EN Biodiesel Standards

Several standards establish the specifications for biodiesel fuels in the European Union:

  • EN 14214 includes specifications for fatty acid methyl ester (FAME) fuel for diesel engines. B100 that meets this standard could be used unblended in a diesel engine (if the engine has been adapted to operate on B100) or blended with petroleum diesel fuel.
  • EN 590, the European diesel fuel specification, is also applicable to biodiesel blends up to 7% of FAME.
  • EN 16734 covers diesel fuel with biodiesel up to 10% FAME
  • EN 16709 covers diesel fuel with 14% to 20% FAME or 24% to 30% FAME

Table 1 summarizes the generally applicable requirements and referee test methods for EN 14214 [6213].
