1.1 This specification covers the minimum performance and material requirements for resilient connectors used for connections between reinforced concrete manholes conforming to Specification C478 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 C923 has been developed—C923M; therefore, no metric equivalents are presented in this specification. 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
13 psi (30 ft) without leakage when tested in accordance with
Section 7. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific precaution statement, see 7.2.5. 1.4 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. |
