Anotácia

This specification covers the design, material, and minimum performance requirements for resilient connectors used to provide a positive seal between the pipe and manholes or other structures subjected to internal and external hydrostatic pressures less than 10.8 psi [74 KPa]. Testing under this specification is limited to hydrostatic pressures and conducted in a laboratory as a proof of design certification. Resilient materials for connectors and filler rings shall be manufactured from natural or synthetic rubber, shall display no fracture at -40 ?F [-40 ?C], and shall meet a minimum tear resistance of 200 lbf/in [34 kN/m] when tested. Expansion rings, tension bands, and take-up devices used for mechanically compressing the resilient portion of the connector against the pipe, manhole or wastewater structure shall be made from a material or materials in combination that will ensure durability, strength, resistance to corrosion, and continued resistance to leakage. Bolts, nuts, and other threaded items used with joining systems shall be zinc coated by one of the following processes: hot-dip process, electroplating process, or mechanical process. The same processes shall be used for zinc coating of other hardware items used with coupling bands.This specification also covers requirements for basis of acceptance, test methods, and product marking.
