Application Summary AI generated
This standard specifies the microscopic method for measuring the reflectance of vitrinite, a key maceral in coal. It is applied in the coal mining and processing industries to determine coal rank, assess coal quality, and guide coal blending for metallurgical coke production. The method is also used in geological exploration for evaluating coal seam maturity and thermal history.
