Alternate the measurement side for double sided textured sheet
Machine direction (MD) and cross machine direction (XMD) average va ues should be on the basis of 5 test specimens each direction
• Break elongation is calculated using a gage length of 2 0 in at 2 0 in /mm
Other methods such as D 1603 (tube furnace) or D 6370 (TGA) are acceptable if an appropriate correlation to D 4218 (muffle furnace) can be established
Carbon black dispersion (only near spherical agglomerates) for 10 different views
• 9 in Categories 1 or 2 and 1 in Category 3
The manufacturer has the option to select either one of the OIT methods listed to evaluate the antioxidant content in the geomembrane
It is also recommended to evaluate samples at 30 and 60 days to compare with the 90 day response
The condition of the test should be 20 hr UV cycle at 75°C followed by 4 hr condensation at 60°C
Not recommended since the high temperature of the Std-OIT test produces an unrealistic result for some of the antioxidants m the UV exposed samples
UV resistance is based on percent retained value regardless of the original HP-OIT value
