Full Description

1.1This test method covers the use of automated vapor pressure instruments to determine the vapor pressure exerted in vacuum of crude oils. This test method is suitable for testing samples that exert a vapor pressure between 25kPa and 180kPa at 37.8C at vapor-liquid ratios from 4:1 to 0.02:1 (X = 4 to 0.02).

Note 1:This test method is suitable for the determination of the vapor pressure of crude oils at temperatures from 0C to 100C and pressures up to 500 kPa, but the precision and bias statements (see Section 14) may not be applicable.

1.2This test method also allows the determination of vapor pressure for crude oil samples having pour points above 15C provided the proper sample handling, transfer, and analysis procedures are followed.

1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 7.2.1 - 7.3.2.
