The ASTM D5031M-2018 standard is used to evaluate the light, heat and moisture resistance performance of Coatings in a closed carbon arc environment. This method detects the physical and Optical Property changes of Coatings under extreme environment conditions by simulating the effects of light, heat and water on Coatings. This practice is particularly suitable for studying the deterioration process of Coatings under actual use conditions, but not for simulating the deterioration of local weather phenomena. Results may vary depending on operating conditions. Therefore, specific test conditions need to be detailed to ensure the Reliability of the results. This method requires a strict and consistent equipment configuration for comparison between laboratories to guarantee the reproducibility and accuracy of the results.
