1. Machine direction (MD) and cross machine direction (XMD) average values should be on the basis of 5 test specimens each
    direction. Yield elongation is calculated using a gauge length of 33 mm; Break elongation is calculated using a gauge
    length of 50 mm.
2.
The yield stress used to calculate the applied load for the SP-NCTL test should be the mean value via MQC testing.
3.
Other methods such as ASTM D 4218 or microwave methods are acceptable if an appropriate correlation can be established.
4.
Carbon black dispersion for 10 different views: 9 in Categories 1 and 2 with one allowed in category 3.
5.
The condition of the test should be 20 hr. UV cycle at 75°C followed by 4 hr. condensation 60°C.
6.
UV resistance is based on percent retained value regardless of the original HP-OIT value.
