This draft standard 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 (26 psi). 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 (26 psi). Procedure D for aviation gasoline with a vapor pressure of approximately 50 kPa (7 psi).
