标准摘要
[中文适用范围]: 本文件规定了使用手动 Blaine 透气度仪测定铁矿石比表面积细度的方法。 本文件适用于比表面积在 400 cm2/g 至 2500 cm2/g 范围内的颗粒饲料。 [外文原描述]: ISO 21283:2018 specifies a method to determine the fineness of iron ores in terms of specific surface area, using the manual Blaine air-permeability apparatus. ISO 21283:2018 is applicable to pellet feeds in the range of 400 cm 2 /g to 2 500 cm 2 /g of specific surface area.
英文名称Iron ores — Determination of specific surface area — Test method using air-permeability apparatus (Blaine)
