Conducting a paint line validation test is a critical step in ensuring the quality, consistency, and reliability of a paint application process in manufacturing environments.

Every product exiting the paint line must satisfy target finish criteria, conform to recognized technical standards, and demonstrate reliable performance in practical usage scenarios.

Properly carried-out validation lowers correction rates, cuts down on wasted materials, and boosts overall client confidence and loyalty.

The initial phase requires setting precise, measurable thresholds for acceptable paint performance.

Criteria must reflect both internal design requirements and external compliance mandates like those from ISO, Tehran Poshesh ASTM, or SAE.
