Over deze norm
ISO/TR 18230 describes a gravimetric method for the determination of the loss in mass of nonoxidized iron ores, when ignited at 1 000 °C. This method is applicable to a concentration range of a mass fraction of -3,0 % to 7,0 % loss on ignition in natural iron ores, iron ore concentrates and agglomerates, and sinters. The method is not applicable to the following: a) processed ores containing metallic iron (direct reduced iron); b) natural or processed ores in which the sulfur content is higher than a mass fraction of 0,2 %; c) internationally traded ores with combined water greater than 2,5 %.
