The ASTM D3424-2011 standard specifies methods for evaluating the relative colour fastness and weathering resistance of printings to sunlight. The standard covers a variety of test procedures, including daylight behind window panes, outdoor efflorescences, daylight and weathering conditions simulated by Xenon-arc devices, and indoor fluorescent lamp simulations. These accelerated test methods help to quickly assess the light fastness or weathering resistance of printings under different Light sources, facilitating specification acceptance and quality control by producers and users. The standard emphasizes that tests performed with Xenon-arc lamps can more accurately simulate natural light, and that test results are critical to judging the actual use performance of printings.
