WebOct 29, 2024 · A dye penetration test is a type of nondestructive evaluation used to detect surface flaws on a material. The dye penetration test uses a liquid called a penetrant that flows into any flaws on the material's surface to increase the visibility of the surface discontinuities, making them easier to detect and measure. Advertisement. WebDye Liquid Test (DPT) is one of one simple and oldest Non-Destructive Inspection methods. Also, known how the Solid penetration test, the Dye penetrant test is widely previously to detect surface discontinuities like cracks, fractures, porosity, grinding defects, incomplete meld, and flaws include joints.
