EN 590 is the European standard for automotive diesel fuel (gas oil) used in compression-ignition engines. In international trade, 'EN590' is used loosely to describe road diesel meeting that standard — but the standard itself defines a framework of parameters, and only a certificate of analysis for the actual cargo confirms what is being delivered.
Key parameters
| Parameter | Typical requirement | Why it matters |
|---|---|---|
| Sulphur content | Max 10 mg/kg (10 ppm, 'ULSD') | Emissions, engine compatibility, regulation |
| Cetane number | Min 51 (standard) | Combustion quality, cold starting |
| Density at 15 °C | 820.0 – 845.0 kg/m³ | Energy content, metering, taxation |
| Distillation (95%) | Max 360 °C | Combustion and deposit behaviour |
| Cold filter plugging point | Varies by region/season | Winter operability |
| Flash point | Above 55 °C | Safety classification |
Documentation in physical trade
Diesel cargoes are typically supported by a certificate of quality/analysis from the load port, independent inspection (such as SGS or equivalent) at loading and discharge, a bill of lading, certificate of origin and the usual shipping documents. Buyers should agree the inspection regime and the exact specification schedule in the contract before nomination.
BNM Petroleum coordinates EN 590-grade diesel supply on a delivered- or load-port basis with inspection and full documentation. Specifications are agreed per cargo; no stock or price claims are made on this website — availability is provided upon request.
