标准摘要
[中文适用范围]: 本文件详细说明了通过获取和评估扫描电子显微镜图像以及获得和报告准确结果来确定纳米颗粒尺寸和形状分布的方法。 注 1:本文件适用于具有较低尺寸限制的颗粒,该尺寸限制取决于所需的不确定性和 SEM 的合适性能,这将首先根据本文件中描述的要求进行证明。 注 2:本文件也适用于大于纳米级颗粒的基于 SEM 的尺寸和形状测量。 [外文原描述]: This document specifies methods of determining nanoparticle size and shape distributions by acquiring and evaluating scanning electron microscope images and by obtaining and reporting accurate results. NOTE 1 This document applies to particles with a lower size limit that depends on the required uncertainty and on the suitable performance of the SEM, which is to be proven first -according to the requirements described in this document. NOTE 2 This document applies also to SEM-based size and shape measurements of larger than nanoscale particles.
