Application Summary AI generated
This standard specifies the classification of coal based on its sulfur content, defining grades such as low-sulfur, medium-sulfur, and high-sulfur coal. It is applied in the coal mining, processing, and trading industries to guide quality assessment, pricing, and environmental compliance for coal used in power generation, metallurgy, and chemical production. The standard also supports testing laboratories in evaluating sulfur levels to control emissions and optimize industrial fuel selection.
