Tankerman · Cargo Properties — RVP
A cargo with a high Reid vapor pressure (RVP) will:
- ABe difficult to ignite
- BHave a very high flash point
- CEvaporate readily and generate vapors quickly, increasing venting/vapor hazards✓ Correct
- DSink in water
Explanation
RVP measures volatility at 100°F; a high RVP cargo (e.g., gasoline, light crude) flashes off vapor readily, requiring careful venting/vapor control and contributing to higher loading vapor rates. It correlates with the Grade A classification.
Authority: ASTM D323; ISGOTT
