The data below was collected using representative samples of Royal Wood® product with the white co-extruded ASA acrylic cap.
Type of Test: Accelerated Weathering Test
Test Apparatus: Xenon Arc Light and Moisture Equipment
Test Method: ASTM G155-98
Conclusion
After 6,000 hours of exposure, the total color shift (ΔE) is only .5. In general, the color shift has to be higher than a ΔE change of 3.0 to be visually observed. With many colors, it will be closer to ΔE of 5.0 to be visually observed.
