      Validation indices including sensitivity, recovery accuracy, repeatability, matrix effect, and biological concentrations were compared and evaluated across all methods. The methods were also applied to a comparison of conventional and germ-free mouse feces and further validated by NMR metabolic fingerprinting and bomb by: Under normal conditions, the method is directly applicable to such fuels as gasolines, kerosines, Nos. 1 and 2 fuel oil, Nos. 1-D and 2-D diesel fuel and Nos. 0-GT, 1-GT, and 2-GT gas turbine fuels.

Various test methods for measuring the heat release rate of materials and products under different conditions have therefore been developed. This chapter is dedicated to these test methods. An apparatus used for measuring heat release rate is referred to as a calorimeter and the measurement of heat release rate is called calorimetry.

As stated in the book, a bomb calorimeter is "a more sophisticated version" of a regular calorimeter. The difference between the two is that a regular calorimeter is simply a "thermally insulated container" whereas in a bomb calorimeter, the reaction takes place in a sealed metal container which is immersed in water in an insulated container.

This test method covers the determination of the heat of combustion of liquid hydrocarbon fuels ranging in volatility from that of light distillates to that of residual fuels. Under normal conditions, this test method is directly applicable to such fuels as gasolines, kerosines, Nos.
