WK47 New Standard Specification for Joints for Concrete Gravity Flow Sewer Pipe Using Rubber Gaskets

Developed by Subcommittee: C13.08
See Related Work by this Subcommittee
Date Initiated: 02-07-2003

1. Scope

1.1 This specification covers flexible watertight joints for concrete gravity flow sewer pipe using rubber gaskets for sealing the joints where measurable or defined infiltration or exfiltration is a factor of the design. The specification covers the design of joints and the requirements for rubber gaskets to be used therewith for pipe conforming in all other respects to Specification C 14, C 76, C 655, C 985, and C 1417 provided that, if there is conflict in permissible variations in dimension, the requirements of this specification for joints shall govern.
Note 1--This specification covers the design, material, and performance of the rubber gasket joint only. Joints covered by this specification are for hydrostatic pressures up to 13 psi (90 kPa) without leakage when plant tested in accordance with Section 10. Infiltration or exfiltration quantities for an installed pipeline are dependent upon many factors other than the joints, and allowable quantities must be covered by other specifications and suitable testing of the installed pipeline and system.
