Die Annotation des Normtextes ASTM A1107/A1107M-17(2022) :
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.

1.1?This specification covers the design, material, and minimum performance requirements of resilient connectors used for connections between reinforced concrete structures conforming to Specifications C478 and C913 to corrugated steel drainage pipe conforming to Specifications A760 or A762. 1.1.1?These connectors are designed 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]. 1.1.2?Testing under this standard is limited to hydrostatic pressures. Alternate air and vacuum pressure testing involve unique testing protocols and are not addressed under this standard. 1.1.3?Testing under this standard is conducted in a laboratory as a proof of design certification. Actual field performance testing would be accomplished and accepted under individual project performance standards or pipeline acceptance criteria, which is outside the scope of this standard. Note 1:?Infiltration or exfiltration quantities for an
installed system are dependent upon many factors other than the
connections between manhole structures and pipe, and allowable
quantities must be covered by other specifications and suitable
testing of the installed pipeline and system.
1.2?The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text 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. 1.3?The following precautionary caveat pertains only to the test methods portion, Section 7, of this specification: 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. |
