Revised Standard from Last Update.

1. Scope

This standard [P : 118] test method covers the determination of the total concentration of naphthalene, acenaphthene, and alkylated derivatives of these hydrocarbons in jet fuels containing not more than 5 percent of such components and having end points below 315°C, by ultraviolet spectrophotometry.

NOTE - This test method should not be used to measure and describe the properties of the materials, products or assemblies of molecules other than Aviation Turbine Fuel (ATF) samples, although the scope can be extended on account of precision and repeatability.
