本文件建立了砜聚合物模塑和挤出材料的名称体系，包括聚砜（PSU）、聚醚砜（PESU）和聚苯砜（PPSU），可作为规范的基础。砜聚合物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） 荷载下的挠度温度，b） 熔体质量流量，c） 夏比缺口冲击强度，d） 拉伸模量，以及e） 屈服应力，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。本文件适用于含有醚氧的所有砜聚合物，醚氧是二苯砜部分中聚合物的必要成分。它适用于未经改性的粉末、颗粒或颗粒形式的供正常使用的砜聚合物材料或用着色剂、添加剂、填料等改性。本文件并不意味着具有相同名称的材料必然具有相同的性能。它不提供工程数据、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。如果需要此类附加性能，则应根据ISO 24025-1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 sulfone polymer moulding and extrusion materials, including polysulfone (PSU), polyethersulfone (PESU) and polyphenylsulfone (PPSU), which can be used as the basis for specifications. The types of sulfone polymer materials are differentiated from each other by a classification system based on appropriate levels of the designatory properties a) temperature of deflection under load, b) melt mass-flow rate, c) Charpy notched impact strength, d) tensile modulus, and e) yield stress, and on information about composition, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. This document is applicable to all sulfone polymers that contain ether oxygen, which is a necessary component of the polymers as in the diphenyl sulfone moiety. It applies to sulfone polymer materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colorants, additives, fillers, etc. This document not intended to imply that materials having the same designation necessarily give the same performance. It 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 determined in accordance with the test methods specified in ISO 24025-1, 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).
