Table of Content


Non-destructive Testing (NDT) is a combination of various inspection techniques used individually or collectively to evaluate the integrity and properties of a material, component, or system without causing damage to it.

In other words, the part that requires the use of one or more of those techniques can still be used once the inspection process is over.

Non-destructive Testing (NDT) is therefore often used for the detection, characterization, and sizing of inherent discontinuities, as well as those associated with damage mechanisms.

NDT is regulated by Codes and Standards according to the type of industry, country, and other criteria.

American Society for Mechanical Engineers (ASME), ASTM International, COFREND, CSA, Canadian General Standards Board (CGSB), and American Society For Nondestructive Testing (ASNT), etc. are well-known examples.
