BS EN 13016-1 specifies a method for the determination of the air saturated vapour pressure (ASVP) (total vapour pressure), exerted in vacuo, by volatile, low viscosity petroleum products, components, ethanol blends up to 85 % (V/V), 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 BS EN 13016-1 are a vapour-to-liquid ratio of 4:1 and a test temperature of 37,8 °C.
BS EN 13016-1 is applicable to fuels containing oxygenated compounds up to the limits stated in the relevant Council Directive 85/536/EEC [10], and for ethanol-fuel blends up to 85 % (V/V) ethanol.
BS EN 13016-1 on determination of ASVP and DVPE is useful for:
Vapour pressure is used as a classification criterion for the safe handling and carriage of petroleum products, feedstocks and components; it has a relationship to the potential for hydrocarbon emissions, under uncontrolled conditions, and thus is the subject of environmental scrutiny.
Vapour pressure limitations are often imposed to prevent pump cavitation during transfer operations. Fuels having a high vapour pressure may vaporize too readily in the fuel handling systems, resulting in decreased flow to the engine and possible stoppage by vapour lock. Conversely, fuels of low vapour pressure may not vaporize readily enough, resulting in difficult starting, slow warm-up and poor acceleration.
BS EN 13016-1 provides you guidance on determination vapour pressure, thus enabling you to measure volatility characteristics of the fuels used in different types of engines with large variations in operating temperatures. Fuels having a high vapour pressure may vaporize too readily in the fuel handling systems, resulting in decreased flow to the engine and possible stoppage by vapour lock. Conversely, fuels of low vapour pressure may not vaporize readily enough, resulting in difficult starting, slow warm-up and poor acceleration.
The method described BS EN 13016-1 is suitable for testing samples with or without oxygenates. This method described is suitable for testing air saturated samples with a DVPE between 15,5 kPa and 106,0 kPa.
BS EN 13016-1:2018 supersedes EN 130161:2007. BS EN 13016-1:2018 includes some technical changes with respect to EN 130161:2007.
BS EN 13016-1:2018 has been updated by enlarging the scope to include ethanol blends of up to 85 % (V/V). The range for the instrument verification fluids has been widened and new typical/consensus values added in an annex. The precision statements have been updated following a global evaluation in 2016.
