1.1 本规范涵盖了带内衬的环形波纹型壁聚乙烯管和配件的要求和试验方法。涵盖的内径为50 毫米至1500毫米[2 英寸至60英寸]。 1.2 本规范的要求旨在为地下和陆地排水系统提供非压力（重力流）管道和配件，这些管道和配件不在超载压头下运行。 注1: 按照本规范生产的管道和配件应按照实践进行安装 天2321 或实践 F449英镑 基于各自标准内的直径限制。 注2: 地下和陆地排水系统主要适用于地下水位控制、暴雨排水和农业排水应用的非市政或私人设施。 根据本规范提供的产品不适用于任何卫生下水道或市政雨水下水道应用。 1.3 本规范涵盖使用环形外部波纹型材的带有内衬的管道和配件( 图1 ). 1.4 本规范允许根据第 5. . 1.5 单位- 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值不一定是精确的等效值；因此，为了确保符合标准，每个系统应独立使用，并且两个系统的值不应合并。 1.6 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。 1.7 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 requirements and test methods for annular corrugated profile wall polyethylene pipe and fittings with an interior liner. The inside diameters covered are 50 mm to 1500 mm [2 in. to 60 in.]. 1.2 The requirements of this specification are intended to provide non-pressure (gravity flow) pipe and fittings for underground use for subsurface and land drainage systems, which do not operate under surcharge pressure heads. Note 1: Pipe and fittings produced in accordance with this specification are be installed in compliance with Practice D2321 or Practice F449 based on diameter limitations within the respective standards. Note 2: Subsurface and land drainage systems pertain principally to non-municipal or private facilities for water table control, storm drainage and agricultural drainage applications. The products supplied under this specification are not intended for any sanitary sewer or municipal storm sewer applications. 1.3 This specification covers pipe and fittings with an interior liner using an annular exterior corrugated profile ( Fig. 1 ). 1.4 This specification permits the use of recycled materials for pipe in accordance with the requirements in Section 5 . 1.5 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.6 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. 1.7 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.
