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 第478页 和 C913 符合规范的波纹钢排水管 A760 或 A762型 . 1.1.1 这些连接器设计用于在管道和人孔或其他结构之间提供正密封，内部和外部静水压力小于10.8 psi[74 KPa]。 1.1.2 本标准下的试验仅限于静水压力。交替空气和真空压力测试涉及独特的测试协议，本标准未对此进行说明。 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独的项目性能标准或管道验收标准完成并验收，这超出了本标准的范围。 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之外的许多因素，允许的量必须包含在其他规范和已安装管道和系统的适当测试中。 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，SI单位显示在括号中。每个系统中规定的值可能不完全相等: 因此，每个系统应独立使用。将两个系统的值合并可能导致不符合标准。 1.3 以下预防性警告仅适用于测试方法部分，第节 7. 本规范的: 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 有关具体的预防说明，请参见 7.2.4 . 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《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 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: 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 7.2.4 . 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.
