31、t of ANSI*/AWWA C906. I. Introduction. I.A. Background. This standard describes outside diameter (OD) controlled polyethylene (PE) pressure pipe and fittings in diameters ranging from 4 in. through 65 in. (100 mm through 1,650 mm) for use primarily in the construction and rehabilitation of water dis
32、tribution and transmission systems. This document describes pipes and fittings made from PE materials with standard PE material designation codes PE 2606, PE 2706, PE 2708, PE 3608, PE 3708, PE 3710, PE 4608, PE 4708, and PE 4710. Pipes are classified in accordance with pipe dimension ratios (DRs) r
33、anging from 7.0 to 32.5. The resultant combinations of PE material designation codes and DRs yield pipe with pressure classes (PCs) ranging from 40 to 333 psig (276 to 2,300 kPa) for water, wastewater, and reclaimed water at 80F (27C) and lower temperatures. PC ratings are reduced for higher service
34、 tem- peratures. See AWWA Manual M55 for information about the use of PE pipe at higher service temperatures. Consult with PE pipe manufacturers about use of PE pipe with different disinfectant types and concentrations. Three standard pipe-diameter systems are described, as follows: Inch OD in accor
35、dance with iron pipe size (IPS) system (ANSI B36.10). Inch OD equivalent to ductile-iron pipe OD (DIOD) in accordance with the ductile-iron pipe sizing system (ANSI/AWWA C150/A21.50). Metric OD equivalents. This standard also includes provision for specifying pipe with custom diameters, wall thickne
36、sses, and dimension ratios. I.B. History. In 1984, the Standards Committee on Thermoplastic Pressure Pipe appointed a subcommittee to prepare a standard covering 4 in. (100 mm) and larger-diameter polyethylene (PE) pressure pipe and fittings. The first proposed draft was submitted to the Thermoplast
37、ic Pressure Pipe Committee by letter ballot in May 1986. The Thermoplastic Pressure Pipe Committee was subsequently dissolved, and its standards responsibilities were divided between two new AWWA standards com- mittees: the PVC Pressure Pipe and Fittings Committee and the Polyolefin Pressure Pipe an
38、d Fittings Committee. The Polyolefin Pressure Pipe and Fittings Committee * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036.

39、 in the fall of 1988. The first edition of ANSI/AWWA C906 was approved by the AWWA Board of Directors on June 21, 1990. Subsequent editions were approved on June 20, 1999, and Jan. 21, 2007 . This edition was approved Jan. 24, 2015. I.C. Acceptance. In May 1985, the US Environmental Protection Agenc
40、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 direct and indirect drinking water additives. Other members of the original consortium included the Water Research Foun
41、dation (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 United States, authority to regulate products for use in, or in contact
42、 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 such products, state, provincial, and local agencies may use various ref
43、erences, including 1. An advisory program formerly administered by USEPA, Office of Drinking Water, discontinued on Apr. 7, 1990. 2. Specific policies of the state, provincial, or local agency. 3. Two standards developed under the direction of NSF : NSF/ANSI 60, Drinking Water Treatment ChemicalsHea
44、lth 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, provincial, or local agency. Various certification organizations may be i
45、nvolved in certifying products in accor- dance with NSF/ANSI 61. Individual states or local agencies have authority to accept or accredit certification organizations within their jurisdictions. Accreditation of certi- fication organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxic
46、ology Review and Evaluation Procedures,” to NSF/ANSI 61 does not stipulate a maximum allowable level (MAL) of a contaminant for substances not * Persons outside the United States should contact the appropriate authority having jurisdiction.

48、nants” are based on toxicity testing guidelines (noncarcinogens) and risk characterization methodology (carcinogens). Use of Annex A procedures may not always be identical, depending on the certifier. ANSI/AWWA C906 does not address additives requirements. Users of this standard should consult the a
49、ppropriate state, provincial, 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.
