ISO 13322:2004适用于用于确定粒度分布的图像分析。将颗粒适当地分散并固定在光学或电子显微镜样品平台上，例如载玻片、短柱、过滤器等。图像分析可以直接从显微镜或显微照片中恢复颗粒图像。即使分析的自动化是可能的，该技术基本上限于小于一个数量级的窄尺寸分布。对数正态分布的标准偏差为1.6，对应于大小小于10:1的分布。这种窄分布需要测量超过6000个颗粒以获得可重复的体积平均直径。如果需要可靠的百分位数值，例如D90或其他百分位数，则必须测量至少61 000个颗粒。
ISO 13322:2004 is applicable to the analysis of images for the purpose of determining particle size distributions. The particles are appropriately dispersed and fixed on an optical or electron microscope sample stage such as glass slides, stubs, filters, etc. Image analysis can recover particle images directly from microscopes or from photomicrographs.Even though automation of the analysis is possible, this technique is basically limited to narrow size distributions of less than an order of magnitude. A standard deviation of 1,6 of a log-normal distribution corresponds to a distribution of less than 10:1 in size. Such a narrow distribution requires that over 6 000 particles be measured in order to obtain a repeatable volume-mean diameter. If reliable values are required for percentiles, e.g. D90 or other percentiles, at least 61 000 particles must be measured.
