1.1 ,This test method covers the use of manual vapor pressure instruments to determine the vapor pressure of crude oils exerted in a vacuum. This test method is suitable for testing samples that exert a vapor pressure between 25 ,kPa and 180 ,kPa at 37.8 ,°,C at vapor/liquid ratios from 4:1 to 0.25:1 (X = 4 to 0.25, see 3.2.4).
Note 1: ,This test method is suitable for the determination of the vapor pressure of crude oils at temperatures from 0 ,°,C to 60 ,°,C and pressures up to 500 ,kPa, but the precision and bias statements (see Section 15) may not be applicable.
