ASTM D6378-07e1<\/h3>\n

Historical Standard: Standard Test Method for Determination of Vapor Pressure (VPX) of Petroleum Products, Hydrocarbons, and Hydrocarbon-Oxygenate Mixtures (Triple Expansion Method)<\/h4>\n
\n

ASTM D6378<\/h4>\n

Scope<\/strong><\/p>\n

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 samples with boiling points above 0\u00b0C (32\u00b0F) that exert a vapor pressure between 7 and 150 kPa (1.0 and 21psi) at 37.8\u00b0C (100\u00b0F) 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).<\/p>\n

Note 1 <\/p>\n

The test method is suitable for the determination of the vapor pressure of volatile, liquid petroleum products at temperatures from 0 to 100\u00b0C at vapor to liquid ratios of 4:1 to 1:1 (X = 4 to 1) and pressures up to 500 kPa (70 psi), but the precision statement (see Section 16) may not be applicable.<\/p>\n

1.2 The vapor pressure (VPX) determined by this test method at a vapor-liquid ratio of 4:1 (X = 4) of gasoline and gasoline-oxygenate blends at 37.8\u00b0C can be correlated to the dry vapor pressure equivalent (DVPE) value determined by Test Method D 5191 (see 16.2).<\/p>\n

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.<\/p>\n
