GB/T 16422.4-2022 focuses on the laboratory exposure test of plastics under an open carbon arc lamp light source. It specifies the equipment requirements for open carbon arc lamps used in the test, and specifies the characteristic parameters of Light sources. For the preparation of plastic samples, detailed instructions are given from material selection, shape to size. During the test, the sample Installation method, exposure time and cycle, and the control of environmental conditions such as temperature and Humidity are standardized. Through this test, the accelerated aging scene of natural light can be simulated, and the light-resistant aging performance of plastics can be accurately evaluated. It provides an important basis for plastic research and development and mass testing, and helps the industry to improve product durability.
