Scope: This standard specifies the method for measuring the velocity of ultrasound in materials with Type A pulse-echo ultrasonic flaw detection equipment. This standard applies to solid materials with a thickness greater than or equal to 5mm, and the parallelism between the two surfaces perpendicular to the ultrasonic energy propagation direction is between ±3°, and the surface roughness coupled with the ultrasonic probe is better than 3.2μm.
