SMOKE POINT OF KEROSENE AND AVIATION TURBINE FUEL: D1322
(Equivalent Test Methods: IP 57, ISO 3014, DIN 51406, JIS K 2537, and AFNOR M07-028)
EXPLANATION
The smoke point (and Luminometer number with which it can be correlated) is quantitatively related to the potential radiant heat transfer from the combustion products of the fuel. Because radiant heat transfer exerts a strong influence on the metal temperature of combustor liners and other hot sections of gas turbines, the smoke point provides a basis for correlation of fuel characteristics with the life of these components.
This test method provides an indication of the relative smoke producing properties of kerosene and aviation turbine fuels in a diffusion flame. The smoke point is related to the hydrocarbon type composition of such fuels. Generally the more aromatic the fuel, the smokier the flame. A high smoke point number indicates a fuel of low smoke producing tendency.
TEST SUMMARY
The sample is burned in an enclosed wick-fed lamp that is calibrated daily against pure hydrocarbon blends of known smoke point. The maximum height of flame that can be achieved with the test fuel without smoking is determined to the nearest 0.5 mm.
TEST PRECISION
Repeatability: 2 mm
Reproducibility: 3 mm
This test method has no bias.
