Lowest individual of 10 values
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
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.

Carbon black dispersion for 10 different views:
* minimum 9 of 10 in Categories 1 or 2
* all 10 in Categories 1, 2, or 3
The yield stress used to calculate the applied load for the
SP-NCTL test should be the manufacturer's mean value
via MQC testing.
The manufacturer has the option to select either one of the OIT
methods listed to evaluate the antioxidant content in the geomembrane.
It also is recommended to evaluate samples at 30 and 60 	
days to compare with the 90 day response.

[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.
