:EN 590

{{Short description|Current European Union standard for diesel fuel}}

{{1r|date=March 2018}} EN 590 is a standard published by the European Committee for Standardization that describes the physical and chemical properties that all automotive diesel fuel must meet if it is to be sold in the European Union and several other European countries.

Based on 98/70/EG it allows the blending of up to 7% fatty acid methyl ester biodiesel with 'conventional' diesel - a 7:93 mix.

History

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).

Winter Diesel

The standard EN 590 puts diesel fuel into two groups destined for specific climatic environments. For the "temperate" climatic zones the standard defines six classes from A to F. For the "arctic" climatic zones the standard defines five classes from 0 to 4.[https://books.google.com/books?id=9rq1Jdy3CTUC&dq=cfpp+20+26+32+38+44&pg=PA216] Petroleum Refining: Crude oil, petroleum products, process flowsheets von Jean-Pierre Wauquier, pages 215 and 216

Many countries in Europe require diesel fuel to meet a specific class in winter times. In Central and Western Europe the Winter Diesel (Winterdiesel, diesel d'hiver) 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 (Vinterdiesel) must meet Class 2 conditions. Some mineral groups offer both types commonly known as Winter Diesel (Winterdiesel, diesel d'hiver) and Arctic Diesel (Polardiesel, diesel polaires).
