Brief description:	Specifications for minimum requirements and tests for diesel fuel
Latest edition	2014-04
ISO	-

The EN 590 standard describes the properties of diesel fuels , it defines uniform conditions in all EU countries as well as Iceland , Norway and Switzerland . The standard refers to the respective underlying measurement method .

In Germany, which has standard in May 1993, the DIN standard DIN 51601 and in October 2009, DIN 51628 replaced. After adapting DIN EN 590 (May 2010 edition) to the requirements of EC Directive 98/70 / EC, a fatty acid methyl ester admixture of up to 7% by volume ("B7 diesel") is permitted to meet the biofuel quota. The national standard DIN 51628 (August 2008 edition) for B7 diesel is therefore no longer required and is no longer required.

The content of the NATO F-54 standard corresponds to the EN 590 standard.

history

This standard was introduced in connection with the definition of emissions standards that provide for a reduction in sulfur levels for diesel. The requirements for diesel fuels in EN 590 have been adapted accordingly. The tabulated limit values ​​are given in % by weight.

Winter diesel

The EN 590 standard distinguishes between two groups of climatically adapted diesel fuels. Six classes A to F are defined for temperate climatic zones. Five classes 0 to 4 are defined for the arctic climatic zones.

Many countries in Europe require winter diesel of a specific class in winter time. In Central and Western Europe, only class F diesel fuel is for sale at least from the beginning of December to the end of February. In a transition period (usually October and April) a middle class is chosen. In the Scandinavian countries, at least class 2 is required in winter. Sometimes two types (Class F / Class 2) are offered in parallel, referred to as winter diesel and polar diesel ( Arctic Diesel ).

Other diesel specifications

Biodiesel is not covered by the EN 590 standard, but is specifically regulated by the EN 14214 standard.

In the USA, diesel fuels are divided into two main classes (Grade No 1 and Grade No 2) by the ASTM D975 standard, each of which has three sub-classes with different sulfur content (S500, S5000, S15 - the number refers to the maximum sulfur content in ppm ). It should be noted that the cetane number according to this standard must be at least 40, in reality it is 45 (test method in ASTM D 613).

In the Russian Federation, diesel fuels are defined by the GOST R 52368 standard. In Japan, diesel fuels are defined by JIS K 2204 (in grades No.1, No.2 and No.3).
