EN 590

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

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

NATO F -54 standard incorporates the content of the standard EN 590

History

This standard was introduced in connection with the establishment of emission standards, which provides for a reduction in the sulfur values ​​for diesel. Accordingly, the requirements have been adjusted to Dieselkrafstoffe in EN 590.

Properties and test methods

Winter diesel

The EN 590 standard distinguishes between two groups of climatically adapted diesel fuels. For the temperate climate zones ( " temperate " climatic zones ) are six classes A to F defined. For the arctic climate ( " arctic " climatic zones ) are five classes 0 to 4 defined.

Comments

Many countries in Europe are calling winter diesel a specific class in the winter time. In Central and Western Europe at least from the beginning of December only diesel fuel class F is on sale until the end of February. In a transitional period (usually October and April ) have an average class is chosen. In the Scandinavian countries, at least class 2 is required in the winter time. Partial two varieties (Class F / Class 2) are offered in parallel, as winter diesel (german winter diesel) and Arctic diesel (English Arctic diesel ) respectively.

Other diesel specifications

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

Diesel fuels are divided into the U.S. by the standard ASTM D975 into two main classes ( Grade No. 1 and Grade No. 2), the three sub-classes with different sulfur contents ( S500, S5000, S15 - the number refers to the maximum ppm sulfur). Note that the least cetane number of this standard is located at 40 (test method ASTM D 613).

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