Standard Test Method for Vapor Pressure of Gasoline and Gasoline-Oxygenate Blends (Dry Method)

Importancia y uso:

5.1 Vapor pressure is an important physical property of liquid spark-ignition engine fuels. It provides an indication of how a fuel will perform under different operating conditions. For example, vapor pressure is a factor in determining whether a fuel will cause vapor lock at high ambient temperature or at high altitude, or will provide easy starting at low ambient temperature.

5.2 Petroleum product specifications generally include vapor pressure limits to ensure products of suitable volatility performance.

Note 3: Vapor pressure of fuels is regulated by various government agencies.
