[7] The manufacturer has the option to select either one of the OIT methods listed to evaluate the antioxidant content in the geomembrane. [8] It also is recommended to evaluate samples at 30 and 60 days to compare with the 90 day response. The condition of the test should be 20 hr. UV cycle at 75 C followed by 4 hr. condensation at 60 C. [10] UV resistance is based on percent retained value regardless of the original HP-OIT value.
