GSO ASTM D6377:2024 Scope
1.1 This 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 25 kPa and
180 kPa at 37.8 °C at vapor-liquid ratios from 4:1 and 0.02:1
(X = 4 and 0.02).
NOTE 1—This test method is suitable for the determination of the vapor
pressure of crude oils at temperatures from 0 °C to 100 °C and pressures
up to 500 kPa, but the precision and bias statements (see Section 14) may
not be applicable. The current precision of the method is limited at
vapor-liquid ratios of 0.02 and 4. (Section 14 is inclusive of vapor-liquid
ratios of 0.02 and 4).
1.2 This test method also allows the determination of vapor
pressure for crude oil samples having pour points above 15 °C
provided the proper sample handling, transfer, and analysis
procedures are followed.
1.3 The values stated in SI units are to be regarded as
standard. No other units of measurement are included in this
standard.
1.4 This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
For specific warning statements, see 7.2.1 – 7.3.2.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the
Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.
