Standard Method of test for Vapor Pressure of Petroleum Products (Reid Method)
|Publication Date:||22 September 1959|
|ICS Code (Petroleum products in general):||75.080|
This method of test covers the determination of the absolute vapor pressure (Note 1) of volatile crude oil and volatile nonviscous petroleum products, except liquefied petroleum gases (Note 2).
NOTE 1.-Because the external atmospheric pressure is counteracted by the atmospheric pressure initially present in the air chamber, the "Reid vapor pressure" is approximately the vapor pressure of the material at 100 F in pounds per square inch absolute.
NOTE 2.-For determination of the vapor pressure of liquefied petroleum gases reference should be made to ASTM Method D 1267, Test for Vapor Pressure of Liquefied Petroleum (LP) Gases.2
