## Two products, two specifications

EN 590 is the European standard for automotive diesel. It sets a maximum of 10 mg/kg of sulfur, which is why the product is often called 10 ppm or ultra-low-sulfur diesel.

Gas oil 50 ppm is traded on a contract specification that limits sulfur to 50 ppm. Its other properties are agreed for each trade, so the buyer should name them in the inquiry.

## Main EN 590 limits

| Property | EN 590 limit |
| --- | --- |
| Sulfur | 10 mg/kg maximum |
| Cetane number | 51 minimum |
| Cetane index | 46 minimum |
| Density at 15 °C | 820 to 845 kg/m³ |
| Flash point | Above 55 °C |
| FAME (biodiesel) content | 7% by volume maximum |
| Water | 200 mg/kg maximum |
| Lubricity, wear scar at 60 °C | 460 µm maximum |

Cold-weather properties depend on the climate class named in the contract. The temperate classes A to F set a cold filter plugging point from +5 °C down to −20 °C.

## How a diesel trade is handled

- The buyer names the standard, the climate class and the quantity.
- An independent inspector samples and tests the product at loading.
- Certificates of quality and quantity go with the shipping documents.
- Delivery terms, such as FOB, CIF or DAP, are fixed in the contract.

## Questions we are asked

Yes. For sulfur in diesel, 10 ppm by mass and 10 mg/kg describe the same limit.
