Proposed revision to NSF/ANSI 244: Supplemental Microbiological Water Treatment Systems - Filtration (244i14r1)
The proposed revision corrects misuse of “shall” in informative notes and other terminology that is not acceptable per ANSI requirements. It also updates normative reference language for consistency with other DWTU standards, adds a normative reference, and makes minor corrections to Normative Annex 2 regarding the appropriate procedure and expected concentration range for fr coliphage suspension. |
