Abstract
This is part of a major research program to identify a testing protocol that will enable us to accurately predict the field performance of roofing membranes. Twelve commercially available roofing membranes were selected for this study. Samples of each membrane were exposed on racks in three U.S. locations, and were expected to return the samples to the laboratory after two, four and six years of exposure. The following protocols were tested to see which are most effective in predicting performance: comparing the combination of original data and chanage due to heat aging samples for 28 days at 70C. This work is reported in this preliminary report. Comparing the combination of original data and changtes dues to a condensing humidity and ultra violet environment.
