This Part of GB/T 6730 specifies the preparation of pre-dried samples for iron ore analysis. This standard applies to natural iron ores, iron concentrates and agglomerates, including the preparation of predried samples for analysis in sintered products. This section does not apply to direct reduced iron samples containing metallic iron, natural or processed iron ore samples containing more than 0.2% (mass fraction) of sulfur or more than 2.5% (mass fraction) of hydrated water, the above samples are used GB/T 6730.3.
