Abstract: The field fast testing methods for import aviation kerosene before being discharged were studied including electrical conductivity, water separation index, flash point, freezing point and fast distillation range, and the validity effect of these methods was analyzed and evaluated. According to the standards of American society for testing and materials, electrical conductivity and water separation index field fast testing could be conducted by instruments; flash point, freezing point and fast distillation range were determined in advance by portable minitype Fourier transform mid-infrared spectroscopy. By these fast methods, the quality pre-judge of import aviation kerosene could be realized, which was very helpful to minimize the risk of disqualification after aviation kerosene being discharged.
