1.1 该分类系统涵盖适用于成型和挤出的聚酰胺材料。这些组合物中的一些也适用于从溶液中应用。 1.2 本分类系统中包含的财产是识别所涵盖成分所需的属性。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路标注（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。在仔细考虑了零件所需的设计和性能、零件所处的环境、所采用的制造工艺、所涉及的成本以及材料的固有财产（本分类系统所涵盖的除外）后，塑料领域的专业人士可以选择材料。 1.4 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。 1.5 以下注意事项仅适用于第节测试方法部分 11 ，属于该分类系统。 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: 这个分类系统类似于ISO 16396-1/-2, 尽管技术内容明显不同。 注2: 该分类系统涵盖的材料包括聚酰胺的一个子集，定义为聚邻苯二甲酰胺（PPA），如 3.2.1 ，其中一些也在ASTM中进行了分类 第5336页 具体而言，本标准中的第7、10、12、13、14、15和17组为PPA材料。 ASTM公司 第5336页 给出了关于组10、12和13的进一步细节。 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 classification system covers polyamide materials suitable for molding and extrusion. Some of these compositions are also suitable for application from solution. 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 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 classification system. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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: This classification system is similar to ISO 16396-1/-2, although the technical content is significantly different. Note 2: The materials covered by this classification system include a subset of polyamides defined as polyphthalamides (PPA) as in 3.2.1 , some of which are also classified in ASTM D5336 . Specifically, groups 7, 10, 12, 13, 14, 15 and 17 in this standard are PPA materials. ASTM D5336 gives further details relating to groups 10, 12 and 13. 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.
