What is BS EN 13016-2- Determination of absolute vapour pressure of liquid petroleum products about?
BS EN 13016-2 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 BS EN 13016-2 are a vapour to liquid ratio of 3:2 and an initial injection temperature of 37,8 °C or 30,0 °C.
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 °C and 100 °C.
BS EN 13016-2 is applicable to fuels containing oxygenated compounds up to the limits stated in the relevant EC Directive 85/536/EEC [3].
Who is BS EN 13016-2 - Determination of absolute vapour pressure of liquid petroleum products for?
BS EN 13016-2 on determination of absolute vapour pressure of liquid petroleum products is useful for:
- Petroleum industry
- Testing laboratories
- Emission control agencies
- EIA bodies
- Academia/ research institutes
Why should you use BS EN 13016-2- Determination of absolute vapour pressure of liquid petroleum products?
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.
Vapour pressure is one measure of the volatility characteristics of fuels used in many differing 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.
Using test method specified in BS EN 13016-2 you can determine absolute vapour pressure of liquid petroleum products with accuracy and precision, to ensure safe handling and carriage of such products.
BS EN 13016-2 guidance on determination of absolute vapour pressure of liquid petroleum products also helps reduce the impact of hydrocarbon emissions on environment.
What’s changed since the last update?
BS EN 13016-2:2007 supersedes EN 13016-2:2000, which has been revised editorially to clarify a number of steps related to sampling, calibration of the pressure transducer and the procedure. No new precision evaluations have been carried out. The equation to calculate the absolute vapour pressure in the informative Annex A has been corrected.
