GB/T 43297 - 2023 is a standard for evaluating the optical aging performance of plastic polymers, using Fourier infrared Light spectrum and ultraviolet/visible Light spectrum methods. It strictly regulates the preparation process of test samples to ensure that the samples meet the requirements. Clearly define the operation details of the two types of Light spectrum equipment, and accurately determine the aging degree by comparing the characteristics of Light spectrum before and after plastic polymer light aging. According to this standard, it can provide optical aging data for outdoor plastic products, help material research and development, estimate product life, and promote technological progress in the plastics industry.
