1.1 本规范涵盖按标准热塑性塑料管尺寸比和额定水压制成的聚氯乙烯（PVC）管（见附录）。包括PVC塑料管材料和PVC塑料管的分类标准，PVC塑料管命名系统，以及材料、工艺、尺寸、持续压力、爆裂压力、压扁和挤压质量的要求和测试方法。还给出了标记方法。 1.2 本规范所涵盖的产品仅用于分配与管道材料化学相容的加压液体。由于用压缩空气或其他压缩气体测试部件和系统存在固有危险，一些制造商不允许对其产品进行气动测试。气动测试前，请咨询特定的产品/部件制造商，了解其特定的测试程序。 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: 本标准规定了管道和流体处理应用的尺寸、性能和试验要求，但未涉及燃烧气体的排放。 1.3 本规范的文本引用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）不应被视为规范的要求。 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 以下安全隐患警告仅适用于第节测试方法部分 8. ，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。中给出了具体的预防说明 注释9 . 注3: CPVC塑料管（SDR-PR）以前包含在本规范中，现在包含在规范中 F442/F442米 . 注4: 持续和爆裂压力试验要求以及附录中的压力额定值是根据4 in.（100 mm）及以下管道试验获得的应力值计算得出的。然而，对直径高达24英寸（600毫米）的管道进行的测试表明，这些应力值对较大直径的PVC管道有效。 注5: 按照本规范制造的PVC管通常用作管线管。有关溶剂水泥钟形物的详细信息，请参阅规范 D2672 有关扩口弹性接头的详细信息，请参见规范 D3139 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 poly(vinyl chloride) (PVC) pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water (see appendix). 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 safety hazards should a system fail for any reason. Note 2: This standard specifies dimensional, performance and test requirements for plumbing and fluid handling applications, but does not address venting of combustion gases. 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 pipe (SDR-PR), which was formerly included in this specification, is now covered by Specification F442/F442M . Note 4: The sustained and burst pressure test requirements, and the pressure ratings in the appendix, 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) in 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.
