标准摘要
[中文适用范围]： 该文件规定了一种火焰原子吸收光谱法，用于测定铁矿石中铁矿中钠的质量分数。该方法适用于天然铁矿石、铁矿石精矿和烧结产品（包括烧结矿）中钠质量分数在0.0025%至0.50%范围内的测定。 [外文原描述]： ISO 13313:2017 specifies a flame atomic absorption spectrometric method for the determination of the mass fraction of sodium in iron ores. This method is applicable to mass fractions of sodium between 0,002 5 % and 0,50 % in natural iron ores, iron ore concentrates and agglomerates, including sinter products.
