This method determines the gross calorific value of coal and coke using either a isoperibol (calorimeter where the surrounding jacket is maintained at constant temperature) or adiabatic (variant temperature) bomb calorimeter. content of the quantity of coal or coke represented by the sample for payment purposes.
The gross calorific value can be used for computing the calorific value versus sulfur content to determine whether the coal meets regulatory requirements for industrial fuels, used to evaluate the effectiveness of beneficiation processes, or classify coals according to Classification D 388.
This method replaces ASTM D3286-96.
