Scope

This Standard specifies the principle, test conditions, reagents and materials,
instruments and devices, determination steps, calculation of determination
result, thermal capacity, instrument constant calibration and method precision
for oxygen bomb calorimetric method that is used to determine the gross
calorific value of coal. This Standard also specifies the calculation method for
net calorific value.
This Standard is applicable to solid fossil fuels such as peat, lignite, bituminous
coal, anthracite, coke, carbon shale, and coal water slurry.
