ASTM D 4587-2001 "Fluorescence ultraviolet, condensation exposure test for paints and related coatings", specifies the fluorescent ultraviolet and condensation exposure test methods for paints and related coatings. The standard specifies the requirements of test equipment, sample prepative specifications, and details the fluorescent ultraviolet light source, condensation condition setting and test cycle. By simulating the accelerated aging environment, observe and evaluate the changes in coating Appearance and performance, and provide a unified technical standard and testing process for quickly judging paints and coating aging performance.
