Which procedure is used to verify the extent of a defect after a visual identification?

• A. Physical
• B. Visual
• C. Acoustic
• D. Thermal

Answer: (A)

Verifying the extent of a defect after a visual identification requires a physical measurement. Visual inspection can reveal that a defect is present, but only a physical method—using calibrated tools to measure the crack length, depth, width, or pit size—provides precise, quantitative dimensions of the defect. This direct measurement establishes the true size and boundaries, which are essential for assessing severity and planning repairs. Other methods like acoustic or thermal can indicate anomalies or subsurface features, but they don’t reliably deliver exact dimensions of the defect, so they’re not as definitive for determining extent.
