The Euro-5 classification, which is widespread among consumers, was the first after the Soviet GOST standards to become widespread when labeling Russian diesel. You can see more foreign cars than domestic ones on Russian roads. The European standard EN 590-2009 is not valid in Russia, but the Russian GOST 32511-2013 is based on it.
Euro-5 or EN 590-2009 is a standard adopted by the European Union that defines the permissibility of using certain classes of diesel in certain climatic zones. Russia and the countries of the Customs Union control two parameters when labeling diesel fuel for sale: the content of sulfur impurities (environmental friendliness) and the filtering temperature (climatic uses).
At the same time, in the quality certificates for diesel fuel and other petroleum products, different characteristics of the batch must be indicated — viscosity, water content, cetane number, or flammability.
