Dye Penetration Test
The Dye Penetration Test is a non-destructive test used to detect surface cracks and defects in materials such as metal, ceramics, and plastics. The test involves applying a liquid dye to the surface of the material and allowing it to penetrate any surface cracks or defects. After a specified period, the excess dye is removed, and a developer is applied to draw out the dye that has penetrated the cracks. The resulting pattern reveals any defects or cracks in the material’s surface, which can then be repaired or addressed as necessary. In construction, the Dye Penetration Test is often used to evaluate the integrity of welds, joints, and other components that are critical for the structural integrity of the building or infrastructure.
