NDT Test
Nondestructive testing or non-destructive testing (NDT) is a wide group of analysis techniques
used in science and technology industry to evaluate the properties of a material, component or
system without causing damage.

The terms nondestructive examination (NDE), nondestructive inspection (NDI), and
nondestructive evaluation (NDE) are also commonly used to describe this technology. Because
NDT does not permanently alter the article being inspected, it is a highly valuable technique
that can save both money and time in product evaluation, troubleshooting, and research.
Common NDT methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic,
remote visual inspection (RVI), eddy-current testing, and low coherence interferometry.

NDT is commonly used in forensic engineering, mechanical engineering, petroleum
engineering, electrical engineering, civil engineering, systems engineering, aeronautical
engineering, medicine, and art. Innovations in the field of nondestructive testing have had a
profound impact on medical imaging, including on echocardiography, medical
ultrasonography, and digital radiography.
