1.1 本规范涵盖混凝土重力流污水管道的柔性防漏接头，使用橡胶垫圈密封接头，其中可测量或定义的渗透或渗出是设计的一个因素。本规范涵盖了接头的设计以及在所有其他方面符合规范的管道所用橡胶垫圈的要求 C14 , C76 , C655 , C985 和 C1417 ，前提是，如果允许的尺寸变化存在冲突，则应以本规范的要求为准。 注1: 已安装管道的渗透或渗出量取决于接头以外的许多因素，允许的量必须包括在已安装管道和系统的其他规范和适当测试中。 本规范仅涵盖橡胶垫圈接头的设计、材料和性能。当根据第节对工厂进行测试时，本规范所涵盖的接头适用于不泄漏的高达13 psi的静水压力 10 . 1.2 以英寸磅为单位的数值应视为标准。本标准不包括其他计量单位。 1.3 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。 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》中确立的国际公认的标准化原则制定的。

1.1 This specification covers flexible leak resistant joints for concrete gravity flow sewer pipe using rubber gaskets for sealing the joints, where measurable or defined infiltration or exfiltration is a factor of the design. The specification covers the design of joints and the requirements for rubber gaskets to be used therewith, for pipe conforming in all other respects to Specifications C14 , C76 , C655 , C985 , and C1417 , provided that, if there is conflict in permissible variations in dimension, the requirements of this specification shall govern for joints. Note 1: Infiltration or exfiltration quantities for an installed pipeline are dependent upon many factors other than the joints, and allowable quantities must be covered by other specifications and suitable testing of the installed pipeline and system. This specification covers the design, material, and performance of the rubber gasket joint only. Joints covered by this specification are for hydrostatic pressures up to 13 psi without leakage, when plant tested in accordance with Section 10 . 1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. 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. 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.
