ASTM D323 measures this property under specific saturation conditions. Unlike a true thermodynamic vapor pressure, the Reid method involves a specific ratio of liquid volume to vapor volume (usually 1:4). The test measures the total pressure developed by the sample, including air and water vapor present in the apparatus, which is then corrected to give the final RVP value.
