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

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.

7. 2L Sample Mandate for POEs Tab 8: DWA-61-2013-11 Proposed revision:

8. 2L Sample Mandate for POEs Tab 8: DWA-61-2013-11 Proposed revision: Note: Additional units are to be exposed if additional extraction water is needed to complete analysis…
