As you might remember from my post this past Tuesday (June 17th), biodiesel received preliminary approval from a subcommittee of ASTM International… an organization that sets standards for a variety of things, including fuels.
Now, biodiesel has cleared the next important hurdle as the full ASTM International D02 Main Committee voted to approve three long-awaited specifications for biodiesel blends. This National Biodiesel Board press release has more:
After more than five years of extensive research and subsequent balloting by the ASTM fuel experts in the blended fuel balloting process, ASTM has finally voted to approve three key sets of biodiesel specifications that should significantly bolster automaker support and consumer demand for biodiesel:
* Changes to the existing B100 biodiesel blend stock specification (ASTM D6751)
* Finished specifications to include up to 5% biodiesel (B5) in the conventional petrodiesel specification (ASTM D975)
* A new specification for blends of between 6 percent biodiesel (B6) to 20 percent biodiesel (B20) for on and off road diesel.
Automakers and engine manufacturers have been requesting a finished blend specification for B20 biodiesel blends for several years, with some citing the need for that spec as the single greatest hurdle preventing their full-scale acceptance of B20 use in their diesel vehicles.
Steve Howell, Chairman of the ASTM Biodiesel Task Force, said, “The new ASTM specifications for B6-B20 blends will aid engine manufacturers in their engine design and testing processes to optimize the performance of vehicles running on biodiesel. The new specifications will also help ensure that only the highest quality biodiesel blends are made available to consumers at the retail pump.”
The standards are expected to garner wider acceptance of the green fuel, especially among automakers and fleet managers.
