1. Scope

1.1 This specification covers the minimum performance and material requirements for resilient connectors used for connections between reinforced concrete manholes conforming to Specification C 478 and pipes, between wastewater structures and pipes, and between precast reinforced concrete pipe and laterals.

1.1.1 These connectors are designed to minimize leakage between the pipe and manhole, and between the pipe and lateral.

1.2 A complete metric companion to Specification C 923 has been developed-C 923M; therefore, no metric equivalents are presented in this specification.

Note 1This specification covers the design, material, and performance of the resilient connection only. Connections covered by this specification are 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 system are dependent upon many factors other than the connections between manhole 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 precaution statement, see 7.2.5.
