EN590 describes the physical properties that all automotive diesel fuel must meet if it is to be sold in the European Union, Croatia, Iceland, Norway and Switzerland.
The EN 590 had been introduced along with the European emission standards. With each of its revisions the EN 590 had been adapted to lower the sulphur content of diesel fuel – since 2007 this is called ultra-low sulphur diesel as the former function of sulphur as a lubricant is absent (and needs to be replaced by additives).
The quality of European diesel fuels is specified by the EN 590 standard. While these specifications are not mandatory, they are observed by all fuel suppliers in Europe.
Automobile diesel en 590 is intended for application in diesel engines. Diesel motor fuel quality meets the requirements of European Standard EN 590. For operation in the conditions of a temperate climate following marks of fuel diesel automobile EN 590 are offered: Grade C – limiting filterability temperature -5 ° C; Grade D – limiting filterability temperature -10 ° C; Grade E – limiting filterability temperature – 15 ° C; Grade F – limiting filterability temperature -20 ° C. The entire volume of produced diesel fuel quality meets the requirements for fuels for vehicles of Euro 4 and Euro 5. Low sulfur content in diesel EN 590 reduces emissions of sulfur oxides into the atmosphere, which is especially important for inhabitants of big cities.
