标准摘要
[中文适用范围]： ：本文件规定了铁矿石中钾质量分数测定的火焰原子吸收光谱法。该方法适用于天然铁矿石、铁矿石 concentrates 和团聚物（包括烧结产品）中 0.0025% 至 0.52% 的钾质量分数。 [外文原描述]： ISO 13312:2017 specifies a flame atomic absorption spectrometric method for the determination of the mass fraction of potassium in iron ores. This method is applicable to mass fractions of potassium between 0,002 5 % and 0,52 % in natural iron ores, iron ore concentrates and agglomerates, including sinter products.
