标准摘要
[中文适用范围]: 本文件建立了热塑性聚酯/酯和聚醚/酯弹性体的命名系统,可用作规范的基础。 热塑性聚酯/酯和聚醚/酯弹性体的类型通过基于适当水平的指定性能的分类系统彼此区分: a) 硬度; c) 拉伸/弯曲弹性模量; b) 熔化温度;以及有关预期应用和/或加工方法、重要特性、添加剂、颜色、填料和增强材料的信息。 本文件适用于所有热塑性聚酯/酯和聚醚/酯弹性体。 它适用于正常使用的粉末、颗粒或丸状材料,未经改性或经着色剂、填料或其他添加剂改性。 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。 如果需要此类附加属性,则应根据 ISO 20029-2 中规定的测试方法(如果适用)来确定。 为了指定热塑性聚酯/酯或聚醚/酯弹性体以满足特定规格,数据块 5 中给出了要求(见 4.1)。 [外文原描述]: ISO 20029-1:2017 establishes a system of designation for thermoplastic polyester/ester and polyether/ester elastomers, which may be used as the basis for specifications. The types of thermoplastic polyester/ester and polyether/ester elastomer are differentiated from each other by a classification system based on appropriate levels of the designatory properties: a) hardness; b) melting temperature; c) tensile/flexural modulus of elasticity; and on information about the intended application and/or method of processing, important properties, additives, colour, fillers and reinforcing materials. ISO 20029-1:2017 is applicable to all thermoplastic polyester/ester and polyether/ester elastomers. 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 20029-2, if suitable. In order to designate a thermoplastic polyester/ester or polyether/ester elastomer to meet particular specifications, the requirements are given in data block 5 (see 4.1).
