Flash point is one of the major physical and chemical properties used to determine the fire and explosion hazards of liquids; therefore, the prediction of flash point is an important safety consideration. However, the study on flash point and the correlation between flash point and pressure has been inadequate, and needs further investigation. So in this paper, the experimental method is adopted to study the correlation between the closed flash point temperature of RP-5 Aviation Kerosene and low pressure environment. In the experiments, use the BS-1 closed bomb apparatus to measure the oil samples and use the hypobaric chamber to change the environment pressure from 50kPa to 101.3kPa. Through the experiment data, it indicates that the atmospheric pressure is much lower than the normal atmosphere, there is a quadratic function relation between the reciprocal Aviation Kerosene's flash points and logarithm of environment pressure, therefore the relationship between the reciprocal Aviation Kerosene’s flash points and altitude is reciprocal. Compared the experiment results with theoretical results, it finds that the experiment result is closed to reality. The experiment results will provide the scientific data for the safety of aircraft tank, and benefit the fire protection, such as inflammable liquid production, transport, storage et al in oil pipeline management.
