Test Method Title
Accelerated Weathering of Geomembranes Using a Fluorescent UVA Device
GRI GM 11
Percent retained OIT, breaking strength, breaking elongation and melt index
Description of Test
Geomembrane specimens are alternately exposed to ultraviolet light and to condensation for a number of pre-determined cycles. Specimens are periodically removed from exposure and tested for OIT, breaking strength, breaking elongation and melt index. A determination is made as to the percent retained of each property evaluated.
