ISO 4628-3 is a standard titled "Paints and varnishes — Evaluation of degradation of coatings — Designation of intensity of existing defects and damage — Part 3: Assessment of degree of blistering".

ISO 4628-3 provides a methodical approach for assessing the degree of blistering on painted or varnished surfaces. This standard is crucial for maintaining the quality and performance of coatings by allowing manufacturers, quality inspectors, and engineers to evaluate coating defects systematically. By following this standard, industries can ensure that coatings meet durability and aesthetic requirements, and address blistering issues before they lead to more significant problems.
