塑料.乙烯-醋酸乙烯酯（EVAC）模塑和挤压材料.第2部分:试样制备和性能测定

[中文适用范围]： 本文件规定了测试样品的制备方法以及用于确定乙烯/醋酸乙烯酯（EVAC）模塑和挤出材料性能的测试方法。 本文件给出了处理测试材料以及成型前测试材料和测试前样品的调节要求。 本文件给出了制备测试样品的程序和条件以及测量制造这些样品的材料性能的程序。 本文件列出了适合且必要的 EVAC 模塑和挤出材料特性和测试方法。 这些特性选自 ISO 10350-1 中的一般测试方法。 本文件还包括广泛使用或对这些模塑和挤出材料特别重要的其他测试方法，以及 ISO 21301-1 中规定的指定性能。 使用本文件规定的制备和调节方法、样本尺寸和测试程序是为了获得可重复和可比较的测试结果。 测定的值不一定与使用不同尺寸的样本获得的值或使用不同程序制备的值相同。 [外文原描述]： 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.
