NSF experts reviewed studies on PEX tubing and found several deviations in testing methods when compared to the requirements of established industry standards.

Update: NSF reviewed a recent study that provides important new information on testing methods for PEX tubing. See NSF’s review of “Incorporating use phase chemical leaching and water quality testing for life cycle toxicity assessment of cross-linked polyethylene (PEX) piping.”
