1.1 本规范涵盖了由聚醚酰亚胺（PEI）树脂制造的挤出和压缩模塑板、板、棒和管状棒的尺寸、工艺和性能的要求和测试方法。 1.2 本规范中包含的特性是所涵盖组合物所需的特性。可能需要其他要求来确定对专业应用程序重要的特定特性。应使用第节中给出的后缀对其进行规定 5. . 1.3 本规范不允许使用再生塑料（定义见指南 D7209 ). 1.4 在所有特性和尺寸表中，以英制单位表示的值视为标准值。出于参考目的，国际单位制也包括在 表1 表S-PEI。 1.5 以下安全危险警告仅适用于本规范中描述的一种或多种测试方法。 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。 注1: 没有已知的ISO等效于本标准。 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 the dimensions, workmanship, and the properties of extruded and compression-molded sheet, plate, rod and tubular bar manufactured from polyetherimide (PEI) resins. 1.2 The properties included in this specification are those required for the compositions covered. It is possible that other requirements will be necessary to identify particular characteristics important to specialized applications. These shall be specified by using the suffixes as given in Section 5 . 1.3 This specification does not allow for the use of recycled plastics (as defined in Guide D7209 ). 1.4 The values stated in English units are regarded as standard in all property and dimensional tables. For reference purposes, SI units are also included in Table 1 and Table S-PEI. 1.5 The following safety hazards caveat pertains only to the test method or test methods described in 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.
