EN 590 governs the diesel fuel for the automotive industry and other machinery within European countries. It is also referred to as ultra-low sulphur diesel. Diesel fuel is further classified into two types that own unique specifications that are governed by this standard. These categories are:

Their specifications are described below:

EN 590 Gas Oil Specifications

Gas oil, also known as red diesel, is used for untaxed vehicles, stationary diesel engines and small boiler and furnace applications. It comes with a red dye, which is used to mark the product. The following table shows the chemical and physical specifications of gas oil that are required by the EN590 standard:
