本文件建立了聚醚醚酮（PEEK）模塑和挤出材料的名称体系，可作为规范的基础。聚醚醚酮聚合物链是由两个醚基和一个酮基的序列在（1，4）位置连接的苯环组成。PEEK塑料的等级通过基于适当等级的设计性能的分类系统进行区分a） 熔体粘度或熔体体积流量；b） 拉伸模量；c） 抗拉强度；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。该命名体系适用于所有聚醚酮。适用于未经着色剂、填料、增强剂或其他添加剂改性或改性的粉末、颗粒或颗粒形式的可供正常使用的材料。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 23153-2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中给出了附加要求（见4.1）。

This document establishes a system of designation for polyetheretherketone (PEEK) moulding and extrusion materials which can be used as the basis for specifications. Polyetheretherketone polymer chains are composed of phenylene rings linked in (1,4) position by a sequence of two ether groups followed by one ketone group. The grades of PEEK plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties a) melt viscosity or melt volume-flow rate; b) tensile modulus; c) tensile strength; and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. The designation system is applicable to all polyetheretherketones. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colourants, fillers, reinforcements or other additives. It is not intended to imply that materials having the same designation necessarily 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 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 23153-2, if suitable. In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements are given in data block 5 (see 4.1).
