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. 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 °C.
For referee testing the requirement to employ 1 l 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 1 l and 250 ml sample containers. Annex A provides information on the precision values when using 50 ml at 37,8 °C or using 1 l samples at a test temperature of 50,0 °C.
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 °C.
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 "% (V/V)" are used to represent the mass, respectively the volume fraction.
WARNING Use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability ...
