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.
Note 2: For installations that exceed 6 psi (14 ft), 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 limits of the specification, the user
is advised to contact the connector manufacturer for alternative
methods of connecting the pipe, or applicable alternative
standards.
1.3 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 warning statement, see 7.2.4. 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. |
