This standard covers rubber-gasket joints of the following types for ductile-iron pressure pipe and ductile-iron and gray-iron fittings, valves, hydrants, and other appurtenances for water supply service: mechanical joint; push-on joint; flanged joint; and modifications to push-on and mechanical joints. The main purpose of this standard is to provide the minimum requirements for rubber-gasket joints for ductile-iron pressure pipe and ductile-iron and gray-iron fittings, including requirements and inspection. The major revisions in this edition of ANSI/AWWA C111/A21.11-95 include the following: the format has been changed to AWWA standard style; the acceptance clause (Sec. I.C) has been revised to approved wording; a statement that addresses physical requirements of elastomers other than SBR has been added to Sec. 4.3.4.1; a statement has been added to Sec. 4.2.2 allowing flange joints in 12-in. and smaller sizes to be rated for 350 psi with the use of special gaskets whose rating is supported by performance testing as described in Sec. 4.5; Section 1.1, Figure 1, and Table 2 have been revised to delete mechanical-joint pipe larger than 24 in.; a plus tolerance has been added to the bell flange thickness (L) for pipe and C110 fittings and to the dimensions across the centerlines of the bolt holes (K1 and K2) in Table 2; dimensions have been added to Table 2 for ANSI/AWWA C153/A21.53 fittings for 18- through 24-in. sizes; Figures 11.3 and 11.4 and Tables 11.3 and 11.4 from the previous revision have been combined into Figure 3 and Table 5, respectively; Section 4.3.5, Sec. A.1, and Sec. B.1 have been revised to require compliance of fasteners to Public Law 101-592, the "Fastener Quality Act"; and, dimensional data have been added to Table B1 for 60- and 64-in. flange gaskets.
