16 lis 2023 · The ASTM G154 test method involves subjecting material specimens to fluorescent UV radiation under controlled conditions, replicating sunlight exposure. The test is typically performed using one of two types of apparatus, namely Type A or Type B, depending on the desired spectrum of UV radiation.
ASTM G154 is an American standard for measuring accelerated weather testing. In technical terms, it sets the standard for operating fluorescent light instruments to test the performance of non-metallic materials when exposed to weathering conditions.
1 sty 2023 · Standard Practice for Operating Fluorescent Ultraviolet (UV) Lamp Apparatus for Exposure of Materials. 1.1 This practice is limited to the basic principles for operating a fluorescent UV lamp and water apparatus; on its own, it does not deliver a specific result. 1.2 It is intended to be used in... ASTM G154-16.
The ASTM G154 and G155 tests evaluate the resistance of a nonmetallic material to simulated sunlight and moisture exposure. When rays of sunlight—particularly UV rays—bombard a surface, they degrade smaller pigment particles, changing the surface color and creating a chalky effect.
