Also an electrically conductive layer can be added upon request. [1] HDPE = High density polyethylene = Coextruded CX T = Textured S = Smooth [2] Lowest individual of 10 values [3] Machine direction (MD) and cross machine direction (XD) average values should be on the basis of 5 test specimens each direction * Yield elongation calculated with a gage length of 33mm * Break elongation calculated with a gage length of 50mm [4] Other methods such as D 4218 (muffle furnace) or microwave methods are acceptable if an appropriate correlation to D 1603 (tube furnace) can be established. [5] Carbon black dispersion for 10 different views: * minimum 9 of 10 in Categories 1 or 2 * all 10 in Categories 1, 2, or 3 [6] The yield stress used to calculate the applied load for the SP-NCTL test should be the manufacturer's mean value via MQC testing. [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. « Geosynthetics recommends you contact the manufacturers before making any specifying/purchasing decisions » GeosyntheticsMagazine.com 57 [9] 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.
