General Nondestructive Testing (NDT)

A testing method that examines the surface or internal structure of materials (substrates), products, or structures without damaging or altering the original shape of the object under inspection.

● Nondestructive Testing (NDT): A simple defect detection method to investigate the integrity, performance, and defect condition of the test subject without destroying it.

● Nondestructive Inspection/Examination (NDI/NDE): A technique that not only performs NDT but also evaluates and determines the pass/fail based on the test results and criteria for functionality and integrity.

● Nondestructive Evaluation (NDE): A measurement technique that evaluates the integrity of materials by understanding the loading and environmental conditions, predicting material lifespan using fracture mechanics, and assessing material soundness comprehensively.
