Ductile iron and gray iron fittings used for water service are normally furnished with a cementmortar lining in accordance with ANSI/ AWWA C104/A2
34、1.4, CementMortar Lining for Ductile Iron Pipe and Fittings, for internal corrosion protection. 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
35、 gray iron fittings for buried applications in corrosive environments. The purpose of this standard is to provide purchasers and manufacturers with the minimum requirements for protective fusion bonded epoxy coatings and linings for the interior and exterior surfaces of ductile iron and gray iron fi
36、ttings used for water service. The standard describes the material, application, and performance requirements for these coatings and linings and can be referenced in specifications for purchasing fittings with an interior and exterior fusion bonded epoxy coating. History. I.B. American National Stan
37、dards Committee A21 on Cast Iron Pipe and Fittings was organized in 1926 under 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
38、and 1984, the cosecretariats were AGA, AWWA, and NEWWA, with AWWA serving as 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 manu
39、als that address ductile iron pressure pipe for water supply service and ductile 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
40、 A21 is conducted by subcommittees. The scope of Subcommittee 4, Coatings and Linings, includes the periodic review of current A21 standards for interior and exterior protection of ductile iron pipe and ductile iron * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York

All Rights Reserved. x and gray iron fittings, the preparation of revisions and new standards when needed, and the examination of other matters pertaining to standards for interior and exterior protection of pipe and fittings. In
42、1994, the AWWA Standards Council approved the development of an AWWA standard for protective fusion bonded epoxy coatings for the interior and exterior surfaces of ductile iron and gray iron fittings for water service and assigned this project to Committee A21. Consequently, Subcommittee 4 submitted
43、 a proposed standard for fusion bonded coatings to Committee A21 in 1997. The first edition of the standard was adopted in 1998. The second edition was adopted in 2003. This third edition of C116 was approved by the AWWA Board of Directors on Jan. 25, 2009. Acceptance. I.C. In May 1985, the US Envir

Other members of the original consortium includ

The American Water Works Association (AWWA) and the Association of State Drinking Water Administrators (ASDWA) joined later. In the United States, authority to
