1.1 该分类系统涵盖适用于注塑和挤出的聚酰胺酰亚胺材料。 1.2 该分类系统中包含的属性是识别所涵盖成分所需的属性。可能需要其他要求来确定对专用应用程序重要的特定特性。后缀的使用如第节所示 5. 是指定这些要求的一种方式。 1.3 本标准允许使用回收材料，前提是满足基于该分类系统的规范要求。 1.4 该分类系统和随后的生产线调用（规范）旨在用于调用最终产品或零件制造中使用的塑料材料。 它不用于选择材料。材料选择需要由在塑料领域具有专业知识的人员在仔细考虑零件的设计和性能要求、零件所处的环境、所采用的制造工艺、材料的固有特性（本分类所涵盖的特性除外）以及经济性后进行。 1.5 以国际单位制表示的数值应视为标准。（可以接受英寸磅单位报告。） 1.6 以下预防性警告仅适用于测试方法部分，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。 注1: 没有已知的ISO等同于本标准。 1.7 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。

1.1 This classification system covers polyamide-imide materials suitable for injection molding and extrusion. 1.2 The properties included in this classification system are those required to identify the compositions covered. It is possible that other requirements are necessary to identify particular characteristics important to specialized applications. The use of suffixes as shown in Section 5 is one way of specifying these requirements. 1.3 This standard allows for the use of recycled materials provided that specification requirements based upon this classification system are met. 1.4 This classification system and subsequent line call-out (specification) is intended to be a means of calling out plastics materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection needs to be made by those having expertise in the plastics field 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 inherent properties of the material other than those covered by this classification, and the economics. 1.5 The values stated in SI units are to be regarded as the standard. (Reporting in inch-pound units is acceptable.) 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. Note 1: There is no known ISO equivalent to this standard. 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.
