Page 2 Filename: Agru Oven and QUV Exposure Testing 103117.pdf The following oven aging and UV exposure test methods were conducted in accordance with the GRI- GM13 (HDPE)and GRI-GM17 (LLDPE)requirements: Test Name Exposure Conditions Test Method Oven Aging 90 days in an oven at 85 °C ASTM D5721 UV 1600 UV irradiance hours. Cycle: 20 hours UVA-340 at 75 °C ASTM D7238 Exposure followed by 4 hours dark with condensation at 60'C. Irradiance was 0.78 W/mz at wavelength 340 nm. Note:This implies a total UV chamber residence time of 1920 hours,e.g., 1600 hours of irradiance and 320 hours of dark/condensation.
