What is Non-Destructive Testing?
Non-Destructive Testing (N.D.T.) is one part of the function of Quality Control and is complementary to other long established methods.

By definition non-destructive testing is the testing of materials, for surface or internal flaws or metallurgical condition without interfering in any way with the integrity of the material or its suitability for service.

The technique can be applied on a sampling basis for individual investigation or may be used for 100% checking of material in a production quality control system.

Whilst being a high technology concept, evolution of the equipment has made it robust enough for application in any industrial environment at any stage of manufacture - from steel making to site inspection of components already in service. A certain degree of skill is required to apply the techniques properly in order to obtain the maximum amount of information concerning the product, with consequent feedback to the production facility.

Non-destructive Testing is not only a method for rejecting substandard material; it is also an assurance that the supposedly good is good. The technique uses a variety of principles; there is no single method around which a black box may be built to satisfy all requirements in all circumstances.
