In many cases a selection of carefully chosen tests will be sufficient to identify specification failure due contamination or misfuelling. In some cases however it is necessary to conduct full specification testing. EN228 is a standard that defines the properties that petrol must meet to be sold in the EU. The corresponding test suite comprises the following tests:
- Appearance Visual
- RON EN ISO 5164
- MON EN ISO 5163
- Lead content EN 237
- Density EN ISO 12185
- Sulphur content EN ISO 20846
- Oxidation Stability EN ISO 7536
- Distillation EN ISO 3405
- Existent Gum (washed) EN ISO 6246
- Copper Corrosion EN ISO 2160
- HydrocarbonTypes (Aromatics & Olefins) EN 15553
- Benzene Content EN 238
- Oxygenates (oxygen content) EN 13132
- Vapour Pressure EN 13016-1
- VLI Calculation (if required) N/A
- Manganese EN 16135 (ASTM D3831)
