WATER REACTION OF AVIATION FUELS: ASTM D1094
(Equivalent Test Methods: IP 289, ISO 6250, DIN 51415, and AFNOR M07-050)
TEST SUMMARY
When applied to aviation gasoline, water reaction volume change reveals the presence of water-soluble components such as alcohols. When applied to aviation turbine fuels, water reaction interface rating reveals the presence of relatively large quantities of partially soluble contaminants such as surfactants.
A sample of the fuel is shaken, using a standardized technique, at room temperature with a phosphate buffer solution in scrupulously cleaned glassware. The cleanliness of the glass cylinder is tested. The change in the volume of the aqueous layer and the appearance of the interface are taken as the water reaction of the fuel.
TEST PRECISION
This is a qualitative test, and statements of precision or bias are not appropriate.
