Description

1.1 This test method covers a procedure for the determination of total vapor pressure of petroleum products and liquid fuels using automatic vapor pressure instruments. The test method is suitable for testing samples with boiling points above 0 °C (32 °F) that exert a vapor pressure between 7 kPa and 110 kPa (1.0 psi and 16 psi) at 37.8 °C (100 °F) at a vapor-to-liquid ratio of 4:1. The test method is applicable to gasolines containing oxygenates. No account is made of dissolved water in the sample.

Note 1: Because the external atmospheric pressure does not influence the resultant vapor pressure, this vapor pressure is an absolute pressure at 37.8 °C (100 °F) in kPa (psi). This vapor pressure differs from the true vapor pressure of the sample due to some small vaporization of the sample and dissolved air into the air of the confined space.
