Which VT indications are typically rejected?

• A. Minor surface texture variations.
• B. Visible cracks, deep gouges, severe corrosion, large/through-surface delaminations, and coating damage that reveals substrate defects.
• C. Slight color variation only.
• D. Small pinholes.

Answer: (A)

Visual testing looks for surface flaws that could affect the part’s integrity. Indications that lead to rejection are the serious defects: cracks that can grow, deep gouges, severe corrosion, large or through-surface delaminations, and coating damage that reveals substrate defects. These signal actual damage or compromised structure, so they’re disqualified under most acceptance criteria. In contrast, minor surface texture variations, slight color differences, or a few small pinholes are typically within acceptable limits and not automatically rejected unless a specific standard says otherwise. So, the indications that are typically rejected are the larger, structural-type defects rather than minor cosmetic imperfections.
