Reid vapor pressure definition

Reid vapor pressure means the vapor pressure of crude oil or other volatile petroleum products at 100 degrees Fahrenheit as determined by the latest edition of ASTM D6377 (RVPE): Standard Test Method for Determination of Vapor Pressure of Crude Oil.

Reid vapor pressure means the vapor pressure of crude oil or other volatile petroleum products measured at 100 degrees Fahrenheit and at a 4:1 V/L ratio as determined by the latest edition of ASTM D6377: Standard Test Method for Determination of Vapor Pressure of Crude Oil, and reported as the Reid Vapor Pressure Equivalent (RVPE) as described in appendix X1 using equation X1.1 for unpressurized 1-liter sample containers.

Reid vapor pressure means the absolute vapor pressure of volatile crude oil and volatile nonviscous petroleum liquids except liquefied petroleum gases as determined by American Society for Testing and Materials, Part 17, 1973, D-323-72 (reapproved 1977).

Examples of Reid vapor pressure in a sentence

• The true vapor pressure of each type of crude oil with a Reid vapor pressure less than 13.8 kPa or with physical properties that preclude determination by the recommended method is to be determined from available data and recorded if the estimated maximum true vapor pressure is greater than 3.5 kPa.

• The cover of a new cold cleaner shall be mechanically assisted if the Reid vapor pressure of the solvent is more than 0.3 psia or if the solvent is agitated or heated.

• Available data on the Reid vapor pressure and the maximum expected storage temperature based on the highest expected calendar-month average temperature of the stored product may be used to determine the maximum true vapor pressure from nomographs contained in API Bulletin 2517 (incorporated by reference—see §60.17), unless the Administrator specifically requests that the liquid be sampled, the actual storage temperature determined, and the Reid vapor pressure determined from the sample(s).

• In addition, gasolines shall not have a Reid vapor pressure in excess of the "applicable standard" as determined by the United States Environmental Protection Agency or any more stringent state requirement from time to time in effect.

• Gasoline—A petroleum liquid having a Reid vapor pressure four pounds (4 lbs.) per square inch or greater.
