Anotácia textu normy ASTM C1478/C1478M-20 :
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, filler rings, and mechanical devices shall be tested, and shall conform to the specified values chemical resistance, tensile strength, elongation hardness, accelerated oven-aging, compression set, water absorption, ozone resistance, low-temperature brittle point, and tear resistance. The design of the connector and the pipe stubs are detailed.

Doplňujúce informácie
| 1. 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 C478/C478M 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 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.
1.3 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. |
