ISO 11536:2015规定了一种重量分析法，用于测定在1000°C下点燃时完全氧化铁矿石的质量损失。 本方法适用于天然铁矿石、铁精矿和团块中1,0%（m/m）至10,0%（m/m）的浓度范围内的着火损失。 该方法不适用于以下情况: a） 含金属铁的加工矿石（直接还原铁）； b） 硫含量高于0.2%（m/m）的天然或加工矿石； c） 部分氧化铁含量超过1.0%（m/m）的天然或加工矿石。

ISO 11536:2015 specifies a gravimetric method for the determination of the loss in mass of fully-oxidized iron ores, when ignited at 1 000 °C. This method is applicable to a concentration range of 1,0 % (m/m) to 10,0 % (m/m) loss on ignition in natural iron ores, iron ore concentrates and agglomerates. 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 0,2 % (m/m); c) Natural or processed ores in which the content of partially-oxidized iron is more than 1,0 % (m/m).
