Liquid petroleum products - Vapour pressure - Part 1: Determination of air saturated vapour pressure (ASVP)

Scope

This European Standard specifies a method for the determination of the total pressure, exerted in vacuo, by volatile, low viscosity petroleum products, components, and feedstocks containing air. An equivalent dry vapour pressure can be calculated from the air containing vapour pressure (ASVP) measurement. The conditions used in the test described in this standard are a vapour-to-liquid ratio of 4:1, a sample size of 1 l, and a test temperature of 37,8°C. Note 1 See annex A for information on the precision values when using 50 ml samples or using a test temperature of 50,0°C.
