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 and filler rings shall be manufactured from natural or synthetic rubber and shall conform to the test requirements prescribed for (1) chemical resistance to sulfuric and hydrochloric acid, (2) tensile strength, (3) elongation at break, (4) hardness, (5) accelerated oven-aging, (6) compression set, (7) water absorption, (8) ozone resistance, (9) low-temperature brittle point, and (10) tear resistance. If a splice is used in the manufacture of the seal, its strength shall be such that the seal shall withstand the specified bend with no visible separation. Requirements for the devices to be used for mechanical compressing and deformation of the resilient materials are given. The principles of design of the connector including locations for positive seal and installation of pipe stubs, the basis of acceptance, and the requirements for leakage testing by shear test method are detailed.
