Proposed revision to NSF/ANSI 53: Drinking Water Treatment Units – Health Effects (53i140r1)
The proposed revision will correct two typographical errors and a consistency oversight. It will:
- Revise Section 7.4.3.5.2.3.1, Solution preparation to change two instances of Pb(NO3) to Pb(NO3)2
- Update Table 7.13, Mercury reduction requirements to add a column for the individual influent sample point limit, for consistency with Table 7.11 |
