ASTM G154 is a standard practice for operating fluorescent UV lamp apparatus to assess the resistance of non-metallic materials to UV and accelerated aging. Learn about the uses, benefits, parameters, and alternatives of this method, and how Micom can help you with customized services.
This standard describes the basic principles and procedures for operating a fluorescent UV lamp and water apparatus to expose materials to simulated weathering conditions. It is intended to be used in conjunction with other methods that define specific exposure conditions and evaluate material properties.
ASTM G154 is an American standard for measuring how non-metallic materials perform in harsh weather conditions using fluorescent lights. Learn what it is, when to use it, and what to look out for when conducting the test.
1 sty 2023 · This standard describes the basic principles and procedures for operating a fluorescent UV lamp and water apparatus to reproduce the weathering effects of sunlight and moisture on materials. It is intended to be used in conjunction with other methods or specifications that define specific exposure conditions and evaluate material properties.
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.
ASTM-G154 covers the basic principles and operating procedures for using fluorescent UV light and water apparatus to reproduce weathering effects on nonmetallic materials. It does not specify the exposure conditions best suited for the material to be tested, but provides guidance and references for specimen preparation and evaluation.
