Section 89 Non-destructive testing

Non-destructive testing (NDT) is a method of testing materials and components that does not damage or destroy the test sample. NDT tests include measuring for flaws, thickness, material condition, corrosion, bulk conductivity, residual stress, alloy type, hardness, microstructure heat treatment verification and modulus.

NDT methods include the use of :

(a) eddy currents;
(b) ultrasound transducers;
(c) acoustic emission;
(d) magnetism, including induction or Barkhausen;
(e) a beta gauge;
(f) optical techniques such as a shearograph or holograph;
(g) radiography e.g. x-ray imaging.
