The AATCC 16.3-0 standard is a test method for the color fastness of Spinning & weaving materials to light, using a Xenon-arc Light source to simulate sunlight exposure conditions for accelerated aging evaluation. The standard uses xenon discharge lamps as the radiation source, covering a range from ultraviolet to visible Light spectrum and infrared. The test is designed to measure the colour fastness of materials under sunlight exposure, and is particularly suitable for applications that require resistance to prolonged sun exposure, such as vehicle interiors. The standard ensures color Stability and durability of materials during use and is an important tool for evaluating the mass and performance of Spinning & weaving products.
