ASTM D4809-13 - International Standards
STANDARD TEST METHOD FOR HEAT OF COMBUSTION OF LIQUID HYDROCARBON FUELS BY BOMB CALORIMETER (PRECISION METHOD). This test method covers the determination of the heat of combustion of hydrocarbon fuels. It is designed specifically for use with aviation turbine fuels when the permissible difference between duplicate determinations is of the order of 0.2%. It can be used for a wide range of volatile and nonvolatile materials where slightly greater differences in precision can be tolerated.
