1.1 本规范涵盖了与按规范制造的管道一起使用的制造或模制聚氯乙烯（PVC）密封下水道配件的要求和测试方法 D3034 , F679 , F891 或 F1760 . 装配配件可以由管道、管道和注塑件的组合或注塑件制造。带垫圈的下水道配件配置可能包括一个或多个插口。 1.2 本规范的要求是提供适用于污水和地表水的无压排水以及涉及地下排水的应用的预制或模制PVC密封配件。 注1: 当使用排水沟和下水道中不常见的化学品或温度超过140℃时，只有在获得管理法规机构的特别批准后，才能安装工业废水管道 华氏度（60 °C），或两者兼有。 1.3 根据惯例，按照本规范生产的管件应与管道一起安装 D2321 . 1.4 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。 1.5 以下预防性警告仅适用于试验方法部分，第 10 ，符合本规范。 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。 1.6 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 specification covers requirements and test methods for fabricated or molded poly(vinyl chloride) (PVC) gasketed sewer fittings to be used with piping manufactured to Specifications D3034 , F679 , F891 or F1760 . Fabricated fittings may be manufactured from pipe, or from a combination of pipe and injection molded parts, or from injection molded parts. Gasketed sewer fitting configurations may include one or more spigot outlets. 1.2 The requirements of this specification are to provide fabricated or molded PVC gasketed fittings suitable for non-pressure drainage of sewage and surface water, as well as applications involving subsurface drainage. Note 1: Industrial waste lines should be installed only with the specific approval of the governing code authority when using chemicals not commonly found in drains and sewers or temperatures in excess of 140 °F (60 °C), or both. 1.3 Fittings produced to this specification are intended to be installed with pipe, in accordance with Practice D2321 . 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 to the test method portion only, Section 10 , 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.
