标准范围

本文件规定了试样的制备方法，以及用于测定乙烯/醋酸乙烯酯（EVAC）模塑和挤出材料性能的试验方法。本文件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。本文件列出了表征EVAC模塑和挤压材料的合适和必要的性能和试验方法。这些性能是从ISO 10350中的通用测试方法中选择的-1.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 21301-1中规定的设计性能。采用本文件规定的制备和调节方法、试样尺寸和试验程序，以获得可重复和可比的试验结果。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。

This document specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of ethylene/vinyl acetate (EVAC) 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 in this document.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. Properties and test methods which are suitable and necessary to characterize EVAC moulding and extrusion materials are listed in this document.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 21301-1.The methods of preparation and conditioning, the specimen dimensions and the test procedures specified this document are used in order 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.
