Proposed revision to NSF/ANSI 53: Drinking Water Treatment Units – Health Effects (53i125r2) and NSF/ANSI 58: Reverse Osmosis Drinking Water Treatment Systems (58i90r2)
The proposed revision will add additional PFAS compounds to the chemical reduction claims under NSF/ANSI 53 and NSF/ANSI 58. Revision 2 addresses two comments received during the r1 ballots (7/7/20), which requested successful completion of validation testing. The testing has been completed and values updated accordingly. |
