ASTM E 1495 - 97. Standard Guide for Acousto-Ultrasonic Assessment of Composites, Laminates, and Bonded Joints

American Society for Testing and Materials (ASTM). 1997, 9 pages.
This guide explains the rationale and basic technology for the acousto-ultrasonic (AU) method. Guidelines are given for nondestructive evaluation (NDE) of flaws and physical characteristics that influence the mechanical properties and relative strength of composite structures (for example,
filament-wound pressure vessels), adhesive bonds (for example, joints between metal plates), and interlaminar and fiber/matrix bonds in man-made composites and natural composites
(for example, wood products).
