The ASTM D5146-19 standard guide details testing procedures for solvent-based architectural coatings for exterior and interior surfaces. The guide includes inspection of liquid Coating properties (e.g. density, flash point, Stability, etc.), coating application and film formation characteristics (e.g. brushing, roller coating, la me plating performance, etc.), Dry-Film Appearance (e.g. Color, Gloss, hiding power, etc.), and Dry-Film performance (e.g. abrasion resistance, adhesion, chemical resistance, etc.). In addition, chemical analysis of coatings is also covered. The guideline aims to ensure that the performance of coatings in practical applications is as expected, providing comprehensive performance evaluation criteria.
