1.1This 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/C478M and pipes, and between precast reinforced concrete pipe and laterals for storm drainage systems.
1.1.1These connectors are designed to prevent soil migration between the pipe and storm sewer structure, and between the pipe and lateral.
1.2The values stated in inch pound or SI units are to be regarded separately as standard. The SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
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) [41 kPa (4.3 m)] 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.
Note 2:For installations that exceed 6 psi (14 ft) [41 kPa (4.3 m)], the user is cautioned to verify the amount of hydrostatic head pressure the connector will experience. If the total pressure applied to the connector exceeds the 6 psi [41 kPa] limits of the specification, the user is advised to contact the connector manufacturer for alternative methods of connecting the pipe, or applicable alternative standards.
1.3The 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 warning statement, see 7.2.4.
1.4This 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.
