OXIDATION STABILITY OF AVIATION FUELS: ASTM D873
(Equivalent Test Methods: IP 138 and AFNOR M07-013)
EXPLANATION
This test method covers the determination of the tendency of the aviation reciprocating, turbine, and jet engine fuels to form gum and deposits under accelerated aging conditions. The tendency of the fuels to form gum and deposits in these tests has not been correlated with field performance (and can vary markedly) with the formation of gum and deposits under different storage conditions. This test method is not intended for determining the stability of fuel components, particularly those with a high percentage of low boiling unsaturated compounds, as they may cause explosive conditions within the apparatus.
TEST SUMMARY
The fuel is oxidized under prescribed conditions in a pressure vessel filled with oxygen. The amounts of soluble gum, insoluble gum, and precipitates are weighed.
TEST PRECISION
The bias of this test method has not been determined.
