本文件建立了聚酰胺（PA）模塑和挤压材料的命名系统，可作为规范的基础。 聚酰胺塑料的类型通过基于指定特性的适当级别的分类系统相互区分 a） 粘度值， b） 拉伸模量，以及 c） 成核添加剂， 以及关于成分、预期用途和/或加工方法、重要特性、添加剂、着色剂、填料和增强材料的信息。 命名系统适用于所有聚酰胺均聚物、共聚物和共混物。 它适用于可供正常使用的未改性材料和改性材料，例如通过着色剂、添加剂、填料、增强材料和聚合物改性剂进行的材料。 本文件不适用于以下材料: —？PA6单体浇铸型聚酰胺； —？PA12单体浇铸型聚酰胺。 这并不意味着具有相同名称的材料具有相同的性能。本文件不提供指定材料所需的工程数据、性能数据或加工条件数据。如果需要此类附加性能，可根据ISO 16396-2中规定的试验方法确定（如适用）。 为了指定特定应用的热塑性材料，可在数据块5中给出附加要求（见4.1）。

This document establishes a system of designation for polyamide (PA) moulding and extrusion materials, which can be used as the basis for specifications. The types of polyamide plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties a) viscosity number, b) tensile modulus, and c) nucleating additive, and on information about composition, intended application and/or method of processing, important properties, additives, colorants, fillers, and reinforcing materials. The designation system is applicable to all polyamide homopolymers, copolymers, and blends. It is applicable to unmodified materials ready for normal use and materials modified, for example, by colorants, additives, fillers, reinforcing materials, and polymer modifiers. This document does not apply to the following materials: —    monomer casting-type polyamides of PA 6; —    monomer casting-type polyamides of PA 12. It is not intended to imply that materials having the same designation give the same performance. This document does not provide engineering data, performance data, or data on processing conditions which can be required to specify a material. If such additional properties are required, they can be determined according to the test methods specified in ISO 16396-2, if suitable. In order to specify a thermoplastic material for a particular application, additional requirements can be given in data block 5 (see 4.1).
