Definition

A set of inspection and evaluation techniques (e.g., ultrasonic, radiographic/X‑ray, magnetic particle, eddy current, dye‑penetrant, visual, leak testing) used to detect, characterize, and sometimes quantify discontinuities, defects, or material properties in components and structures without impairing their future usefulness.
