HEAT OF COMBUSTION NET AND GROSS HEAT OF COMBUSTION OF BURNER AND DIESEL FUELS:
HEAT OF COMBUSTION NET AND GROSS HEAT OF COMBUSTION OF BURNER AND DIESEL FUELS: ASTM D4868Similar to the three test methods for aviation fuels, this is also an empirical test based on the correlation between heat of combustion and density, sulfur, water, and ash content of the fuel sample. The test is ...

HEAT OF COMBUSTION OF AVIATION FUELS: ASTM D6446
HEAT OF COMBUSTION OF AVIATION FUELS: ASTM D6446EXPLANATIONThe net heat of combustion is a factor in the performance of all aviation fuels. For high performance weight-limited aircraft, the net heat of combustion per unit mass and the mass of fuel loaded determine the total safe range. The proper operation ...

HEAT OF COMBUSTION OF AVIATION FUELS: ASTM D3338
HEAT OF COMBUSTION OF AVIATION FUELS: ASTM D3338Similar to Test Method ASTM D1405, this is a purely empirical test based on correlation between the net heat of combustion and gravity, aromatic content, and the average volatility of the fuel. Correction for sulfur content of the fuel must be done.This ...

GRAVITY, API BY HYDROMETER METHOD: ASTM D287
GRAVITY, API BY HYDROMETER METHOD: ASTM D287EXPLANATIONAccurate determination of the gravity of petroleum and its products is necessary for the conversion of measured volumes to volumes at the standard temperature of 60° F (15.56° C). Gravity is a factor governing the quality of crude oils. However, ...
