本文件规定了试样制备方法以及用于测定PS-I模塑和挤出材料性能的试验方法。它规定了处理试验材料的要求，以及模塑前试验材料和试验前试样的调节要求。 本文件给出了制备试样和程序的程序和条件 用于测量制作这些试样的材料的性能。它列出了性能和测试方法是适合和必要的，以表征PS-I模塑和挤出材料。 性能已从ISO 10350-1中的一般试验方法中选择。其他广泛使用或对这些模塑和挤压材料有特殊意义的试验方法也包括在本文件中 文件，如ISO 19063-1中规定的指定属性。 试样制备和处理方法、试样尺寸和本文规定的试验程序用于获得可重复和可比的试验结果。所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 PS-I moulding and extrusion materials. It establishes the requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing. This document gives procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made. It lists properties and test methods which are suitable and necessary to characterize PS-I moulding and extrusion materials. 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 19063-1. The methods of specimen preparation and conditioning, the specimen dimensions and the test procedures specified herein are used to obtain reproducible and comparable test results. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.
