标准简介适用范围：
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 inch-pound units, but rather, in metric or SI 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.1.1 This specification covers flexible leak-resistant 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 C14, Specification C76, or Specification C507 and precast manhole section conforming in all other respects to Specification C478/C478M, 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 C443 has been developed—C443M; therefore, no metric equivalents are presented in this specification.NOTE 1: This specification covers the design and performance of the rubber gasket joint only. Joints covered by this specification are adequate for hydrostatic pressures up to 13 psi (30 ft), when tested in accordance with Section 9. 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.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
