FIELD: measurement technology.
SUBSTANCE: invention relates to methods for assessment of operational properties of fuels, particularly, to evaluation of antiwear properties of fuel for jet engines, and can be used in petrochemical, aircraft and other industries. Essence: a spherical sample in the form of a ball rigidly fixed in the holder is pressed with constant load to the rotating relative to horizontal axis check sample-truncated cone, immersed into test fuel with preset temperature. Holder is able to freely rotate about vertical axis with periodic snubbing. After the test maximum and minimum diameters of track wear on the surface of the ball are measured and value of wear is calculated. Wear indicator characterizes antiwear properties of fuels.
EFFECT: improving reliable evaluation of antiwear properties of fuel for jet engines by approximation of test conditions to real conditions of gas turbine engine fuel pump plunger pair operation.
