35、t of ANSI*/AWWA C219. I. Introduction. I.A. Background. This standard describes bolted sleeve-type couplings, reducing or transition couplings, and flanged coupling adapters used to join plain-end pipe. It also includes materials of construction, inspection, and testing. I.B. History. The first edit
36、ion of ANSI/AWWA C219 was approved by the AWWA Board of Directors on June 23, 1991. Subsequent editions were approved on June 15, 1997, Jan. 21, 2001, Feb. 12, 2006, and Jan. 23, 2011. This edition was approved on Jan. 14, 2017. I.C. Acceptance. In May 1985, the US Environmental Protection Agency (U
37、SEPA) 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 Foundati
38、on (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 wit
39、h, 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 and local agencies may use various references, including
40、 1. Specific policies of the state or local agency. 2.

42、standards, Food Chemicals Codex, Water Chemicals Codex,* and other standards considered appropriate by the state or local agency. Various certification organizations may be involved in certifying products in accor- dance with NSF/ANSI 61. Individual states or local agencies have authority to accept
43、or accredit 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 fo
44、r substances 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 identi
45、cal, depending on the certifier. ANSI/AWWA C219 does not address additives requirements. Users of this stan- dard 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 certi
46、fications by parties offering to certify products for contact with, or treatment of, drinking water. 3. Determine current information on product certification. II. Special Issues. II.A. Advisory Information on Product Application. Bolted sleeve-type couplings have been used for joining plain-end pip
47、e since the latter part of the nineteenth century. Currently, there are several manufacturers that produce these couplings. Though details differ, couplings of this type work the same way and have similar components: a center sleeve (sometimes called a “middle ring”), end rings (sometimes called “fo
48、llowers”), and threaded fasteners (bolts and nuts) that when tightened, pull the end rings together. These components compress elastomeric gaskets in the space formed between the end rings, center sleeve, and pipes being joined, thereby sealing the coupling-and-pipe combination. II.B. Chlorine and C
49、hloramine Degradation of Elastomers. The selection of materials is critical for water service and distribution piping in locations where there is a possibility that elastomers will be in contact with chlorine or chloramines. Documented research has shown that elastomers such as gaskets, seals, valve seats, and * Both publications available from National Academy of Sciences, 500 Fifth Street, NW, Washington, DC 20001.
