This standard specifies procedures for determining the Reid vapor pressure of gasoline, volatile crude oil, and other volatile petroleum products.
ASTM D323-26 covers procedures for determining the Reid vapor pressure of gasoline, volatile crude oil, and other volatile petroleum products at 37.8 °C (100 °F). It includes four procedures for different materials and vapor pressure ranges, including aviation gasoline. Reid vapor pressure is important for evaluating fuel volatility, gasoline handling, starting and warm-up performance, and potential vapor lock. The standard also addresses sampling, apparatus, test procedures, reporting, precision, and safety considerations.
Application Scope: Petroleum testing laboratories, refineries, crude oil producers, fuel manufacturers, and aviation fuel testing operations.
