At the same time it is also used to assess the fire and explosion hazards of liquid fuels. The determination of flash point temperature has a practical meaning in the storage, transport and used of liquid nowaday. Thus we choose the best calculation method to get the result with the lowest averange absolute error (A.A.E) for experiment. Key words: Pensky – Martens, pure liquid, flash point, flammable liquid.

INTRODUCTION Flash point is a major property used to identify the fire hazard of liquids in the safe practice of handling and storing liquid mixtures and to assess the exact level of risk. It is defined as the minimum temperature that vapor appears on the liquid in equilibrium to form a flammable mixture when mixed with air. Flash point is a pure liquid that can be determined by experimental or estimated method by calculating with available information. The information needed for the composite flash point prediction is the vapor pressure and boiling temperature
