The proposed revision is to specify methanol as the acceptable solvent for organic chemical and VOC reduction testing, and adds individual sample point limits for the chloroform surrogate test for VOC reduction under NSF/ANSI 53. The revision shall also be reflected under the appropriate sections of NSF/ANSI 58.
Revision 2 addresses the comment received from the revision 1 ballot that methanol’s use as a solvent is a requirement and should not be stated as a note. This two-week adjudication ballot also addresses any unresolved negative comments that were received suggesting that the tolerance for individual influent sample point limits for the chloroform surrogate test be restricted to ± 20% instead of the current proposed ± 30%.
This ballot allows voters the opportunity to change or reaffirm their vote based on the content of the comments contained herein. |
