True vapor pressure means the equilibrium partial pressure exerted by a petroleum liquid as determined in accordance with methods described in American Petroleum Institute (API) Bulletin 2517, Evaporation Loss from External Floating Roof Tanks, 1980. The API procedure may not be applicable to some high viscosity or high pour crudes. Available estimates of true vapor pressure may be used in special cases such as these.
True vapor pressure means the equilibrium partial pressure exerted by petroleum liquid as determined in accordance with methods described in American Petroleum Institute Bulletin 2517, Evaporation Loss from Floating Roof Tanks, 1962.
True vapor pressure means the equilibrium partial pressure exerted by a petroleum liquid as determined in accordance with methods described in American Petroleum Institute Bulletin 2517, Evaporation Loss from External Floating-Roof Tanks, Second Edition, February 1980 (incorporated by reference—see §60.17).
Examples of True vapor pressure in a sentence
True vapor pressure at maximum hourly and annual average storage temperature.
True vapor pressure means the pressure exerted when a solid or liquid is in equilibrium with its own vapor.
True vapor pressure "as stored" shall be determined on an instantaneous basis under conditions representing expected worst case conditions.
True vapor pressure of the organic liquid stored shall be less than 11.0 psia.

More Definitions of True vapor pressure
True vapor pressure means the absolute pressure in pounds per square inch (kilopascals) of a pure vapor in equilibrium with its pure liquid or solid form at a given temperature.
True vapor pressure means the resulting temperature dependent vapor pressure as measured in accordance with ASTM D6377 (most current version), specifically applied as VPCR4(X) where VPCR is the vapor pressure of the crude, (4) is the vapor/liquid ratio of the test condition and (X) is the equilibrium temperature at which the test is conducted.
