EN 590

EN 590 Gas Oil specification table explained.

The table below shows the characteristics that EN 590 Gas Oil must meet, so if you’re using this grade of red diesel for off-road use, you’ll get the most out of your fuel by ensuring you use a supplier that can provide EN 590 red diesel.

There are minimum and maximum values which the fuel must meet in order to be classed as EN 590 gas oil. The typical column lists values for these parameters, all of which lie within the specification limits, and which can be expected for deliveries of this grade of fuel.

These parameters include density at 15°C (typically at this temperature it will have a density of 0.856kg/m3 with a minimum of 0.82kg/m3 required), a typical 0.1% carbon residue value (where the maximum permitted for this grade is 0.3%). The table also shows that the minimum flashpoint (the lowest temperature at which the fuel produces vapour that is an ignitable mixture in air near the surface of the liquid) is 56°C, while typically you can expect A2 Class gas oil to have a flashpoint of more than 62°C.

Other important parameters that this grade of gas oil needs to meet are the cold filter plugging point in winter and summer (the highest temperature at which point the oil will start to gel and cause filter blocking issues). Class A2 gas oil needs to stay fully mobile down to a maximum of -4°C (the typical plugging point is -8°C in summer) and -12°C in winter (typically A2 gas oil maintains full fluidity until -15°C)
