1.1 本规范涵盖了在各种重力应用（如卫生下水道、雨水下水道和直径为6至180英寸的工艺管道）以及类似尺寸的非圆形管道（如拱形或椭圆形和矩形）的修复过程中，用于螺旋缠绕管内衬的机制现场制造的挤出聚氯乙烯型材条的材料、尺寸、工艺、刚度系数、挤出质量和标记形式的要求和试验方法。 1.2 根据本规范生产的型材条用于非压力下水道和管道修复中的螺旋缠绕衬管的现场制造，其中螺旋缠绕衬管道被膨胀，直到它压在现有下水道或管道的内表面上，或者，螺旋缠绕衬管路作为固定直径插入现有下水道或导管中，衬管与现有下水道或管路之间的环形空间被灌浆。 1.3 本规范包括仅由 5.1 . 1.4 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.5 以下注意事项仅适用于试验方法部分，第节 11 ，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。 1.6 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====== 9.1 本规范的要求旨在提供适用于现场制造螺旋缠绕衬管的挤出PVC型材条，用于修复重力流条件下输送污水、工艺流程和雨水的现有管道和导管。 注3: 工业废物处理管线应仅在获得认可的规范机构的具体批准后安装，因为在排水沟和下水道中不常见化学品，温度超过140 °F（60 °C）。

1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, stiffness factor, extrusion quality, and a form of marking for extruded poly(vinyl chloride) (PVC) profile strips used for machine made field fabrication of spirally wound pipe liners in the rehabilitation of a variety of gravity applications such as sanitary sewers, storm sewers, and process piping in diameters of 6 to 180 in. and for similar sizes of non-circular pipelines such as arched or oval shapes and rectangular shapes. 1.2 Profile strip produced to this specification is for use in field fabrication of spirally wound liner pipes in nonpressure sewer and conduit rehabilitation, where the spirally wound liner pipe is expanded until it presses against the interior surface of the existing sewer or conduit, or, alternatively, where the spirally wound liner pipe is inserted as a fixed diameter into the existing sewer or conduit and the annular space between the liner pipe and the existing sewer or conduit is grouted. 1.3 This specification includes extruded profile strips made only from materials specified in 5.1 . 1.4 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. 1.5 The following precautionary caveat pertains only to the test method portion, Section 11 , 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. 1.6 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 ====== 9.1 The requirements of this specification are intended to provide extruded PVC profile strip suitable for the field fabrication of spirally wound liner pipe for the rehabilitation of existing pipelines and conduits conveying sewage, process flow, and storm water under gravity flowconditions. Note 3: Industrial waste disposal lines should be installed only with the specific approval of the cognizant code authority since chemicals not commonly found in drains and sewers and temperatures in excess of 140 °F (60 °C) may be encountered.
