Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method)

Importancia y uso:

5.1 Vapor pressure is an important physical property of volatile liquids. This test method is used to determine the vapor pressure at 37.8 °C (100 °F) of petroleum products and crude oils with initial boiling point above 0 °C (32 °F).

5.2 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.

5.3 Vapor pressure of crude oils is of importance to the crude producer and the refiner for general handling and initial refinery treatment.

5.4 Vapor pressure is also used as an indirect measure of the evaporation rate of volatile petroleum solvents.
