Assessing Remaining Service Life of HDPE Geomembranes (How Long Will My liner Last?)
ExcelPlas has developed Protocol for Determining the Remaining Service Life of an Already Exposed HDPE Geomembrane Liner
The 5 step protocol is based on lab testing to measure the following:
I.  The oxidative induction time (OIT) profiling to assess whether or not oxidation protection is still afforded by the additives.
II.  Measure the carbonyl index (CI) to assess extent of any polymer oxidation that has occurred.
III. Determine the critical CI at which stress cracking (SC) is initiated.
iV. Measure stress cracking resistance (SCR) to determine the time until SC is initiated.
V.  Measure the depth of micro cracking on 180 degree bent coupons by Scanning Electron Microscopy
