significance And Use:
The true vapor pressure of a distillate fuel is a relative measurement, both of the tendency of the most volatile portion of the fuel to gasify, and of the restraining pressure required to prevent... View More
scope:
1.1 This test method describes the calculation of true vapor pressures of petroleum distillate fuels for which distillation data may be obtained in accordance with Test Method D 86 without reaching a decomposition point prior to obtaining 90 volume % distilled.
1.2 The test method may be used to calculate vapor pressures at temperatures between the 0 % equilibrium flash temperature and the critical temperature of the fuel. Provision is included for obtaining a calculated critical temperature for fuels for which it is not known.
1.3 Critical pressure-temperature
1.4 The method is not reliable for distillate fuels having a boiling range of less than 100F (38C) between the Test Method D 86 10 and 90 volume % distilled temperatures.
