1.1 本规范涵盖了用于符合规范的钢筋混凝土结构之间连接的弹性连接器的设计、材料和最低性能要求 C478/C478M 和 C913 符合规范的环形波纹型材壁高密度聚乙烯（HDPE）和聚丙烯（PP）排水管和污水管 F2306/F2306M , F2648/F2648M , F2763/F2763M , F2764/F2764M , F2881/F2881M 和 F2947/F2947M . 1.1.1 这些连接器设计用于在管道和人孔或承受小于10.8 psi[74 KPa]的内部和外部静水压力的其他结构之间提供正密封。 1.1.2 本标准下的测试仅限于静水压力。 备用空气和真空压力测试涉及独特的测试协议，本标准不涉及。 1.1.3 本标准下的测试在实验室进行，作为设计认证的证明。实际现场性能测试将根据单个项目性能标准或管道验收标准完成和验收，这不在本标准的范围内。 注1: 已安装系统的渗透或渗出量取决于除人孔结构和管道之间的连接以外的许多因素，其他规范和已安装管道和系统的适当测试必须涵盖允许量。 注2: 本规范可适用于其他类型的塑料排水管。 咨询管道制造商以了解本标准的适用性。 1.2 以英寸-磅单位或国际单位表示的数值应单独视为标准值。在文本中，国际单位用括号表示。每个系统中规定的值可能不是精确的等效值:因此，每个系统应独立于另一个系统使用。将两个系统的值合并可能会导致不符合标准。 1.3 以下预防性警告仅适用于试验方法部分第节 7. . 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 有关具体的预防声明，请参阅 7.2.3 . 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

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.
