GB/T 21353-2008 "Test Method for Algal Resistance of Paint Films" specifies the test methods and evaluation criteria for the algal resistance of outdoor architectural paint films. It conducts accelerated tests by simulating the temperature, humidity, and light conditions conducive to natural algal growth, and observes the extent of algal growth on the paint film surface. The detection requires instruments such as biosafety cabinets, autoclaves, constant temperature incubators, and microscopes, providing a technical basis for grading the algal resistance of coatings and guiding their application selection.
