This specification covers resilient connectors between reinforced concrete manhole structures, pipes, and laterals. Resilient materials for connectors and filler rings shall be manufactured from natural or synthetic rubber and shall conform to the prescribed requirements. Mechanical devices shall be made from a material or materials in combination that will ensure durability, strength, resistance to corrosion, and have properties that will ensure continued resistance to leakage. The design of pipe connectors and pipe stubs are specified. The physical properties and chemical composition shall conform to the required tests for chemical resistance, tensile strength, elongation at break, hardness, accelerated oven-aging, compression set, water absorption, ozone resistance, low-temperature brittle point, and tear resistance.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
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.
1.3 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.
