BS EN ISO 20029-2:2018规定了试样的制备方法以及用于测定热塑性聚酯/酯和聚醚/酯弹性体模塑和挤出材料性能的标准试验方法。给出了处理试验材料和/或在成型前调节试验材料和试验前调节试样的要求。给出了在规定状态下制备试样的程序和条件，以及制备这些试样的材料的性能测量程序。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和必要的性能和试验方法。这些性能是从ISO 10350-1中的通用试验方法中选择的。本文件还包括广泛使用的或对这些模塑和挤压材料具有特殊意义的其他试验方法，以及ISO 20029中规定的设计性能- 1（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试验结果，拟采用本文件中规定的制备和调节方法、试样尺寸和试验程序。确定的值不一定与使用不同尺寸的试样或使用不同程序制备的试样获得的值相同。本文件是在ISO 10350-1的基础上编制的，目前还没有热塑性弹性体可比单点数据的获取和呈现标准。本文件和聚氨酯类似文件（ISO 16365-2）出版后，打算根据本文件和ISO 16365-2制定ISO 10350-3，以获取和展示热塑性弹性体的可比单点数据，作为热塑性弹性体开发的基础- 标准弹性体材料。参考参考参考:ISO 11357-3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 ISO ISO 3 3 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 ISO 3 3 3 3 3 3 3 3 3 3 3 3 3 3 6 6 ISO 6 6 9 9 9 9 9 9 7 7 7 7 7 7 7 1 ISO 4 4 4 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 1 1 1 1 1 1 1 1 1 1 1 1 1 1 ISO 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 9 9 9 9 9 9 9 9 9 ISO-3ISO 1133-2ISO 527-2ISO 8256ISO 37ISO 3167ISO 527-1ISO 10350-1ISO16365-2购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS EN ISO 20029-2:2018 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.This document 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.Cross References:ISO 11357-3ISO 22007-3ISO 75-2IEC 60250ISO 306ISO 899-1ISO 34-1:2015ISO 11359-2:1999ISO 178IEC 60093IEC 60695-11-10ISO 974IEC 60243-1ISO 1183-1ISO 294-1ISO 294-4ISO 62ISO 179-2ISO 868ISO 22007-2ASTM E96ISO 1183-2ISO 815-1ISO 15512ISO 11357-4ISO 20029-1IEC 60112ISO 22007-4ISO 20753ISO 4589-2ISO 179-1ISO 1183-3ISO 1133-2ISO 527-2ISO 8256ISO 37ISO 3167ISO 527-1ISO 10350-1ISO 16365-2All current amendments available at time of purchase are included with the purchase of this document.
