Reid vapor pressure (RVP) is a common measure of the volatility of gasoline and other petroleum products. It is defined as the vapor pressure exerted by the vapor of the liquid and any dissolved gases/moisture at 37.8 °C (100 °F) as determined by the test method ASTM-D-323, which was first developed in 1930 and has been revised several times (the latest version is ASTM D323-15a).
