  1. Tab 8: DWA-61-2013-11 Elimination of 2L Minimum SamplePOE systems and components Peter Greiner, NSF International DWAJC Meeting - December, 2013

  2. 2L Sample Mandate for POEs Tab 8: DWA-61-2013-11 • Originated from material safety test in DWTU standards

  3. 2L Sample Mandate for POEs Tab 8: DWA-61-2013-11 • Originated from material safety test in DWTU standards • DWTU standards only use 1 test water chemistry

  4. 2L Sample Mandate for POEs Tab 8: DWA-61-2013-11 • Originated from material safety test in DWTU standards • DWTU standards only use 1 test water chemistry • POEs now evaluated under NSF/ANSI 61 and are evaluated to three different waters (pH 5, 10, and 8)

  5. 2L Sample Mandate for POEs Tab 8: DWA-61-2013-10 • Originated from material safety test in DWTU standards • DWTU standards only use 1 test water chemistry • POEs now evaluated under NSF/ANSI 61 and are evaluated to three different waters (pH 5, pH 10, and pH 8) • Means a mandate of three times as many samples under NSF/ANSI 61 which may not be needed for analytical reasons.

  6. 2L Sample Mandate for POEs Tab 8: DWA-61-2013-11 • Originated from material safety test in DWTU standards • DWTU standards only use 1 test water chemistry • POEs now evaluated under NSF/ANSI 61 and are evaluated to three different waters (pH 5, pH 10, and pH 8) • Means a mandate of three times as many samples under NSF/ANSI 61 which may not be needed for analytical reasons. • Recommend removal of mandated 2L minimum.
