标准编号：ISO 4497:2020

中文名称：金属粉末 用干燥筛分法测定粒度

英文名称：Metallic powders — Determination of particle size by dry sieving

发布日期：2020-04

标准范围

本文件规定了一种通过干法筛分为粒级来确定金属粉末粒度分布的方法。该方法适用于干燥、无润滑的金属粉末，但不适用于形态明显不同于等轴的粉末，例如片状粉末。该方法不适用于粒度全部或大部分小于45μm的金属粉末。

This document specifies a method of determining the particle size distribution of metallic powders by dry sieving into size fractions.The method is applicable to dry, unlubricated metallic powders, but not applicable to powders in which the morphology differs markedly from being equiaxial, for example flake-type powders.The method is not applicable to metallic powders having a particle size wholly or mostly under 45 μm.
