1.1 本规程描述了一种两步法（底漆和溶剂粘合剂），将聚氯乙烯（PVC）或氯化聚氯乙烯（CPVC）管道和管道组件与锥形插座连接起来。 注1: 在当地法规允许的情况下，非压力应用中可能允许简化程序。 注2: 如果规范和制造商的安装说明之间存在冲突，则适用更严格的规定。 1.2 本规程涵盖的产品仅适用于与管道材料化学相容的加压液体的分配。 由于使用压缩空气或其他压缩气体测试组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。在气动测试之前，请咨询特定的产品/组件制造商，了解其特定的测试程序。 注3: 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。 1.3 本标准规程不涉及在不使用底漆的情况下，使用溶剂型粘合剂将管道和管道组件与锥形插座连接的一步法。 一步法见实践 F3328 . 1.4 所涵盖的技术适用于将PVC连接到PVC或CPVC连接到CPVC管道和带锥形插座的管道组件。在本标准惯例的其余部分中，术语“带锥形插座的管道组件”，无论是承口管、插口连接还是任何其他类型的锥形连接，都将被称为“配件” 1.5 适用于连接管道和配件的PVC和CPVC管道、管道组件和溶剂型粘合剂的部分标准清单见 附录X1 . 1.6 以英寸为单位的值- 磅单位应被视为标准单位。括号中给出的值是对国际单位制的数学转换，仅供参考，不被视为标准值。 1.7 本规程的文本引用了提供解释性材料的注释和脚注。这些注释和脚注（不包括表格和图表中的注释和脚注）不应被视为本规程的要求。 1.8 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.9 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。 =====意义和用途====== 5.1 溶剂型水泥粘合剂/安装人员必须遵循所有程序，在车间操作或现场生产出始终如一的坚固和无泄漏的接缝。

1.1 This practice describes a two-step (primer and solvent cement) method of joining poly(vinyl chloride) (PVC) or chlorinated poly(vinyl chloride) (CPVC) pipe and piping components with tapered sockets. Note 1: Simplified procedures may be allowed in non-pressure applications where local codes permit. Note 2: Where conflicts occur between the code and the manufacturer’s installation instructions, the more restrictive provisions apply. 1.2 The products covered by this practice are intended for use with the distribution of pressured 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 3: 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. 1.3 This standard practice does not address the one-step method of joining pipe and piping components with tapered sockets with solvent cement without the use of primer. For the one-step method see Practice F3328 . 1.4 The techniques covered are applicable to joining PVC to PVC or CPVC to CPVC pipe and piping components with tapered sockets. In the remainder of this standard practice, the term “piping components with tapered sockets”, whether it be bell end pipe, spigot connections, or any other type of tapered connections, will be referred to as “fittings.” 1.5 A partial list of standards for PVC and CPVC pipe, piping components, and solvent cements suitable for use in joining pipe and fittings is given in Appendix X1 . 1.6 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. 1.7 The text of this practice references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the practice. 1.8 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. 1.9 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. ====== Significance And Use ====== 5.1 A solvent cement bonder/installer must follow all procedures to produce consistently strong and leak-free joints, either in shop operations or in the field.
