nondestructive testing

[¦nän·di′strək·div ′test·iŋ]
(engineering)
A technique for revealing flaws and defects in a material or device without damaging or destroying the test sample; includes use of x-rays, ultrasonics, radiography, and magnetic flux.

Nondestructive testing

Testing that does not destroy the object being tested. Techniques include the use of strain gauges, x-rays, and ultrasound.

nondestructive testing (NDT)

Techniques of testing aircraft parts and components without altering or destroying physical or material properties or the integrity of the part. It is used to detect cracks and manufacturing defects. Some of the methods include X-ray, eddy current, magnetic, and dye penetrant testing. See eddy current testing, magnetic inspection, and dye penetrant testing.
