ActiveDetermination of the relative degree of oxidation in bituminous coal
烟煤相对氧化度测定方法
Application Summary AI generated
This standard specifies a method for determining the relative degree of oxidation in bituminous coal by measuring changes in its chemical properties, such as humic acid content. It is applied in the coal mining and processing industries to assess coal quality degradation during storage, transport, or weathering, helping to evaluate combustion efficiency and spontaneous combustion risk. The method is used in laboratory testing contexts for quality control and safety analysis of coal products.
