1.1 本实践描述了通过安装树脂浸渍的柔性管来重建管道和导管（直径2英寸至108英寸）的程序，该柔性管通过使用静水头或气压倒入现有导管中。通过循环热水、在管内引入受控蒸汽或通过光引发反应来固化树脂。固化后，成品管将是连续且紧密配合的。这种重建过程用于各种重力和压力应用，例如卫生下水道、雨水下水道、工艺管道、电气导管和通风系统。 1.2 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准。1.3 本标准的正文参考了提供解释材料的注释和脚注。这些注释和脚注（不包括表格和图表中的注释和脚注）不应被视为标准的要求。 1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。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法规限制的适用性。 具体注意事项请参见 7.4.2 . 1.5 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。======意义和用途====== 4.1 本实践供设计者和指定者、监管机构、业主和检查组织使用，他们通过使用倒置穿过现有管道的树脂浸渍管来参与管道修复。

1.1 This practice describes the procedures for the reconstruction of pipelines and conduits (2 in. to 108 in. diameter) by the installation of a resin-impregnated, flexible tube which is inverted into the existing conduit by use of a hydrostatic head or air pressure. The resin is cured by circulating hot water, introducing controlled steam within the tube, or by photoinitiated reaction. When cured, the finished pipe will be continuous and tight-fitting. This reconstruction process is used in a variety of gravity and pressure applications such as sanitary sewers, storm sewers, process piping, electrical conduits, and ventilation systems. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.4 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 specific precautionary statements, see 7.4.2 . 1.5 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. ====== Significance And Use ====== 4.1 This practice is for use by designers and specifiers, regulatory agencies, owners, and inspection organizations who are involved in the rehabilitation of conduits through the use of a resin-impregnated tube inverted through the existing conduit.
