Vapor Pressure Test Method:
The main standard methods for vapor pressure determination are the tertiary expansion method, the micro method, and the Reid method.
1. Petroleum products as well as chemical reagents can be tested for vapor pressure by the tertiary expansion method. The method refers to standards such as SH/T 0769, SN/T 2932 and ASTM D6378 (this standard applies to the determination of temperature 0 ºC ~ 100 ºC, the gas-liquid ratio of 4:1 ~ 0.02:1, the vapor pressure is not higher than 500kPa volatile liquid chemicals vapor pressure determination).
2. The vapor pressure of petroleum products can also be measured by the trace method. The method refers to ASTM D5191 and SH/T 0794 (this standard applies to the boiling point higher than 0 ºC, and in 37.8 ºC, gas-liquid ratio of 4:1 conditions under the vapor pressure of 7kPa ~ 130kPa of liquid petroleum products, and the sample size required in 1ml ~ 10ml)
3. The Reid method is also often used for the testing of vapor pressure of petroleum products. The method refers to GB/T 8017, ASTM D323 and other standards.
