Historical Standard: ASTM D2889-95(2005)e1 Standard Test Method for Calculation of True Vapor Pressures of Petroleum Distillate Fuels
SUPERSEDED (see Active link, below)
ASTM D2889
1. 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 data are usually not available for petroleum fuels. However, if both the critical pressure and critical temperature are known, the values shall be used as the coordinates in to establish a critical point to be used instead of the focal point established as described in ; and the calculations described in through are not required. If either a determined true boiling point or determined equilibrium flash vaporization temperature at 0 % distilled at atmospheric pressure is known, the determined value shall be used to establish the lower limit of the bubble-point line referred to in .
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.
