[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.
