本文件规定了试样的制备方法，以及用于测定PVC-P模塑和挤出材料性能的试验方法。它给出了处理试验材料的要求，以及成型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的程序和条件，以及测量制备试样所用材料性能的程序。它列出了表征PVC-P模塑和挤出材料的合适和必要的性能和测试方法。 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 24023（所有零件）中规定的设计特性。

This document specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of PVC-P moulding and extrusion materials. It gives the requirements for handling test materials 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 PVC-P 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 24023 (all parts).
