Scope

Scope: This standard specifies the methodological guidelines for measuring material thickness using the non-contact electromagnetic ultrasonic pulse echo method under conditions where the temperature does not exceed 650°C. This standard applies to the measurement of the thickness of conductive or ferromagnetic materials where ultrasonic waves can propagate internally at a constant speed and reflect off the backside for detection and resolution.
