Note:
1
Machine Direction (MD) and Transverse Direction (TD) average
values are on the basis of 5 specimens each direction.
2
The yield stress used to calculate the applied load for the
SP-NCTL test should be the mean value via MQC testing.
3
Carbon Black Dispersion for 10 different views: 9 in
Categories 1 and 2 with 1 allowed in Category 3.
4
The condition of the test should be 20 hr. UV cycle at 75°C
followed by 4 hr. condensation at 60°C.
5
UV resistance is based on percent retained value regardless
of the original HP-OIT value.
