GB/T 218-1996
AbolishedDetermination of carbon dioxide content in the mineral carbonates associated with coal
煤中碳酸盐二氧化碳含量的测定方法
Application Summary AI generated
This standard specifies a method for determining the carbon dioxide content released from mineral carbonates (such as calcite and dolomite) present in coal samples. It is applied in the coal mining and quality inspection industries to assess the inorganic carbon content, which is critical for accurate coal classification, combustion calculations, and environmental emission evaluations. The test is typically conducted in laboratories during coal resource assessment or before industrial utilization.
