ASTM D1840

Naphthalene Hydrocarbons in Aviation Turbine Fuels by UV Spectrometry

This test method is used to assess combustion characteristics of aviation turbine fuels of the kerosene boiling range. The naphthalene hydrocarbon content is determined because naphthalenes tend to have a relatively larger contribution to a sooty flame, smoke, and thermal radiation when they are burned. The test method is done via ultraviolet spectrophotometry. It covers the determination of the total concentration of naphthalene, acenaphthene, and alkylated derivatives of these hydrocarbons in jet fuels. This method also determines the maximum amount of naphthalenes that could be present.
