Standard type
Biodiesel specifications
Regulating Body
The Canadian General Standards Board (CGSB)
Current Standard
CAN/CGSB-3.520-2011
Applicability
Blends of automotive diesel fuel containing low levels of Biodiesel Esters (blends from B1 to B5)
History
In 2011, CAN/CGSB-3.520 established specifications for blends of automotive diesel fuel containing low levels of Biodiesel Esters (blends from B1 to B5). Most of the requirements mirror those of the automotive diesel fuel specification, CAN/CGSB-3.517. The B1-B5 standard requires that the biodiesel component blended into the fuel meets either ASTM D6751 or EN 14214. A specification for blends with B6 to B20 is being developed.
