1.1 本规范涵盖了用于符合规范的预制钢筋混凝土雨水管结构之间连接的弹性连接器的最低性能和材料要求 C478型 和管道，以及暴雨排水系统的预制钢筋混凝土管和支管之间。 1.1.1 这些连接器旨在防止管道和雨水管结构之间以及管道和侧面之间的土壤迁移。 1.2 本规范是SI的配套规范 C1478 . 注1: 本规范仅涵盖弹性连接的设计、材料和性能。本规范涵盖的连接件足以承受高达41 kPa（4）的静水压。 3 m）根据第节进行测试时无泄漏 7. . 已安装系统的渗透量取决于除雨水管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的渗透量。 注2: 对于超过41 kPa（4.3 m）的安装，应提醒用户验证接头将承受的静水压头压力。如果施加在连接器上的总压力超过本规范的41 kPa限制，建议用户联系连接器制造商，以获取连接管道的替代方法或适用的替代标准。 1.3 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。 有关特定警告声明，请参阅 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（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 minimum performance and material requirements for resilient connectors used for connections between precast reinforced concrete storm sewer structures conforming to Specification C478 and pipes, and between precast reinforced concrete pipe and laterals for storm drainage systems. 1.1.1 These connectors are designed to prevent soil migration between the pipe and storm sewer structure, and between the pipe and lateral. 1.2 This specification is the SI companion to C1478 . Note 1: This specification covers the design, material, and performance of the resilient connection only. Connections covered by this specification are adequate for hydrostatic pressures up to 41 kPa (4.3 m) without leakage when tested in accordance with Section 7 . Infiltration quantities for an installed system are dependent upon many factors other than the connections between storm sewer structures and pipe, and allowable quantities must be covered by other specifications and suitable testing of the installed pipeline and system. Note 2: For installations that exceed 41 kPa (4.3 m), the user is cautioned to verify the amount of hydrostatic head pressure the connector will experience. If the total pressure applied to the connector exceeds the 41 kPa limits of the specification, the user is advised to contact the connector manufacturer for alternative methods of connecting the pipe, or applicable alternative standards. 1.3 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 warning 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.
