【国外标准】 Standard Specification for Resilient Connectors Between Reinforced Concrete Manhole Structures and Corrugated Dual- and Triple-Wall Polyethylene and Polypropylene Pipes

This specification covers the design, material, and minimum performance requirements of resilient connectors used for connections between reinforced concrete manhole structures and corrugated high density polyethylene drainage pipes. These connectors are designed to provide a positive seal between the pipe and manholes or other structures subjected to internal and external hydrostatic pressures. The design of the connector shall be such that positive seal is accomplished at two locations: (1) between the connector and the wall of the manhole or structure and (2) between the connector and the pipe. The connectors shall be tested for hydrostatic pressure test to meet the requirements prescribed.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/C478M and C913 to annular corrugated profile wall high density polyethylene (HDPE) and polypropylene (PP) drainage and sewer pipe conforming to Specifications F2306/F2306M, F2648/F2648M, F2763/F2763M, F2764/F2764M, F2881/F2881M and F2947/F2947M.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.NOTE 2: This specification may be applied to other types of plastic drainage pipe. Consult with manufacturer of pipe for applicability to this standard.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 non-conformance with the standard.1.3 The following precautionary caveat pertains only to the test methods portion, Section 7. 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 precaution statement, see 7.2.3.1.4 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.
