| (1) Test methods modified to 20 in./min. for unreinforced and 12 in./min. for reinforced. | ||
| (2) Calculation based on a 2.0 in. gage length | ||
| (3) Using 1/ in. mandrel for 4-hours | ||
| (4) Applicable only to black geomembranes. Also D1603 is an acceptable
method to determine carbon black content. |
||
| (5) Not recommended since high temperature of the Std-OIT test procedures an unrealistic result for some antioxidants used in fPP formulations. | ||
| (6) It is also recommended to evaluate samples at 15 days to compare with the 30 day response. | ||
| (7) The condition of the test should be 20 hr. UV cycle at 75ºC followed by 4 hr. condensation at 60ºC.` | ||
