Tankerman · Cargo Properties — RVP
Reid Vapor Pressure (RVP) of a cargo is a measure of its:
- ADensity relative to water
- BVolatility — its tendency to give off vapor✓ Correct
- CSulfur content
- DViscosity at 100°F
Explanation
RVP indicates volatility: the higher the RVP, the more readily the cargo vaporizes. High-RVP cargoes (e.g., gasoline) require greater attention to vapor control and venting than low-RVP products.
Authority: ASTM D323 (Reid Vapor Pressure); ISGOTT
