标准摘要
[中文适用范围]： 本文件规定了通过激光衍射测定涂料粉末的当量球粒度分布的方法，颗粒尺寸范围为 1 µm 至 300 µm。 注意 颗粒尺寸 >300 µm 可能需要使用不同的光学模型。 本文件专门针对涂料粉末的测量，还提请注意激光衍射不适用于确定尺寸过大的材料，这可以通过 ISO 8130-1 中所述的筛分分析或 ISO 13322- 中所述的动态图像分析来验证。 2. [外文原描述]： 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.
