ASTM D323 - Vapor Pressure of Petroleum Products (Reid Method) (RVP)

We perform quality testing by ASTM D323 to determine the Reid vapor pressure of gasoline, volatile crude oil, and other volatile petroleum products. We can also perform ASTM D5191 - Vapor Pressure Test, which is the more commonly used vapor pressure test method. Vapor Pressure by ASTM D5191 can be performed more quickly and has better repeatability (consistency in test results). Vapor pressure is an important physical property of volatile liquids. Vapor pressure is critically important for both automotive and aviation gasolines, affecting starting, warm-up, and tendency to vapor lock with high operating temperatures or high altitudes. Maximum vapor pressure limits for gasoline are legally mandated in some areas as a measure of air pollution control. Vapor pressure of crude oils is important to crude producers and refiners for general handling and initial refinery treatment. Vapor pressure is also used as an indirect measure of the evaporation rate of volatile petroleum solvents.

We also perform vapor pressure testing by ASTM D2879ASTM D5191ASTM D6377, and ASTM E1782. These different test methods use different instruments or procedures or are used for certain sample types. Click on the test method number to learn more about each test.
