摘要:
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.
