Diesel fuel containing low levels of biodiesel (B1–B5)

Note: This notice of intent was withdrawn by the responsible SDO on January 16, 2024, as the content of CAN/CGSB-3.520 is being merged with the new edition of CAN/CGSB-3.517.

This standard applies to two types of diesel fuel, Type A, Bx and Type B, Bx. Both are suitable for use in high‑speed diesel engine powered equipment for on-road and off-road applications and in select equipment powered by medium speed diesel engines.

Bx represents biodiesel fuel containing x percent by volume of biodiesel component in the range of 1.0 to 5.

Type A, Bx is intended for use in selected applications such as urban buses, underground mining or when ambient temperatures require better low temperature properties than provided by Type B, Bx.

Fuel meeting this standard may be used for underground mining applications that were formerly covered by CAN/CGSB-3.16 (See footnote b and Annex C for notes related to flashpoint).

Users of fuel meeting this standard are advised to refer to the owner’s manual of their vehicle, engine or equipment, or to consult with their equipment’s manufacturer, regarding the suitability of the specific fuel blend prior to its use^1,2.

See Annex B for regulations that apply to diesel fuels.

The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous.
