DIN EN 13016-2-2007 液化石油产品.蒸气压力.第2部分:40℃和100℃之间绝对压力(AVP)的测定
Liquid petroleum products - Vapour pressure - Part 2: Determination of absolute pressure (AVP) between 40 °C and 100 °C; English version of DIN EN 13016-2:2007-11
This European Standard specifies a method for the determination of absolute vapour pressure of liquid
petroleum products at elevated temperatures.
The conditions used in the test described in this standard are a vapour to liquid ratio of 3:2 and an initial injection temperature of 37,8 ℃ or 30,0 ℃.
The method described is suitable for testing air-saturated samples that exert an air-saturated vapour pressure of between 9 kPa and 500 kPa at temperatures between 40 ℃ and 100 ℃.
This European Standard is applicable to fuels containing oxygenated compounds up to the limits stated in the
relevant EC Directive 85/536/EEC [3].
NOTE 1 If a sample injection is into a test chamber which is raised to 37,8 ℃ and the vapour to liquid ratio is 4:1, the
initial measurement corresponds with the measurement in Part 1 of this standard.
NOTE 2 For the purposes of this European Standard, the term "% (VA/)" is used to represent the volume fraction.
