Non-destructive testing (NDT) involves a variety of analysis techniques used to evaluate materials and components without damaging them. NDT detects abnormalities in physical, chemical, or electrical properties and provides advantages over destructive testing by being fast, inexpensive, and easy while allowing future use of the tested objects. NDT technicians and engineers perform critical tests to identify flaws that could otherwise cause failures in planes, reactors, trains, pipelines and other systems, helping to assure their reliable and cost-effective operation while preserving future functionality.

2.  Non-destructive testing (NDT) is a wide group of
analysis techniques used in science and industry to
evaluate the properties of a material, component
surface & subsurface without causing damage or effect
to their future performance or properties.
 Non-destructive testing is used to detect abnormalities
in physical, chemical or electrical characteristics.

3.  NDT provides an edge over conventional methods as it
is a fast, cheap and easy process.
 In 1930s, non destructive testing, where it had been
heard of at all, was generally considered an evil. Later
it became a necessary evil. For a number of years now
NDT has been a necessary aid. NDT has saved
uncounted thousands of lives.

4. 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.

5.  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.
 These tests are performed in a manner that does not
affect the future usefulness of the object or material.
