Description / Abstract:
Purpose
This specification covers procedures for ultrasonic inspection,
by pulse-echo procedures, of flat, rectangular, round, cylindrical,
and contoured products having a thickness or cross-sectional
dimension greater than 0.50 inch (12.7 mm), using either contact or
immersion methods, and using the longitudinal-wave or shear-wave
modes or combinations of the two, as necessary. This specification
may apply to testing finished machined parts provided the parts can
meet the basic testability requirements, such as size, contour,
metallurgical structure, and thickness.
Parts with section thickness both over 0.50 inch (12.7 mm) and
0.5 inch (12.7 mm) and under may be tested using this procedure and
AMS2632, as applicable.
Application
This procedure has been used typically for locating and defining
internal defects such as cracks, voids, laminations, and other
structural discontinuities which may or may not be exposed to the
surface, but usage is not limited to such applications.
