Test guideline
- Qualifier:

- Guideline:
- other: ASTM D6378-2010 Standard Test Method for Determination of Vapor Pressure (VPX) of Petroleum Products, Hydrocarbons, and Hydrocarbon-Oxygenate Mixtures (Triple Expansion Method)
- Principles of method if other than guideline:
- Employing the apparatus, MINIVAP VPXpert Vapor Pressure Tester, a certain volume of the sample is drawn into the temperature controlled chamber with a built-in piston. After sealing the chamber, an expansion is performed in three steps to a final volume of (X+1) times that of the test specimen. After each expansion, the total pressure (TPx) is determined. The partial pressure from dissolved air (PPA) and the solubility of air in the specimen can be calculated from the three resulting pressures. The temperature of the chamber is then increased to a specified value, and the TPx is determined. The vapor pressure (VPx) can be obtained by sub- tracting the PPA in the liquid, which has been gas corrected for the temperature, from TPx.
