Please review the proposal and return your ballot by the ballot due date of May 17, 2013 via the online workspace (http://standards.nsf.org).
Purpose
This section of NSF/ANSI 46, Field Longevity Verification for Septic Tank Effluent Filters, was developed as a means to evaluate the longevity performance of filtration devices for residential gravity flow septic systems under field conditions. Establishment of a section within an American National Standard ensures a single, comprehensive method for conducting field evaluations, and enables broad acceptance of data to minimize redundant efforts.
