Fuel quality parameters in the EU are regulated by binding legislation because of their impact on the environment and human health. They do not address certain gasoline and diesel properties that are considered ?technical? due to their impact on vehicle performance, such as copper corrosion in gasoline or water content in diesel. Determination of those properties is left to technical experts working on standards for fuels under the umbrella of the European Committee for Standardization (CEN). They prepare European Standards for Gasoline (EN 228) and update them when necessary. Most recently altered in 2008 for Gasoline fuel. European standards are not mandatory; however all European fuel producers and distributors follow them.
