1.1 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.
1.2 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.
1.3 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.strRefField
