Standard Specification for Storm Drain Resilient Connectors Between Reinforced Concrete Storm Sewer Structures, Pipes, and Laterals
The following bibliographic material is provided to assist you with your purchasing decision:
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 and filler rings shall be manufactured from natural or synthetic rubber and shall conform to the test requirements prescribed for (1) chemical resistance to sulfuric and hydrochloric acid, (2) tensile strength, (3) elongation at break, (4) hardness, (5) accelerated oven-aging, (6) compression set, (7) water absorption, (8) ozone resistance, (9) low-temperature brittle point, and (10) tear resistance. If a splice is used in the manufacture of the seal, its strength shall be such that the seal shall withstand the specified bend with no visible separation. Requirements for the devices to be used for mechanical compressing and deformation of the resilient materials are given. The principles of design of the connector including locations for positive seal and installation of pipe stubs, the basis of acceptance, and the requirements for leakage testing by shear test method 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 C 478
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.
