本文件规定了试样的制备方法以及测定聚苯硫醚（PPS）模塑和挤出材料性能的试验方法。给出了在模塑前处理试验材料和在试验前调节试验材料和试样的要求。描述了制备试样的程序和条件，并给出了制备这些试样的材料的性能测量程序。列出了表征聚苯硫醚模塑和挤出材料的性能和测试方法。性能选自ISO 10350-1中的一般试验方法。与ISO 20558-1（熔体质量流量或熔体粘度、密度和拉伸模量）中规定的指定性能一样，本文件中也包括了广泛用于或对这些模塑和挤压材料特别重要的其他试验方法。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。所确定的数值不一定与使用不同尺寸试样或使用不同程序制备的数值相同。

This document specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of poly(phenylene sulfide) (PPS) 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 sulfide) 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 20558‑1 (melt mass-flow rate or melt viscosity, density and tensile 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.
