Inspect paint adhesion on the grid.

Acceptance Criteria: Paint peel-off < 5% (≥4B rating).

Environment: Room temperature

Colour Difference Inspection

Color Difference (ΔE) & Components

ΔE = Total color difference (magnitude).

ΔL = Lightness: + (whiter), − (darker).

Δa = Red/Green: + (redder), − (greener).

Δb = Yellow/Blue: + (yellower), − (bluer).

Tolerance Levels (ΔE)

0–0.25 = Ideal match (very small/none).

0.25–0.5 = Tiny (acceptable).

0.5–1.0 = Small-medium (acceptable in some cases).

1.0–2.0 = Medium (acceptable in some applications).

2.0–4.0 = Noticeable (acceptable in certain cases).

>4.0 = Very large (unacceptable).
