The GB/T 8427-2019 standard provides a test method for the color fastness of Spinning & weaving products to artificial light, using Xenon-arc lamps for simulated sunlight exposure. The standard is used to evaluate the Color change of Spinning & weaving products under long-term lighting conditions to ensure that they are not easy to fading in practical applications. The test includes the time and conditions of exposure to Xenon-arc lamps to detect the color fastness of Spinning & weaving products. This standard is of great significance for the quality control and product development of Spinning & weaving products, ensuring the Stability and durability of their colors.
