1.1 ,This test method covers the determination of the temperature at which the vapor formed from a selected volume of volatile petroleum product saturated with air at 0 ,°,C to 1 ,°,C (32 ,°,F to 34 ,°,F) produces a pressure of 101.3 ,kPa (one atmosphere) against vacuum. This test method is applicable to samples for which the determined temperature is between 36 ,°,C and 80 ,°,C (97 ,°,F and 176 ,°,F) and the vapor-liquid ratio is between 8 to 1 and 75 to 1.
