Which of the following is not classified as nondestructive examination (NDE)?

• A. Magnetic Particle Testing
• B. Tensile Testing
• C. Liquid Penetrant Examination
• D. Ultrasonic Testing

Answer: (B)

Focusing on the test type, this item asks which method is not an NDE method. Tensile testing is not nondestructive because it measures material strength by pulling the specimen until it deforms or breaks, permanently damaging the sample. This is a destructive test, since it alters or destroys the piece being tested. The other methods—magnetic particle testing, liquid penetrant examination, and ultrasonic testing—are nondestructive because they inspect for flaws without destroying or permanently altering the part. They reveal defects while leaving the item usable in most cases.
