: It is not intended for the corrosion testing of bare metals (refer to ASTM G50 for those procedures).

Predicting how a material will degrade over several years is complex due to year-to-year climatological variations. astm g7 pdf

The standard details specific configurations to ensure tests are repeatable and results are comparable across different laboratories. : It is not intended for the corrosion

: Specimens are mounted on a black-painted aluminum box to simulate the higher temperatures experienced by materials like automotive coatings. astm g7 pdf

: Testing is typically performed on racks tilted at specific angles from the horizontal (commonly 5° or 45° ) and facing the equator to maximize solar radiation.

: Specimens are attached to a solid substrate, like plywood, which can increase surface temperature and simulate certain end-use conditions.
