标准摘要
[中文适用范围]: 本文件规定了测试样品的制备方法以及用于确定热塑性聚酯/酯和聚醚/酯弹性体模塑和挤出材料性能的标准测试方法。 给出了在成型前处理测试材料和/或调节测试材料和测试前样本的要求。 给出了在特定状态下制备测试样品的程序和条件以及测量制备这些样品的材料的性能的程序。 列出了表征热塑性聚酯/酯和聚醚/酯模塑和挤出材料的合适且必要的性能和测试方法。 这些特性选自 ISO 10350-1 中的一般测试方法。 本文件还包括广泛使用或对这些模塑和挤出材料特别重要的其他测试方法,以及 ISO 20029-1 中规定的指定性能(硬度、熔化温度和拉伸/弯曲模量)。 为了获得可重复和可比较的测试结果,打算使用本文件中规定的制备和调节方法、样本尺寸和测试程序。 测定的值不一定与使用不同尺寸的样本获得的值或使用不同程序制备的值相同。 本文件是在 ISO 10350-1 的基础上制定的,因为目前尚无用于获取和呈现热塑性弹性体可比单点数据的标准。 在本文件和聚氨酯类似文件 (ISO 16365-2) 发布后,打算根据本文件和 ISO 16365 制定 ISO 10350-3,用于获取和呈现热塑性弹性体的可比单点数据-2,作为制定热塑性弹性体材料标准的基础。 [外文原描述]: ISO 20029-2:2017 specifies the methods of preparation of test specimens and the standard test methods to be used in determining the properties of thermoplastic polyester/ester and polyether/ester elastomer moulding and extrusion materials. Requirements for handling test material and/or conditioning both the test material before moulding and the specimens before testing are given. Procedures and conditions for the preparation of test specimens in a specified state and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize thermoplastic polyester/ester and polyether/ester moulding and extrusion materials are listed. The properties have been selected from the general test methods in ISO 10350‑1. Other test methods in wide use for or of particular significance to these moulding and extrusion materials are also included in this document, as are the designatory properties specified in ISO 20029‑1 (hardness, melting temperature and tensile/flexural modulus). In order to obtain reproducible and comparable test results, it is intended to use the methods of preparation and conditioning, the specimen dimensions and the test procedures specified in this document. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures. ISO 20029-2:2017 has been developed on the basis of ISO 10350‑1, as at the moment, no standard exists for the acquisition and presentation of comparable single-point data for thermoplastic elastomers. After publication of this document and the analogous document for polyurethanes (ISO 16365‑2), it is the intention to develop ISO 10350‑3 for the acquisition and presentation of comparable single-point data for thermoplastic elastomers, based on this document and ISO 16365‑2, as the basis for the development of thermoplastic-elastomer material standards.
