GB/T 8427-2008 is the test standard for the colour fastness of Spinning & weaving products against artificial light (Xenon-arc). It specifies in detail the method of testing the colour fastness of Spinning & weaving products by simulating the artificial light environment with Xenon-arc lamps, covering the specifications and parameters of the test equipment, such as the luminous characteristics of Xenon-arc lamps, the irradiation intensity and the Light spectrum distribution. The processing flow of Spinning & weaving products in this environment is clarified, including the key conditions such as light duration and temperature Humidity control, and strict color fastness evaluation rules are formulated. According to this standard test, the Color Stability of Spinning & weaving products under simulated sunlight can be accurately judged, which provides an important basis for mass control of Spinning & weaving products.
