标准摘要
[中文适用范围]： 该文件建立了聚苯硫醚（PPS）热塑性材料的命名系统，可作为规范的基础。 聚苯硫醚 (PPS) 材料的类型通过基于指定性能的适当水平的分类系统彼此区分：a) 熔体质量流动速率或熔体粘度； c) 拉伸模量； b) 密度；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 PPS 材料。 它适用于正常使用的粉末、颗粒或丸粒形式的材料，以及未经改性或经着色剂、添加剂、填料等改性的材料。 这并不意味着具有相同名称的材料必然具有相同的性能。 本文件不提供工程数据、性能数据或加工条件数据，这些数据可能需要为特定应用和/或加工方法指定材料。 如果需要此类附加属性，则应根据 ISO 20558-2 中规定的测试方法（如果适用）来确定。 为了指定特定应用的热塑性材料或确保可重复加工，数据块 5 中给出了要求（见 4.1）。 [外文原描述]： This document establishes a system of designation for poly(phenylene sulfide) (PPS) thermoplastic materials, which can be used as the basis for specifications. The types of poly(phenylene sulfide) (PPS) materials are differentiated from each other by a classification system based on appropriate levels of the designatory properties a) melt mass-flow rate or melt viscosity; b) density; c) tensile modulus; 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 PPS materials. It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc. 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 for a particular application and/or method of processing. If such additional properties are required, they are intended to be determined in accordance with the test methods specified in ISO 20558‑2, if suitable. In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, the requirements are given in data block 5 (see 4.1).
