标准范围

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:颗粒大小可能大于；300μm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 8130-1中所述的筛分分析或ISO 13322-2中所述的动态图像分析进行验证。

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.
