GB/T 23983-2009 "Determination of wood coatings yellowing resistance" standard specifies the determination method of wood coatings yellowing resistance. Artificial climate aging tests are carried out on films by using fluorescent ultraviolet aging equipment to simulate the effect of ultraviolet radiation on Coatings. The standard applies to the yellowing test of various wood coatings. In the test, the film is irradiated with ultraviolet rays for a certain period of time, and the performance is compared with the unexposed film to evaluate the yellowing resistance of Coatings. The standard details equipment requirements, sampling, panel handling, procedures, and presentation of results to ensure test accuracy and conformity.
