Abstract
This paper discusses the effect of varying UV intensity on weathering degradation rates of materials. The effects of increasing intensities of solar UV on materials obeying strict reciprocity and materials deviating from strict reciprocity are considered. A second new high-intensity natural UV weathering device is introduced based on ASTM G90. The paper presents data from two materials degrading under different intensities of UV and compares natural weathering with data obtained at increasing levels of UV intensity with implications on SLP calculations.
