HK-0794 Automatic Vapor Pressure of Petroleum Products (Mini Method)

Oveview

    HK-0794 Automatic Vapor Pressure of Petroleum Products (Mini Method) conforms to ASTM D5191 Standard Test Method for Vapor Pressure of Petroleum Products (Mini Method).It covers the use of automated vapor pressure instruments to determine the total vapor pressure exerted in vacuum by air-containing,volatile,liquid petroleum products and liquid fuels,including automotive spark-ignition fuels with or without oxygenates and with ethanol blends up to 85 (volume fraction).This test method is suitable for testing samples with boiling points above 0℃ (30℉) that exert a vapor pressure between 7 kPa and 130 kPa(1.0 psi and 18.6 psi) at 37.8 ℃ (100 ℉) at a vapor-to-liquid ratio of 4:1.Measurements are made on liquid sample sizes in the range from 1 mL to 10 mL.No account is made for dissolved water in the sample.
