发布日期：2015-08
标准范围
This part of ISO 4689 specifies a combustion/infrared method, using a high-frequency inductionfurnace, 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 % (massfraction) in natural iron ores, iron ore concentrates and agglomerates, including sinter products. Themethod 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 orescontaining less than 3,0 % (mass fraction) of combined water.
