29、I. Introduction. I.A. Background. Molecularly oriented polyvinyl chloride (PVCO) pressure pipe has been installed in Europe since the early 1970s, and in North America since 1991. The longitudinal molecular structure of polyvinyl chloride (PVC) is reoriented to a circumferential direction using heat

30、 and pressure. The manufacturing process begins by conventionally extruding a starting stock pipe. This starting stock piece is roughly half the diameter and twice the wall thickness of the finished PVCO pipe (e.g., starting stock with a nominal 3-in. 75-mm diameter and a 0.40-in. 10.2-mm wall thick

31、ness becomes a finished PVCO pipe with a nominal 6-in. 150-mm diameter and a 0.20-in. 5.1-mm wall thickness). The starting stock piece is heated and then circumferentially expanded to its final dimensions. By circumferentially expanding the starting stock piece, a new molecular orientation is achiev

32、ed. This new orientation increases physical and mechanical properties of the pipe. Tensile strength, and hence the hydrostatic design basis (HDB), is substantially increased from 4,000 psi to 7 ,100 psi (27.6 MPa to 49.0 MPa). This standard pertains to 4-in. (100-mm) and larger PVCO pressure pipe ma

33、de from class 12454 material. The PVCO pressure pipe is designed to provide an HDB of 7,100 psi with ductile-iron-pipe-equivalent (DI) outside diameter (OD) dimensions. Previous editions have referenced cast-iron-pipe-equivalent (CI) outside diameters. DIOD and CIOD are one and the same (equal). The

34、 reference to DIOD is to maintain consistency with other AWWA standards. The wall thicknesses are sufficient to provide pressure classes 165 psi, 235 psi, and 305 psi while maintaining a long-term safety fac- tor of 2.0. Design considerations are provided in AWWA Manual M23, PVC PipeDesign and Insta

35、llation, which provides detailed information on PVCO pipe covered by ANSI/ AWWA C909. Recommended installation guidance is provided in ANSI/AWWA C605. Additional information may be found in ANSI/AWWA C110, C153, C900, C905, and C907 for use with the PVCO pipes covered by ANSI/AWWA C909. Fabricated P

Ductile-iron mechanical-joint fittings for use with ANSI/AWWA C909 are covered by ANSI/AWWA C110 and C153. I.B. History. This is the fourth edition of ANSI/AWWA C909.

38、 In 1994, the PVC Pipe and Fittings Committee appointed a subcommittee to develop a standard for PVCO pressure pipe. The first edition of ANSI/AWWA C909 was approved by the AWWA Board of Directors in 1998. Subsequent editions were approved in 2002 and 2009. This edition was approved on Jan. 16, 2016

39、. I.C. Acceptance. In 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 and indirect drinking water additives. Othe

40、r members of the original consortium included the Water Research Foundation (formerly 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 Un

41、ited States, authority to regulate products for use in, or in contact with, drinking water rests with individual states.* Local agencies may choose to impose requirements more stringent than those required by the state. To evaluate the health effects of products and drinking water additives from suc

42、h products, state and local agencies may use various references, including 1. An advisory program formerly administered by USEPA, Office of Drinking Water, discontinued on Apr. 7, 1990. 2. Specific policies of the state or local agency. 3. Two standards developed under the direction of NSF : NSF/ANS

43、I 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. 4. Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other standards considered appropriate by the state or local agency. Various certif

44、ication organizations may be involved in certifying products in accor- dance with NSF/ANSI 61. Individual states or local agencies have authority to accept * Persons outside the United States should contact the appropriate authority having jurisdiction.

46、dit certification organizations within their jurisdictions. Accreditation of certi- fication organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 61 does not stipulate a maximum allowable level (MAL) of a contaminant for substa

47、nces not regulated by a USEPA final maximum contaminant level (MCL). The MALs of an unspecified list of “unregulated contaminants” are based on toxicity testing guidelines (noncarcinogens) and risk characterization methodology (carcinogens). Use of Annex A procedures may not always be identical, dep

48、ending on the certifier. ANSI/AWWA C909 does not address additives requirements. Thus, users of this standard should consult the appropriate state or local agency having jurisdiction in order to 1. Determine additives requirements, including applicable standards. 2. Determine the status of certifications by parties offering to certify products for contact with, or treatment of, drinking water. 3. Determine current information on product certification. II.
