Liquid petroleum products - Vapour pressure - Part 1: Determination of air saturated vapour pressure (ASVP) and calculated dry vapour pressure equivalent (DVPE)
This European standard specifies a method for the measurement of the air-saturated vapor pressure (en: air saturated vapour pressure, ASVP) (absolute pressure) in the vacuum of volatile, low viscosity petroleum products, components, ethanol blends up to 85% to (V /) (V) and use products that contain air, is exercised. The pressure corresponding to the dry vapor pressure (en: dry vapour pressure equivalent, DVPE) can be calculated on the basis of the measured value for the air saturated vapour pressure. The terms used in the test described in this standard are a vapor liquid ratio of 4: 1 and a test temperature of 37.8 ° C. The tester is not wetted during the test with water, the procedure is suitable for samples with as well as without oxygenates; Water dissolved in the sample is not taken into account. This procedure is for testing air-saturated samples with a DVPE between 15.5...
