The field of Nondestructive Testing (NDT) is a very broad, interdisciplinary field that plays a critical role in assuring that structural components and systems perform their function in a reliable and cost effective fashion. NDT technicians and engineers define and implement tests that locate and characterize material conditions and flaws that might otherwise cause planes to crash, reactors to fail, trains to derail, pipelines to burst, and a variety of less visible, but equally troubling events. Because NDT allows inspection without interfering with a product's final use, it provides an excellent balance between quality control and cost-effectiveness. Technology that is used in NDT is similar to those used in the medical industry; yet, typically nonliving objects are the subjects of the inspections.
