27 sty 2023 · ASTM G154-23. Standard Practice for Operating Fluorescent Ultraviolet (UV) Lamp Apparatus for Exposure of Materials. Significance and Use. 5.1 The use of this apparatus is intended to induce property changes consistent with the end use conditions, including the effects of the UV portion of sunlight, moisture, and heat.
ASTM G154 is an accelerated UV ageing test using Specific Fluorescent lights to simulate the impact of sun exposure on paints, coatings and polymers.
Designation: G154 − 23 Standard Practice for Operating Fluorescent Ultraviolet (UV) Lamp Apparatus for Exposure of Materials1 This standard is issued under the fixed designation G154; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
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.
