1.1 本规范涵盖了由聚氯乙烯（PVC）和氯化聚氯乙烯（CPVC）制成的棒材和棒材挤压型材的材料、尺寸、工艺和财产的要求和试验方法。 1.2 本规范中包含的财产是所涵盖组合物所需的性能。使用第节中给出的分类系统 4. 描述识别对专门应用程序重要的特定特性所必需的需求。 1.3 本规范允许使用再研磨和再生塑料，前提是用再研磨或再生PVC材料生产的产品能够证明在材料分类、物理性能、尺寸和工艺方面符合本标准的要求；并且所使用的再研磨或回收塑料在消费后应用（如化学服务）中没有受到恶劣的环境的影响，这可能在受到机加工或关键应用或两者兼而有之时对最终产品的性能产生不利影响。 1.4 这些值以英寸-磅为单位表示，并被视为所有特性和尺寸表中的标准。出于参考目的，国际单位制也仅包含在表1中。 1.5 以下安全隐患警告仅适用于本规范的测试方法部分: 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。 注1: 目前还没有与该标准等效的ISO。 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 requirements and test methods for the material, dimensions, and workmanship, and the properties of extruded shapes of rods and bars made from poly(vinyl chloride) (PVC), and chlorinated poly(vinyl chloride) (CPVC). 1.2 The properties included in this specification are those required for the compositions covered. Use the classification system given in Section 4 to describe requirements necessary to identify particular characteristics important to specialized applications. 1.3 This specification allows for the use of regrind and recycled plastics providing products produced from regrind or recycled PVC material can be shown to meet the requirements of this standard with regard to material classification, physical performance, dimensions and workmanship; and the regrind or recycled plastics used have not been subjected to severe environments in post consumer applications (such as chemical service) which could adversely affect the end products performance when subjected to machining or critical applications or both. 1.4 The values are stated in inch-pound units and are regarded as the standard in all property and dimensional tables. For reference purposes, SI units are also included in Table 1 only. 1.5 The following safety hazards caveat pertains only to the test method portions section 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. Note 1: There is no known ISO equivalent to this standard. 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.
