33、nformation only and is not a part of ANSI*/AWWA C222. I. Introduction. I.A. Background. Fast-setting, very high solids polyurethanes were first used in North America to protect steel underground fuel storage tanks from corrosion in the mid-1970s. The materials were also used to protect oil and gas p

34、ipelines in Europe at approximately the same time. Because of further development of the technology during the 1980s, polyurethanes have been used successfully in water and wastewater pipelines and tanks. I.B. History. In April 1996, the AWWA Standards Council authorized the Steel Pipe Committee to

35、develop a new standard for the use of polyurethanes on the interior and exterior of steel water pipe and fittings. The first edition of ANSI/ AWWA C222 was approved by the AWWA Board of Directors on June 20, 1999. The second edition of this standard was approved on June 8, 2008. This edition was app

36、roved on Jan. 20, 2018. 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

37、 water additives. Other 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 and the Association of State Drinking Water Administrators (ASDWA) joined

38、later. In the United 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 add

39、itives from such products, state and local agencies may use various references, including * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036. Water Research Foundation, 6666 West Quincy Avenue, Denver, CO 80235. Persons outside the United States should con

40、tact the appropriate authority having jurisdiction. Copyright 2018 American Water Works Association. All Rights Reserved. x 1. Specific policies of the state or local agency. 2. Two standards developed under the direction of NSF: *NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NS

41、F/ANSI 61, Drinking Water System ComponentsHealth Effects. 3. Other references, including AWWA 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 i

42、n accordance with NSF/ANSI 61. Individual states or local agencies have authority to accept or accredit certification organizations within their jurisdictions. Accreditation of certification organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and Evaluation Procedur

43、es,” to NSF/ANSI 61 does not stipulate a maximum allowable level (MAL) of a contaminant for 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 char

44、acterization methodology (carcinogens). Use of Annex A procedures may not always be identical, depending on the certifier. ANSI/A WWA C222 does not address additives requirements. Users of this standard should consult the appropriate state or local agency having jurisdiction in order to 1. Determine

45、 additives requirements, including applicable standards. 2. Determine the status of certifications by all 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. Soluble Salts. Solubl

46、e salts and other inorganic contaminants on a prepared steel surface have been known to influence coating performance. Procedures for determining the presence of these contaminants, the method of quantifying them, and the acceptable levels are currently being evaluated by technical organizations ser

47、ving the coating and lining industry. II.B. Surface Cleanliness. ISO 8502-3 may be used to assess the substrate cleanliness per the manufacturers recommendation. * NSF International, 789 North Dixboro Road, Ann Arbor, MI 48105.
