Nondestructive testing is often NDT involves indirect tests related to some other quality or characteristic of material.
differentiated from other measurements or
inspection techniques in that:
Identifying and sorting of material.
What are the functions of NDT? Identifying of material properties.
Ensuring absence of faults or defects that could cause a part to fail.
An important basis for the success of The need to ensure that unexpected flaws of some critical size are not present when
fracture control design procedures is: the component enters service.
If properly used, NDT can assist in fracture Providing an accurate evaluation of the number and type of discontinuities that exist
