Research Report RR:D02-1619
An interlaboratory study was initiated using two vapor pressure methods, ASTM D5191 and D6378. This study established a precision and bias statement for D6378 and evaluated the precision and bias statement for D5191. Finally, this report compared the precision statements of D5191 versus D6378.
D6378-20 Standard Test Method for Determination of Vapor Pressure (VPX) of Petroleum Products, Hydrocarbons, and Hydrocarbon-Oxygenate Mixtures (Triple Expansion Method)
D5191-20 Standard Test Method for Vapor Pressure of Petroleum Products and Liquid Fuels (Mini Method)
