EN 590 is a standard published by the European Committee for that describes the physical properties that all automotive diesel fuel must meet. EN590 separate in 10ppm and 50ppm Euro. EN 590 Gas Oil is a 10 ppm (parts per million) sulphur content gas oil. It has a higher cetane number than A2 Class Gas Oil (another 10ppm sulphur content class of red diesel), making it better suited to internal combustion engines in off-road vehicles.
Diesel EN590 (Ultra Low Sulphur Diesel) describes the physical properties that all automotive diesel fuel must meet if it is to be sold in the European Union and Britain. 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). Automotive diesel has national variants but the usual variants traded are EN560 and EN590 which are specified by International Organization for Standardization (ISO) in Paris. Ultra-low–sulfur diesel (ULSD) is a fuel with substantially lower sulfur content. Since 2006, almost all of the petroleum-based diesel fuel available in Europe and North America has been of a ULSD type.
The quality of European diesel fuels is specified by the EN590 standard. While these specifications are not mandatory, they are observed by all fuel suppliers in Europe. It is intended for application in diesel engines. Diesel motor fuel quality meets the requirements of European Standard EN590.
For operation in the conditions of a temperate climate following marks of fuel diesel automobile, EN590 are offered:
The entire volume of produced diesel fuel quality meets the requirements for fuels for vehicles of Euro 4 and Euro 5. Low sulfur content reduces emissions of sulfur oxides into the atmosphere, which is especially important for inhabitants of big cities.
Many countries in Europe require diesel fuel to meet a specific class in winter. In Central and Western Europe the Winter Diesel must meet Class F conditions at least from the beginning of December to the end of February. During a transitional period (mostly October and April) a lower Class must be met. In the Scandinavian countries, the Winter Diesel must meet Class 2 conditions. Some mineral groups offer both types commonly known as Winter Diesel and Arctic Diesel.
