Reid vapor pressure rvp testing for crude oil fuel other refined petroleum products and petrochemicals is offered by intertek labs on a global basis.
What is rvp testing.
Epa regulates the vapor pressure of gasoline sold at retail stations during the summer ozone season june 1 to september 15 to reduce evaporative emissions from gasoline that contribute to ground level ozone and diminish the effects.

Reid vapor pressure astm d323 is an astm test method which measures the vapor pressure of crude oil and petroleum refined products.
It is defined as the absolute vapor pressure exerted by the vapor of the liquid and any dissolved gases moisture at 37 8 c 100 f as determined by the test method astm d 323 which was first developed in 1930 and has been revised several times the latest version is astm d323 15a.
Rvp only identifies seasonal coronavirus subgroups.
For immunocompromised patients a full rvp is more likely to influence management in practice most laboratories have a limited number of options for molecular viral respiratory testing so clinicians may end up having to interpret the results of a full rvp even if they were only interested in testing for 1 or 2 of the viruses.
