GB/T 16422.3-2022 is a laboratory exposure test standard for plastics under fluorescent ultraviolet light sources. It specifies the parameters of fluorescent UV Lamp equipment, such as Wavelength range, irradiation intensity and other requirements. There are detailed regulations on the preparation of plastic samples, from material selection to Sample size and shape. In the test process, the sample Installation method is standardized, and the exposure time, cycle period, and environmental conditions such as temperature and Humidity are strictly controlled. Using fluorescent UV Lamp to simulate outdoor ultraviolet radiation and accelerate plastic aging, in order to accurately evaluate the weathering performance of plastics, provide key technical support for the mass control and research and development of plastic products, and help the industry improve product quality.
