This information report covers two distinct projects to formulate Jet Refrence Fluids (JRF) for testing of material compatibility. The first effort began in 1978 and focused on producing a formulation (JRF-2) that simulated JP-4 and included composition with metallic ions that reproduced chalking of fuel tank sealants. This effort resulted in the preparation of AMS2629 that defined the formulation of JRF-2 (Type 1) and the same formulation with metallic ions (Type 2). The second effort began in 2002 and focused on preparing a JRF that simulated Jet A, JP-5 and JP-8. This effort went through multiple iterations, but eventually resulted in a JRF-3 formulation composed of Jet A plus military additives spiked to 25% aromatic content and high levels of sulfur experienced in the global fuel supply. Since the metallic ions added to JRF-2 demonstrated their ability to simulate a chalking reaction, chalking was not tested with the ions added to JRF-3. AMS2629 was changed multiple times to reflect the onging changes of this project and included both Type 1 and Type 2 formulations. Modify this AIR to include the efforts of the JRF Subcommittee of SAE G-9 to develop the new Jet Reference Fuel (JRF-3) identified in AMS2629E. JRF-3 more closely represents current JP-5 and JP-8 fuels and was designed to provide a reference fuel for a wider variety of fuel system materials than currently use AMS2629.
