ASTM D6378-08

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

1. Scope*
1.1 This test method covers the use of automated vapor pressure instruments to determine the vapor pressure exerted in vacuum
by volatile, liquid petroleum products, hydrocarbons, and hydrocarbon-oxygenate mixtures.This test method is suitable for testing
sampleswithboilingpointsabove0°C(32°F)thatexertavaporpressurebetween7and150kPa(1.0and21psi)at37.8°C(100°F)
at a vapor-to-liquid ratio of 4:1. The liquid sample volume size required for analysis is dependent upon the vapor-to-liquid ratio
chosen (see Note 1) and the measuring chamber volume capacity of the instrument (see 6.1.1 and Note 3).
NOTE 1—The test method is suitable for the determination of the vapor pressure of volatile, liquid petroleum products at temperatures from 0 to 100°C
at vapor to liquid ratios of 4:1 to 1:1 (X=4to1)and pressures up to 500 kPa (70 psi), but the precision statement (see Section 16) may not be applicable.
1.2The vapor pressure (VP
1.2 This test method also covers the use of automated vapor pressure instruments to determine the vapor pressure exerted in
vacuum by aviation turbine fuels. This test method is suitable for testing aviation turbine fuel samples with boiling points above
0°C (32°F) that exert a vapor pressure between 0 and 110 kPa (0 and 15.5 psi) at a vapor-to-liquid ratio of 4:1, in the temperature
range from 25 to 100°C (77 to 212°F).
1.3 The vapor pressure (VP ) determined by this test method at a vapor-liquid ratio of 4:1 (X = 4) of gasoline and
X
gasoline–oxygenate blends at 37.8°C can be correlated to the dry vapor pressure equivalent (DVPE) value determined by Test
Method D5191 (see 16.2).
1.3
1.4) determined by this test method at a vapor-liquid ratio of 4:1 (X = 4) of gasoline and gasoline-oxygenate blends at 37.8°C
can be correlated to the dry vapor pressure equivalent (DVPE) value determined by Test Method D 5191 (see 16.3). This condition
does not apply when the sample is aviation turbine fuel.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 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 and health practices and determine the applicability of regulatory
limitations prior to use. For specific warning statements, see 7.2-7.8.
