EN 590

From Wikipedia, the free encyclopedia

EN590 describes the physical properties that all diesel fuel must meet if it is to be sold in the European Union, Iceland, Norway andr Switzerland.

It allows the blending of up to 5% Biodiesel with 'conventional' diesel - a 95/5 mix, also called BD5. In some countries such as France, all diesel sold routinely contains this 95/5 mix.
