Non-destructive testing (NDT) is a group of testing technologies used in industry to evaluate the properties of a material, component, structure or system without causing damages. NDT includes radiography testing (RT), ultrasonic testing (UT), as well as acoustic emission (AE). Vibration testing is another prominent monitoring and analysis tool used across many industries.
