1.1 本规范涵盖了按照附表40、80和120尺寸和额定水压力制造的聚氯乙烯（PVC）管（见 附录X1 ). 包括PVC塑料管材料和PVC塑料管的分类标准、PVC塑料管的命名系统，以及材料、工艺、尺寸、持续压力、爆裂压力、压扁和挤出质量的要求和测试方法。给出了标记方法。 1.2 本规范涵盖的产品仅用于分配与管道材料化学相容的加压液体。由于与使用压缩空气或其他压缩气体测试组件和系统相关的固有危险，一些制造商不允许对其产品进行气动测试。在气动测试之前，咨询特定产品/组件制造商，了解其特定测试程序。 注1: 加压（压缩）空气或其他压缩气体含有大量储存的能量，如果系统因任何原因发生故障，这些能量会带来严重的安全隐患。 注2: 本标准仅规定了管道和流体处理应用的尺寸、性能和测试要求。它不包括使用这些产品排放燃烧气体的规定。UL 1738是一个标准，它确实包括了烟气排放产品（包括PVC）的具体测试和标记要求。 1.3 本规范的文本参考了提供解释材料的注释、脚注和附录。这些注释和脚注（不包括表和图中的注释和脚注）不应视为本规范的要求。 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 以下安全危险警告仅适用于测试方法部分第节 8. ，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。 具体预防说明见 附注9 . 注3: CPVC塑料管，附表40和80，以前包含在本规范中，现在包含在本规范中 F441/F441M . 注4: 持续和爆破压力试验要求，以及 附录X1 ，根据在管道4上进行的试验获得的应力值计算。（100 mm）及以下。然而，在24毫米大的管道上进行的测试 在里面(600 mm）直径表明，这些应力值适用于较大直径的PVC管。 注5: 根据本规范制造的PVC管通常采用波纹管作为管线管。有关溶剂水泥钟的详细信息，请参阅规范 D2672 有关钟形弹性接头的详细信息，请参阅规范 D3139页 和 D3212 . 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 poly(vinyl chloride) (PVC) pipe made in Schedule 40, 80, and 120 sizes and pressure-rated for water (see Appendix X1 ). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of nomenclature for PVC plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given. 1.2 The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems with compressed air or other compressed gases some manufacturers do not allow pneumatic testing of their products. Consult with specific product/component manufacturers for their specific testing procedures prior to pneumatic testing. Note 1: Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious saftey hazards should a system fail for any reason. Note 2: This standard specifies dimensional, performance and test requirements for plumbing and fluid handling applications only. It does not include provisions for the use of these products for venting of combustion gases. UL 1738 is a standard that does include specific testing and marking requirements for flue gas venting products, including PVC. 1.3 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification. 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 safety hazards caveat pertains only to the test methods portion, Section 8 , 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. A specific precautionary statement is given in Note 9 . Note 3: CPVC plastic pipes, Schedules 40 and 80, which were formerly included in this specification, are now covered by Specification F441/F441M . Note 4: The sustained and burst pressure test requirements, and the pressure ratings in the Appendix X1 , are calculated from stress values obtained from tests made on pipe 4 in. (100 mm) and smaller. However, tests conducted on pipe as large as 24 in. (600 mm) diameter have shown these stress values to be valid for larger diameter PVC pipe. Note 5: PVC pipe made to this specification is often belled for use as line pipe. For details of the solvent cement bell, see Specification D2672 and for details of belled elastomeric joints, see Specifications D3139 and D3212 . 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.
