ASTM D5895 Drying & Curing Time Testing for Organic Coating Films
ASTM D5895 is a set of two test methods that are used to evaluate the rate of dry-film formation of organic coatings. The methods are test method A (Straight Line Recorder) and test method B (Circular Recorder), and the results are reported as drying time.

Overview
ASTM D5895 evaluates the drying or curing behavior of organic coatings during film formation by monitoring changes in properties such as viscosity, hardness, or solvent evaporation over time. It provides insight into how coatings transition from liquid to solid film, which is critical for achieving proper performance, adhesion, and durability.
This method is widely used to understand drying mechanisms, optimize curing conditions, and ensure consistent coating quality. It helps manufacturers control application processes, reduce defects such as incomplete curing or poor film formation, and ensure coatings meet required performance standards in various environmental conditions.
