Ductile iron and gray iron fittings used for water service are normally furnished with a cementmortar lining in accordance with ANSI/ AWWA C104/A21.4, CementMortar Lining for Ductile Iron Pipe and Fittings, for internal corrosion pro
33、tection. Additionally, polyethylene encasement in accordance with ANSI/AWWA C105/A21.5, Polyethylene Encasement for Ductile Iron Pipe Systems, is normally used for external corrosion protection of ductile iron and gray iron fittings for buried applications in corrosive environments. The purpose of t
34、his standard is to provide purchasers and manufacturers with the minimum requirements for protective fusion bonded coatings and linings for the inte rior and exterior surfaces of ductile iron and gray iron fittings used for water service. The standard describes the material, application, and perform
35、ance requirements for these coatings and linings and can be referenced in specifications for purchasing fittings with an interior and exterior fusion bonded epoxy or polyolefin coating. I.B. History. American National Standards Committee A21 on Cast Iron Pipe and Fittings was organized in 1926 under
36、 the sponsorship of the American Gas Association (AGA), the American Society for Testing and Materials (ASTM), the American Water Works Association (AWWA), and the New England Water Works Association (NEWWA). Between 1972 and 1984, the cosecretariats were AGA, AWWA, and NEWWA, with A WWA serving as
37、administrative secretariat. In 1984, the committee became an AWWA committee called AWWA Standards Committee A21 on Ductile Iron Pipe and Fittings. The present scope of Committee A21 activity is to develop standards and manuals that address ductile iron pressure pipe for water supply service and duct
38、ile iron and gray iron fittings for use with such pipe. These standards and manuals include design, dimensions, materials, coatings, linings, joints, accessories, and methods of inspection and testing. The work of Committee A21 is conducted by subcommittees. The scope of Subcom mittee 4, Coatings an
39、d Linings, includes the periodic review of current A21 standards for interior and exterior protection of ductile iron pipe and ductile iron and gray iron * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036.

In 1994, the AWWA Standards Council approved the development of an AWWA standard for pro
41、tective fusion bonded epoxy coatings for the interior and exterior sur faces of ductile iron and gray iron fittings for water service and assigned this project to Committee A21. Consequently, Subcommittee 4 submitted a proposed standard for fusion bonded coatings to Committee A21 in 1997. The first
42、edition of the stan dard was adopted in 1998. Subsequent revisions to ANSI/AWWA C116/A21.16 were approved by the AWWA Board of Directors in 2003 and 2009. This fourth edition of C116 was approved on June 7, 2015. I.C. Acceptance. In May 1985, the US Environmental Protection Agency (USEPA) entered in
43、to 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 Foundation (formerly Aw
44、waRF) 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 with, drinking wat
45、er 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 1. An advisory
46、 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/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water Sy
47、stem 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. * NSF International, 789 North Dixboro Road, Ann Arbor, MI 48113.
