1.1 This test method covers the determination, by ultraviolet spectrophotometry, of the total concentration of naphthalene, acenaphthene, and alkylated derivatives of these hydrocarbons in straight-run jet fuels containing not more than 5 % of such components and having end points below 315°C (600°F). This test method determines the maximum amount of naphthalenes that could be present.
