ASTM approves standard biodiesel blend specifications
ASTM International D02 Main Committee approved a trio
of long-awaited ASTM specifications for biodiesel blends.
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
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.
