Laboratory flammability tests and bench-scale ballistic tests are described which have been used in the development of fire-resistant diesel fuel FRF. These tests have indicated that FRF, at a bulk liquid temperature of 77 deg C, would be self extinguishing even if the flash point of its base fuel was less than 62 deg C. In order to confirm that this self-extinguishing property would prove effective in a realistic combat environment, arrangements were made for a series of tests to be conducted. These tests used 3.2-inch precision shaped charges fired through the armor and internally mounted fuel tanks of M48 battle tank and M113 armored personnel carrier hulks. AFLRL personnel participated in the planning and conducting of the tests, including all FRF blending. Results of the full-scale tests confirmed that residual burning can be eliminated by the use of FRF even though the mist fireball development is similar to that of neat fuel. Transient pressure effects are not affected by FRF, but sustained temperatures are drastically reduced by the FRF self-extinguishment.
