This standard covers factory-coated bolted steel tanks for water storage and is based on the accumulated knowledge and experience o

47、f manufacturers of bolted steel tanks. * I.B. History. The first version of this standard was prepared in cooperation with the Bolted Tank Manufacturers Association and was issued in 1980. It was prepared in response to the increasing use of bolted tanks for water storage. AWWA D103-80 was later upd

48、ated and approved as AWWA D103-87 on June 14, 1987. The third edition of ANSI/AWWA D103-97 was approved by the AWWA Board of Directors on June 15, 1997. The fourth and current edition of ANSI/AWWA D103 was approved on Jan. 25, 2009. I.C. Acceptance. In May 1985, the US Environmental Protection Agenc

49、y (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 all direct and indirect drinking water additives. Other members of the original consortium included the American Water Works Association Research Foundation (AwwaRF) and the Conference of State Health and Environmental Managers (COSHEM). The American Water Works Association (AWWA) and the Association of State Drinking Water Administrators (ASDWA) joined later. In the United State
