(Specification)Standard Specification for Storm Drain Resilient Connectors Between Reinforced Concrete Storm Sewer Structures, Pipes, and Laterals
Standard Specification for Storm Drain Resilient Connectors Between Reinforced Concrete Storm Sewer Structures, Pipes, and Laterals
ABSTRACT
This specification covers the minimum performance and material requirements for resilient connectors used for connections between precast reinforced concrete storm sewer structures and pipes, and between precast reinforced concrete pipe and laterals for storm drainage systems. These connectors are designed to prevent soil migration between the pipe and storm sewer structure, and between the pipe and lateral. Resilient materials for connectors, filler rings, and mechanical devices shall be tested, and shall conform to the specified values chemical resistance, tensile strength, elongation hardness, accelerated oven-aging, compression set, water absorption, ozone resistance, low-temperature brittle point, and tear resistance. The design of the connector and the pipe stubs are detailed.
SCOPE
1.1 This specification covers the minimum performance and material requirements for resilient connectors used for connections between precast reinforced concrete storm sewer structures conforming to Specification C478 and pipes, and between precast reinforced concrete pipe and laterals for storm drainage systems.
1.1.1 These connectors are designed to prevent soil migration between the pipe and storm sewer structure, and between the pipe and lateral.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are for information only.Note 1—This specification covers the design, material, and performance of the resilient connection only. Connections covered by this specification are adequate for hydrostatic pressures up to 6 psi (14 ft) without leakage when tested in accordance with Section 7. Infiltration quantities for an installed system are dependent upon many factors other than the connections between storm sewer structures and pipe, and allowable quantities must be covered by other specifications and suitable testing of the installed pipeline and system.
1.3 The following precautionary caveat pertains only to the test methods portion, Section 7, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific warning statement, see 7.2.4.
