| 7<\/td>\n | Foreword I.\tIntroduction. I.A.\tBackground.\u2003A fabricated aluminum slide gate is a vertically sliding gate, fabricated from rolled or extruded aluminum shapes, with ultra-high-molecular-weight polyethylene (UHMW-PE) seating faces and seals or UHMW-PE seating faces and resilient rubb <\/td>\n<\/tr>\n | ||||||
| 8<\/td>\n | I.B.\tHistory.\u2003The original AWWA standard for slide gates (then referred to as sluice gates) was approved as tentative on June 26, 1941, and described cast-iron gates. The tentative standard was revised and approved on June 4, 1967, as AWWA C501. Subsequen I.C.\tAcceptance.\u2003In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct <\/td>\n<\/tr>\n | ||||||
