1.1 本规程描述了在化粪池沥滤场、帷幕排水沟以及从化粪池到沥滤场中处理和安装热塑性塑料管和波纹管的程序。正确安装可确保管道将部分处理后的废水顺利输送和分配至淋滤场，以便通过土壤吸收进行额外处理和处置。帷幕或周边排水沟将起到保护沥滤场土壤吸收能力的作用。 1.2 为确保符合当地监管规定，应联系当地审批机构（当地卫生部门等）了解浸出现场设计材料和安装的具体要求。 1.3 本规程适用于根据以下ASTM规范制造的管道和管件: 1.3.1 从储罐运输至浸出场:规范 D2680 , D2729 , D2751 , D2852 , D3034 , F405 , F758 , F789 , F810 , F891 , F892 和 F949 . 1.3.2 多孔，用于沥滤场或帷幕排水:规范 D2729 , D2751 , F405 , F810 , F891 和 F892 . 1.4 根据本规程安装的管道应具有中引用的适当产品标准中规定的最小管道刚度 1.3.1 或 1.3.2 . 1.5 以英寸-磅为单位的数值应视为标准值。 括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 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。 有关具体的预防说明，请参阅第节 7. . 1.7 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 practice describes procedures for handling and installing thermoplastic pipe and corrugated pipe in septic tank leach fields, curtain drains, and from the septic tank to the leach field. Proper installation ensures that the pipe will satisfactorily convey and distribute partially treated waste water to a leaching field for additional treatment and disposal by soil absorption. The curtain or perimeter drain will function to protect the soil absorption capacity of the leach field. 1.2 To ensure compliance with local regulatory provisions, the local approving authority (local health departments and so forth) should be contacted regarding specific requirements for leach field design materials and installation. 1.3 This practice applies to pipe and fittings made under each of the following ASTM specifications: 1.3.1 For transport from tank to leach field: Specifications D2680 , D2729 , D2751 , D2852 , D3034 , F405 , F758 , F789 , F810 , F891 , F892 , and F949 . 1.3.2 Perforated, for use in leach field or curtain drain: Specifications D2729 , D2751 , F405 , F810 , F891 , and F892 . 1.4 Pipe intended for installation in accordance with this practice should have a minimum pipe stiffness as specified in the appropriate product standard referenced in 1.3.1 or 1.3.2 . 1.5 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. 1.6 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. For specific precautionary statements, see Section 7 . 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.
