本文件规定了测试样品的制备方法和用于确定聚(亚苯基醚)(PPE)模塑和挤出材料性能的测试方法。给出了处理测试材料的要求以及用于在测试之前调节测试材料和测试之前的样本的要求。 描述了用于制备测试样本的程序和条件,并给出了用于测量制造这些样本的材料的性质的程序。列出了表征聚(亚苯基醚)模塑和挤出材料所需的性能和测试方法。 这些属性已从ISO 10350-1中的通用测试方法中选择。本文件中还包括广泛用于或特别适用于这些模塑和挤出材料的其他测试方法,以及ISO 20557-1中规定的指定性能。 为了获得可再现和可比较的测试结果,打算使用本文档中规定的准备和调节方法,样本尺寸和测试程序。确定的数值不一定与使用不同尺寸或准备的样本获得的值相同使用不同的程序。
This document specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of poly(phenylene ether) (PPE) moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given. Procedures and conditions are described for the preparation of test specimens, 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 poly(phenylene ether) 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 20557‑1. 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.
