What is BS EN 16136-Automotive fuels about?
BS EN 16136 discusses automotive fuels. The petrochemical industry widely uses Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) for the analysis of trace elements during extraction and refining of crude oil, where trace elements are identified and measured in drilling mud compounds, produced waters, crude oil, and in the refining process.
BS EN 16136 specifies a method based on inductively coupled plasma optical emission spectrometry (ICP OES) for the determination of manganese content from about 0,5 mg/l to about 7,5 mg/l and of iron content from about 1,4 mg/l to about 6,0 mg/l in unleaded petrol containing up to 3,7 % (m/m) oxygen.
Note 1: Manganese as MMT and iron as ferrocene are added to petrol to increase anti-knock properties.
Note 2: Solutions of MMT in petrol are unstable when exposed to light. Low and erratic results are expected if petrol samples are exposed to light prior the analysis
Who is BS EN 16136- Automotive fuels for?
BS EN 16136 on automotive fuels is useful for:
- Petrol refiners
- Petrol suppliers
- Quality control personnel
- Inspection personnel
Why should you use BS EN 16136- Automotive fuels?
A petrol sample is diluted with a hydrocarbon solvent. The solution is introduced directly into the plasma of an ICP OES spectrometer. Iron and manganese contents are calculated by comparison with calibration solutions prepared from suitable iron and manganese compounds. An internal standard is employed to correct viscosity and vapour pressure effects.
BS EN 16136 guides you with reagents and apparatus required for the test. BS EN 16136 helps you with the preparation of solutions, calibration, sample analysis, calculation, and expression of results. BS EN 16136 helps you to reduce impurities of unleaded and petrol and provide quality fuel to your consumer.
What’s changed since the last update?
BS EN 16136:2015 supersedes BS EN 16136:2011, dual numbered as BS 2000-589:2011, which is withdrawn. It includes some technical changes. These include:
- The lowering of the manganese content to allow a specification setting of 2 mg/l of manganese in line with the FQD requirement per 2014-01-01
- The introduction in the scope of determination of iron content, which can be added into petrol as ferrocene
