This European Standard specifies a method for the determination of the total pressure, exerted in vacuo, by volatile, Iow viscosity petroleum products, components, and feedstocks containing air. A dry vapour pressure equivalent (DVPE) 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 and a test temperature of 37,8 ℃. For referee testing the requirement to employ 1 I sample containers is mandatory. However, due to sample container size restrictions in taking automatic samples from vapour-locks either onboard a ship or from some land based storage tanks, the precision for 250 ml containers forms part of this standard and shall be used for referee purposes. NOTE 1 This standard states precision for both I I and 250 ml sample containers. Annex A I~rovides information on the precision values when using 50 ml at 37,8 ℃ or using 1 I samples at a test temperature of 50,0 ℃. The equipment is not wetted with water during the test, and the method described is therefore suitable for testing samples with or without oxygenates; no account is taken of dissolved water in the sample. This method described is suitable for testing air-saturated samples that exert an air-saturated vapour pressure of between 9,0 kPa and 150,0 kPa at 37,8 ℃. This document is applicable to fuels containing oxygenated compounds up to the limits stated in the relevant EC Directive 85/536/EEC [4]. NOTE 2 For the purposes of this European Standard, the term "% (m/m)"and "% (VA/)" are used to represent the mass, respectively the volume fraction.
