标准摘要
[中文适用范围]： 该文件建立了聚酰胺（PA）模塑和挤出材料的命名系统，可作为规范的基础。 聚酰胺塑料的类型通过分类系统相互区分，该分类系统基于适当的指定性能水平：a) 粘度值、b) 拉伸模量和 c) 成核添加剂，以及有关成分、预期应用和/或方法的信息加工、重要性能、添加剂、着色剂、填料和增强材料。 该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改性的材料。 本文件不适用于以下材料： ——PA 6 单体浇铸型聚酰胺； ——PA 12 的单体浇铸型聚酰胺。 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，如果合适，可以根据 ISO 16396-2 中规定的测试方法来确定。 为了指定特定应用的热塑性材料，可以在数据块 5 中给出附加要求（见 4.1）。 [外文原描述]： 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).
