本文件规定了一种通过激光衍射测定涂层粉末等效球形粒度分布的方法，适用于粒度范围为1µm至300µm的颗粒。 注:粒径>300µm的颗粒可能需要使用不同的光学模型。 本文件专门用于测量涂层粉末，并提请注意ISO 13320，该文件提供了仪器鉴定和粒度分布指南。 激光衍射不适用于测定超大材料，可通过ISO 8130中所述的筛分分析进行验证- 1或ISO 13322-2中所述的动态图像分析。交叉引用:ISO 9276-2ISO 8130-14ISO 9276-1ISO 291ISO 15528ISO 13320ISO 9276-4ISO 13322-2购买本文件时提供的所有现行修订版均包含在购买本文件中。

This document specifies a method for the determination of the equivalent-sphere particle size distribution of coating powders by laser diffraction, for particles of the size range from 1 µm to 300 µm. NOTE There is a possibility that particle sizes >300 µm need the use of a different optical model. This document is specific for the measurement of coating powders and also draws attention to ISO 13320, which provides guidance on instrument qualification and particle size distribution. Laser diffraction is not suitable for determining oversize material, which can be verified by sieve analysis as described in ISO 8130-1 or by dynamic image analysis as described in ISO 13322-2.Cross References:ISO 9276-2ISO 8130-14ISO 9276-1ISO 291ISO 15528ISO 13320ISO 9276-4ISO 13322-2All current amendments available at time of purchase are included with the purchase of this document.
