4 method overview

When using the ultrasonic pulse echo method to measure the thickness, the thickness value (T) is the product of the speed of sound and the half of the travel time of the ultrasound in the material, see Formula 1). T = V × t/2 (1) In the formula. T --- material thickness, in millimeters (mm); V --- material velocity of sound, in millimeters per second (mm/s); t --- ultrasonic transmission back and forth in the material time, in seconds (s).

5 test equipment and equipment

5.1 ultrasonic thickness gauge 5.1.1 Ultrasonic thickness gauge should have "sound speed setting" and "zero correction" function, can be applied to non-metallic materials testing. NOTE Some sonic guns have the same name for Sound Velocity Settings as Material Selection or Sound Velocity Correction. 5.1.2 ultrasonic thickness gauge accuracy should not be less than 0.01mm. 5.1.3 ultrasonic thickness probe, cable should be matched. 5.1.4 ultrasonic thickness gauge should be used directly contact single crystal straight probe. ......
