ASTM D5188-09
Historical Standard: Standard Test Method for Vapor-Liquid Ratio Temperature Determination of Fuels (Evacuated Chamber Method)
ASTM D5188
Scope
1.1 This test method covers the determination of the temperature at which the vapor formed from a selected volume of volatile petroleum product saturated with air at 0 to 1Ā°C (32 to 34Ā°F) produces a pressure of one atmosphere in an evacuated chamber of fixed volume. This test method is applicable to samples for which the determined temperature is between 36 and 80Ā°C (97 and 176Ā°F) and the vapor-liquid ratio is between 8 to 1 and 75 to 1.
Note 1āWhen the vapor-liquid ratio is 20:1, the result is intended to be comparable to the results determined by Test Method D 2533.
Note 2āThis test method may also be applicable at pressures other than one atmosphere, but the stated precision may not apply.
1.2 This test method is applicable to both gasoline and gasoline-oxygenate blends.
1.2.1 Some gasoline-oxygenate blends may show a haze when cooled to 0 to 1Ā°C. If a haze is observed in 11.5, it shall be indicated in the reporting of results. The precision and bias statements for hazy samples have not been determined (see Note 9).
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use. For specific warnings, see 7.2 and 8.1.1.
