本文件建立了聚酮（PK）模塑和挤压材料的命名体系，可作为规范的基础。聚酮聚合物链是由规则交替的烯烃单元和酮基组成的。烯烃单元应为乙烯和丙烯的随机分布单元。聚酮塑料的类型根据设计性能、熔化温度、熔体质量流量、负载下偏转温度的适当水平以及有关预期应用和\/或加工方法、重要性能、添加剂的信息，通过分类系统进行区分，颜色、填料和增强材料。该命名体系适用于所有聚酮三元共聚物和共混物。适用于未经着色剂、填料或其他添加剂改性或改性的粉末、颗粒或颗粒形式的正常使用材料。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可能需要的工程数据、性能数据或加工条件数据。如果需要此类附加性能，则应根据ISO 21970-2中规定的试验方法（如适用）进行测定。为了指定聚酮满足特定规范，数据块5中给出了要求（见4.1）。

This document establishes a system of designation for polyketone (PK) moulding and extrusion materials which may be used as the basis for specifications. Polyketone polymer chains are built up from regularly alternating olefinic units and keto groups. The olefinic units shall be randomly distributed ethylene and propylene. The types of polyketone plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties, melting temperature, melt mass-flow rate, temperature of deflection under load and on information about the intended application and/or method of processing, important properties, additives, colour, fillers and reinforcing materials. The designation system is applicable to all polyketone terpolymers and blends. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colourants, fillers or other additives. 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 may 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 in ISO 21970-2, if suitable. In order to designate a polyketone to meet particular specifications, the requirements are to be given in data block 5 (see 4.1).
