EN 590 is the benchmark for automotive diesel fuel in Europe. It was introduced to align with evolving European emission standards originally; the specification has undergone several revisions to reduce environmental pollutants, most notably sulphur.
Sulphur used to provide a natural lubricant in diesel but was eliminated because of the emissions caused by diesel that sulphur contributed to. Then people started to demand fewer emissions, creating substitutes for more refined fuel, followed by the introduction of various higher-quality additives to satisfy and maintain performance and lubrication for modern engines.
Key EN 590 Specifications
The EN 590 standard outlines many requirements for diesel characteristics that promote efficiency, function, and environmental friendliness. Here are some key highlights that you should be know about:
Sulphur Content: The amount of sulphur has decreased from 0.200% in Euro 1 to only 10 mg/kg in Euro 5 and Euro 6. This led to the emergence of ultra-low-sulphur diesel (ULSD).
Cetane Number: A rating of the quality of combustion under specific operational conditions—the EN 590 requires a cetane rating of 51 to improve engine operation and cold starting.
Fatty Acid Methyl Esters (FAME): FAME quality biodiesel can be blended up to 7% per EN 590, creating a pathway for the use of biodiesel and promoting the use of more renewable sources of energy, yet it does not compromise fuel quality.
Density and Viscosity: Density must fall within the range of 820–845 kg/m³, and viscosity is also tightly controlled with a range of 2.00–4.50 mm²/s; density and viscosity must have consistency between seasons and across multiple climate conditions, as well as various engine technologies.
The specifications outlined not only support vehicle operational performance but also support climate targets by reducing harmful emissions and support the usage of alternative energy sources.
EN 590 and Winter Diesel Fuel
One of EN 590’s most practical elements is its classification of seasonal diesel grades based on climate zones. The standard divides diesel into two main categories:
Temperate Zones (Classes A–F) – Designed for milder European climates, these grades ensure cold filter plugging point (CFPP) thresholds from +5°C down to -20°C.
Arctic Zones (Classes 0–4) – These are specially formulated for extreme conditions, with CFPP as low as -44°C and enhanced cloud point requirements.
In regions like Scandinavia, where winter temperatures regularly drop below freezing, Class 2 or higher arctic diesel is mandated to prevent fuel gelling and maintain operability.
At Telematique Limited, we supply products compatible with EN 590 classifications and cater to varying seasonal requirements to support industries across Europe and colder global regions.
Although EN 590 is a European standard and its connections reach far beyond the boundaries of the EU. Countries in Asia, Africa, and the Middle East are increasingly pursuing diesel specifications similar to EN 590, given EN 590’s acknowledgement of the importance of environmental stewardship alongside product performance.
Moreover, while the GOST R 32511-2013 standard strived to meet local criteria, the GOST standard holds similarities to EN 590 for various properties, such as cetane values, oxidation stability, and sulphur levels. Compatibility of fuels provides easier commerce and compliance regarding regulations around the world.
Why EN 590 Matters for Chemical and Fuel Supply Chains
For companies like Telematique Limited that are part of the global chemicals and fuels business, understanding EN 590 and applying its regulations is more than a simple requirement; it is a competitive advantage. We can ensure that every diesel chemical additive, lubricant, and solvent we provide is compatible with EN 590, which presents assurance to our customers for quality, performance, and overall environmental responsibility.
It doesn't matter if you have cold-weather fuel enhancers, FAME-compatible solvents, or ultra-low-sulphur diesel additives; our products are developed and designed according to the EN 590 standards.
EN 590 is much more than just a technical fuel specification; it is the foundation of modern diesel regulation affecting environmental regulations, engine technology, and chemical products globally.
At Telematique Limited, we are proud to be part of this changing energy landscape and supply products and knowledge that meet the exacting standards of EN 590. We are here to help industries in the UK and across the world to achieve their aspirations of providing high-quality, compliant solutions towards a sustainable future.
