Application Summary AI generated
This standard specifies a method for determining the relative degree of oxidation in bituminous coal, based on changes in its alkali-soluble humic acid content. It is applied in the coal mining and processing industries to assess the weathering or oxidation level of coal samples, which is critical for evaluating coal quality, storage stability, and combustion performance. The method is used in laboratory testing contexts to guide decisions on coal utilization and handling.
