Light fastness tests are performed as described in ISO 2135 and ASTM G155. HAI can therefore offer lightfastness tests according to ISO 7599 and MIL-PRF-8625, type I and II, class 2 and Qualanod.
The lightfastness test is a standardized method for assessing the ability of a material or object to resist color changes or discoloration when exposed to lighting over time.
The test typically involves exposing the sample material or object to a specified amount of light for a specified period of time and then assessing any color changes or discoloration using a standardized scale or color swatches.
