1.1 该分类系统涵盖适用于注塑和挤出的未填充、填充和增强的聚醚酰亚胺材料。 1.2 该分类系统中包含的特性是识别所涵盖成分所需的特性。通过使用第节中给出的后缀来指定识别对专业应用重要的特定特性所需的其他要求 5. . 1.3 该分类系统和随后的线形标注（规范）旨在提供一种标注最终产品或零件制造中使用的塑料材料的方法。它不用于材料的选择。只有在仔细考虑零件所需的设计和性能、暴露的环境、所采用的制造工艺、所涉及的成本以及本标准所涵盖的材料以外的材料固有特性后，具有塑料领域专业知识的人员才能进行材料选择。 1.4 该分类系统允许使用回收的聚醚酰亚胺材料，前提是满足所有规范要求。 1.5 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 注1: 目前还没有与该标准等效的ISO。 1.6 以下注意事项仅适用于试验方法部分，第节 11 ，属于该分类系统: 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。 的末尾给出了具体的预防说明 5.4 . 1.7 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 classification system covers unfilled, filled, and reinforced polyetherimide materials suitable for injection molding and extrusion. 1.2 The properties included in this classification system are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are to be specified by using suffixes as given in Section 5 . 1.3 This classification system and subsequent line callout (specification) are intended to provide a means of calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection can be made by those having expertise in the plastic field only after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered by this standard. 1.4 This classification system allows for the use of recycled polyetherimide materials, provided that all specification requirements are met. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. Note 1: There is no known ISO equivalent to this standard. 1.6 The following precautionary caveat pertains only to the test methods portion, Section 11 , of this classification system: 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. Specific precautionary statements are given at the end of 5.4 . 1.7 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.
