1.1本指南涵盖了通过光学和电子显微镜制备用于微观结构检查的塑料和聚合物试样的推荐程序和指南。 1.2本指南适用于大多数半刚性和刚性塑料，包括工程塑料。本指南也适用于一些非刚性塑料。 1.3本指南中介绍的程序和指南通常是产生满意样本的程序和指南。本指南不描述解决个别问题所需的各种技术。 1.4有许多关于塑料和聚合物研磨和抛光的详细说明（1-7）。 1.5本标准无意解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This guide covers recommended procedures and guidelines for the preparation of plastic and polymeric specimens for microstructural examination by light and electron microscopy. 1.2 This guide is applicable to most semi-rigid and rigid plastics, including engineering plastics. This guide is also applicable to some non-rigid plastics. 1.3 The procedures and guidelines presented in this guide are those which generally produce satisfactory specimens. This guide does not describe the variations in techniques required to solve individual problems. 1.4 Many detailed descriptions of grinding and polishing of plastics and polymers are available (1-7). 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
