EN590 sets specifications for various physical and chemical properties of diesel fuel, including: Cetane Number: A measure of the ignition quality of diesel fuel. Density: The mass per unit volume of the fuel. Sulphur Content: The maximum allowable sulphur content in the fuel, which is a major determinant of emissions of sulphur dioxide (SO2) and particulate matter. Flash Point: The temperature at which the fuel vaporizes to form a combustible mixture with air.
The range of temperatures over which the fuel vaporizes during heating.
Specifications related to the fuel's ability to flow at low temperatures without gelling or waxing.
The ability of the fuel to lubricate engine components and prevent wear and tear.
EN590 compliance is closely linked to European emission standards for road vehicles, which specify maximum allowable emissions of pollutants such as nitrogen oxides (NOx), particulate matter (PM), hydrocarbons (HC), and carbon monoxide (CO). Low-sulfur diesel fuels like those meeting EN590 specifications are essential for meeting stringent emission standards and reducing air pollution.
EN590 allows for the blending of diesel fuel with biodiesel derived from renewable sources such as vegetable oils or animal fats. Blending biodiesel with conventional diesel fuel can reduce greenhouse gas emissions and dependence on fossil fuels. EN590 specifies the maximum allowable biodiesel content (typically up to 7% vol) and sets quality requirements for blended fuels to ensure compatibility with diesel engines.
EN590 is part of a broader effort to harmonize fuel quality standards across Europe to facilitate the free movement of goods and vehicles within the European Union (EU). It is periodically updated to reflect advances in fuel technology, changes in engine design, and evolving regulatory requirements.
Compliance with EN590 standards is mandatory for diesel fuel sold in European Union member states and other countries that adopt European fuel quality regulations. Regulatory authorities may conduct regular inspections and testing to ensure that fuels meet EN590 specifications.
Overall, EN590 plays a crucial role in ensuring the quality, performance, and environmental compatibility of diesel fuel used in road vehicles across Europe. Compliance with these standards is essential for minimizing emissions, protecting public health, and promoting sustainable transportation.
