标准摘要
[中文适用范围]： 本国际标准规定了一种使用二安替比林甲烷进行分光光度法测定铁矿石中钛的质量分数。该方法适用于天然铁矿石、铁矿石精矿和烧结矿（包括烧结产品）中钛质量分数为 0,02% 至 4,0% 的范围。 [外文原描述]： ISO 4691:2009 specifies a spectrophotometric method using diantipyrylmethane for the determination of the mass fraction of titanium in iron ores. ISO 4691:2009 is applicable to a mass-fraction range of 0,02 % to 4,0 % of titanium in natural iron ores, and iron ore concentrates and agglomerates including sinter products.
