The fuel industry has relied on ASTM D1319 to quantify the aromatic content of aviation, diesel, and gasoline fuels. In 2018, Honeywell UOP changed the fluorescent indicator dye gel formulation in response to the olefin marker component no longer being available. The DOD conducted a testing program to determine if the prototype dye gel was suitable for testing aviation fuels. Diesel and gasoline fuels were excluded from this study as they are not primary fuels for the DOD. Honeywell UOP provided prototype dye gel from lot 3000000983 to US Army Combat Capabilities Development Command CCDC Ground Vehicle System Center GVSC, Naval Air Systems Command NAVAIR, and Air Force Petroleum Office AFPET laboratories. Twelve aviation jet fuel samples were tested in duplicate ranging in aromatic content from 0-24 percent volume. The Mean Delta across the samples, in all but one case, trends higher in measured aromatic content. Standard deviation indicates that the prototype dye gel is performing similarly to the legacy dye gel for jet fuel. The DOD concluded that the new prototype dye gel performs similarly to the legacy dye gel when testing aviation fuel.
