Zarghamee, Simpson Gumpertz and (2) the embedded-cylinder type, with a core composed of a steelcylinder encased in concrete and subsequently wire-wrapped on the exterior concretesurface and coated with cement mortar. The lined-cylinder type, which was first usedin the U

17、nited States in 1942, is provided in sizes from 16 in. (410 mm) to 60 in.(1,520 mm). The embedded-cylinder type, which was developed later and firstinstalled in 1953, is most commonly manufactured in sizes 48 in. (1,220 mm) andlarger.Both types are designed for the specific combination of internal p

18、ressure andexternal load required for the project in accordance with the procedures outlined inANSI/AWWA C304, Standard for Design of Prestressed Concrete Cylinder Pipe.Prestressed concrete steel-cylinder pipe is used for transmission mains, distribu-tion feeder mains, pressure siphons (including ri

19、ver crossings), penstocks, industrialpressure lines, water intake lines, and other applications.In the manufacture of lined-cylinder pipe, the first step is to fabricate andhydrostatically test the steel cylinder with joint rings attached. The cylinder is thenlined with concrete to form the core. Th

20、e concrete is placed either centrifugally, byvertical casting, or by a radial compaction method. The concrete lining is cured andhigh-tensile wire is wrapped around the core directly on the steel cylinder. For aselected wire size, the tension and spacing of the wire are controlled to produce apredet

21、ermined residual compression in the core to meet design requirements. Thewrapped core is then covered with a dense premixed mortar coating applied by amechanical impact method.In the manufacture of embedded-cylinder pipe, the cylinder and joint rings areconstructed and tested in the same manner as l

22、ined-cylinder pipe. The cylinder isencased in concrete by vertical casting and mechanical vibration to constitute thecore. After curing, the wire reinforcement is wound under tension in one or morelayers around the outside of the concrete core containing the cylinder, instead ofCopyright American Wa

The second editionwas approved as tentative June 17, 1955, and made standard June 26, 1958.Substantial changes, including the addition of combi

25、ned loading procedures, wereincluded in the third edition, which was made standard Jan. 27, 1964. The standardwas revised again on Jan. 31, 1972; June 24, 1979; Jan. 30, 1984; June 22, 1992; andJan. 24, 1999. This edition was approved by the AWWA Board of Directors onJan. 21, 2007.I.C.

26、n May 1985, the US Environmental Protection Agency(USEPA) entered into a cooperative agreement with a consortium led by NSFInternational (NSF) to develop voluntary third-party consensus standards and acertification program for direct and indirect drinking water additives. Othermembers of the origina

27、l consortium included the American Water Works AssociationResearch Foundation (AwwaRF) and the Conference of State Health and Environ-mental Managers (COSHEM). The American Water Works Association (AWWA)and the Association of State Drinking Water Administrators (ASDWA) joined later. In the US, autho

28、rity to regulate products for use in, or in contact with, drinkingwater rests with individual states.*Local agencies may choose to impose requirementsmore stringent than those required by the state. To evaluate the health effects ofproducts and drinking water additives from such products, state and

29、local agenciesmay use various references, including1. An advisory program formerly administered by USEPA, Office of DrinkingWater, discontinued on Apr. 7, 1990.2. Specific policies of the state or local agency.3. Two standards developed under the direction of NSF, NSF/ANSI60,*Persons outside the Uni

32、 other standards considered appropriate by the state or localagency.Various certification organizations may be involved in certifying products inaccordance with NSF/ANSI 61. Individual states or local agencies have authority toaccept or accredit certification organizations within their jurisdiction.

33、 Accreditationof certification organizations may vary from jurisdiction to jurisdiction.Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 61does not stipulate a maximum allowable level (MAL) of a contaminant for substancesnot regulated by a USEPA final maximum contaminant level (MC

34、L). The MALs ofan unspecified list of “unregulated contaminants” are based on toxicity testingguidelines (noncarcinogens) and risk characterization methodology (carcinogens).Use of Annex A procedures may not always be identical, depending on the certifier.ANSI/AWWA C301 does not address additives re

35、quirements. Thus, users of thisstandard should consult the appropriate state, local, or provincial agency havingjurisdiction in order to1. Determine additives requirements including applicable standards.2. Determine the status of certifications by parties offering to certify productsfor contact with

36、, or treatment of, drinking water.3. Determine current information on product certification.II. Special Issues. This standard has no applicable information for thissection.III. Use of This Standard. It is the responsibility of the user of an AWWAstandard to determine that the products described in t
