Application Summary AI generated

This standard specifies the pulse-echo testing method using electromagnetic acoustic transducers (EMATs) for non-destructive evaluation of metallic materials. It is applied in industries such as steel manufacturing, pipeline inspection, and rail testing, where contactless ultrasonic detection is needed to identify internal flaws like cracks, laminations, or thickness variations without requiring couplant. The method is particularly useful for high-temperature or moving surfaces where conventional piezoelectric transducers are impractical.
