标准摘要
[中文适用范围]： 该文件建立了聚碳酸酯（PC）模塑和挤出材料的命名系统，可作为规范的基础。 聚碳酸酯塑料的类型通过基于适当级别的指定性能的分类系统来区分： a) 熔体体积流动速率； b)夏比缺口冲击强度；以及有关预期应用和/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。 本文件适用于所有聚碳酸酯均聚物和共聚物。 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。 这并不意味着具有相同名称的材料必然具有相同的性能。 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。 如果需要此类附加属性，则应根据 ISO 21305-2 规定的测试方法（如果适用）进行确定。 为了指定热塑性材料以满足特定规格，数据块 5 中给出了要求（见 4.6）。 [外文原描述]： This document establishes a system of designation for polycarbonate (PC) moulding and extrusion materials, which can be used as the basis for specifications. The types of polycarbonate plastic are differentiated from each other by a classification system based on appropriate levels of the designatory properties: a) melt volume-flow rate; b) Charpy notched impact strength; and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. This document is applicable to all polycarbonate homopolymers and copolymers. It applies to unmodified materials ready for normal use and materials modified, for example, by colorants, additives, fillers, reinforcing materials, and polymer modifiers. It is not intended to imply that materials having the same designation give necessarily 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 are intended to be determined in accordance with the test methods specified ISO 21305-2, if suitable. In order to designate a thermoplastic material to meet particular specifications, the requirements are given in data block 5 (see 4.6).
