Percent retained OIT, breaking strength, breaking elongation and melt index
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.
