标准范围

ISO 4689-3:2004规定了使用高频感应炉测定铁矿石硫含量的燃烧/红外法。本方法适用于天然铁矿石、铁精矿和烧结矿（包括烧结矿产品）中硫含量在0002%（质量分数）和0.25%（质量分数）之间的情况。该方法不适用于混合水含量超过1.0%（质量分数）的铁矿石。该设备的金属过滤器配有加热装置，可用于混合水含量低于3.0%（质量分数）的铁矿石。

ISO 4689-3:2004 specifies a combustion/infrared method, using a high-frequency induction furnace, for the determination of the sulfur content of iron ores.This method is applicable to sulfur contents between 0,002 % (mass fraction) and 0,25 % (mass fraction) in natural iron ores, iron ore concentrates and agglomerates, including sinter products. The method is not applicable to iron ores containing more than 1,0 % (mass fraction) of combined water. The apparatus, of which the metal filter is equipped with a heating device, can be applied to iron ores containing less than 3,0 % (mass fraction) of combined water.
