Standard test method for vapor pressure of petroleum products (reid method)

Scope

This standard describes test method for determination Vapor pressure, an important physical property of volatile liquids. This test method is used to determine the vapor pressure at 37.8°C of petroleum products and crude oils with initial boiling point above 0°C. This test method covers procedures for the determination of vapor pressure of gasoline, volatile crude oil, and other volatile petroleum products. Procedure A is applicable to gasoline and other petroleum products with a vapor pressure of less than 180 kPa. Procedure B may also be applicable to these other materials, but only gasoline was included in the interlaboratory test program to determine the precision of this test method. Procedure C is for materials with a vapor pressure of greater than 180 kPa. Procedure D for aviation gasoline with a vapor pressure of approximately 50 kPa .
