Standard Specification for Joints for Concrete Pipe and Manholes, Using Rubber Gaskets

ABSTRACT
This specification covers flexible watertight joints for concrete pipe and precast manhole sections, using rubber gaskets for sealing the joints, where infiltration or exfiltration is a factor in the design. The numerical values in this specification are not presented in metric or SI units, but rather, in inch-pound units only. All rubber gaskets shall meet the dimensions, tolerances, and physical requirements of both standard gasket and oil resistant gasket requirements. Assembled joints should pass the following performance test without leakage at the joints: pipes in straight alignment, and pipes in maximum deflected position.
SCOPE
1.1 This specification covers flexible watertight joints for concrete pipe and precast manhole sections, using rubber gaskets for sealing the joints, where infiltration or exfiltration is a factor in 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, Specification C 76, or Specificaton C 507 and precast manhole section conforming in all other respects to Specification C 478, provided that if there is conflict in permissible variations in dimensions the requirements of this specification for joints shall govern.
1.2 A complete metric companion to Specification C 443 has been developed-C 443M; therefore, no metric equivalents are presented in this specification.
Note 1—This specification covers the design, material, and performance of the rubber gasket joint only. Joints covered by this specification are normally adequate for hydrostatic pressures up to 13 psi (30 ft) without leakage, when tested in accordance with Section . 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.
