4.4.3.1 Cleaning. Before testing any nozzle, all oil, grease, or any other corrosion-
resistant compound shall be removed from the interior and exterior surfaces.
4.4.3.2 Test fluid. Except as specified herein, all tests shall be conducted using a test
fluid conforming to MIL-T-5624, grade JP-4; MIL-C-7024, type II; MIL-T-83133, grade JP-8
and ASTM D910. The test fluid temperature shall be between +60 and +90°F for type I nozzle
and -60 to +90°F for type II nozzle, with the exception of the fuel resistance test 4.4.4.8 through
low temperature test 4.4.4.9. The test fluid temperature shall be at ambient temperature for the
refueling test 4.4.4.19. All flow rate performance data shall be corrected to a specific gravity of
0.78.
