本文件建立了聚苯硫醚（PPS）热塑性材料的命名体系，可作为规范的基础。聚苯硫醚（PPS）材料的类型通过一个基于适当等级的设计性能的分类系统来区分a） 熔体质量流量或熔体粘度；b） 密度；c） 拉伸模量；以及有关预期用途和\/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。本文件适用于所有PPS材料。它适用于以粉末、颗粒或颗粒形式准备正常使用的材料，以及未经着色剂、添加剂、填料等改性或改性的材料。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、性能数据或有关加工条件的数据，这些数据可用于指定特定应用和\/或加工方法所需的材料。如果需要此类附加性能，则应根据ISO 20558-2中规定的试验方法（如适用）进行测定。为了指定特定应用的热塑性材料或确保可重复处理，数据块5中给出了要求（见4.1）。

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).
