ASTM E494 – Standard Practice for Measuring Ultrasonic Velocity in Materials by Comparative Pulse-Echo Method

1.1”This practice covers a test procedure for measuring ultrasonic velocities in materials with conventional ultrasonic pulse echo flaw detection equipment in which results are displayed in an A-scan display. This practice describes a method whereby unknown ultrasonic velocities in a material sample are determined by comparative measurements using a reference material whose ultrasonic velocities are accurately known.
