Proposed revisions to:
NSF/ANSI: Residential Wastewater Treatment Systems (40i86r1)
NSF/ANSI: Onsite Residential and Commercial Water Reuse Treatment Systems
(350i89r1)
The proposed revision updates language regarding the oily film and foam test criteria in both NSF/ANSI 40 and NSF/ANSI 350 to align with similar test requirements in the absence of a standard method for measuring oily film and foam. |
