New Test for Evaluation of Aqueous Oxidative Resistance of Geomembranes to Oxidative Stress Cracking (OSC)
OSC evaluation of polyolefin geomembranes in accordance with ASTM F2023 (modified) has been undertaken. The ASTM F2023 test method describes the general requirements for evaluating the long-term, chlorinated water, oxidative resistance of polyolefin materials. The test is a circulation loop set up, with controlled pH and chlorine level. The chosen test conditions are 180 degree liner sample dead fold, pH= 6.8 and 4.3ppm chlorine with a so called ORP (Oxidation reduction potential) of above 825mV, one of the harshest test conditions in the geomembrane industry. The aim was to evaluate the chlorine resistance and low LSI water resistance of the HDPE, LLDPE and fPP geomembranes in reference to ASTM F2023. http://www.excelplas.com/
