Non-destructive Testing: Important Terminology
Updated: Feb 27, 2020
There are many different non-destructive testing techniques recognized by the American Society for Non-destructive Testing (ASNT) including Acoustic Emission Testing (AE), Electromagnetic Testing (ET), Ground Penetrating Radar (GPR), Laser Testing Methods, Leak Testing (LT), Liquid Penetrant Testing (PT), M
agnetic Flux Leakage (MFL), Magnetic Particle Testing (MT), Microwave Technology, Neutron Radiography Testing, Radiographic Testing, Thermal/Infrared Testing, Ultrasonic Testing, Vibration Testing, and Visual Testing. It is interesting to note, however, that most of these techniques process non-destructive testing information in the same sequence to determine the final conclusion on an indication or to answer the existential question; is it a defect or is it not a defect?
