标准摘要
[中文适用范围]： 本文件规定了使用 EDTA 测定铁矿石中总铁含量的光度滴定方法。 该方法适用于天然铁矿石、铁精矿和团矿（包括烧结产品）中总铁质量分数为37.00%至72.00%的浓度范围。 该方法不能作为裁判方法。 [外文原描述]： This document specifies a photometric titration method using EDTA for the determination of the total iron content of iron ores. This method is applicable to a concentration range of a mass fraction of 37,00 % to 72,00 % of total iron in natural iron ores, iron ore concentrates and agglomerates, including sinter products. This method does not apply as a referee method.
