AUTOMOTIVE DIESEL FUEL CONTAINING LOW LEVELS OF BIODIESEL (B1–B5)
1.1 This standard applies to two types of automotive diesel fuel containing low levels of biodiesel: Type A-ULS, Bx and Type B-ULS, Bx.
1.1.1 Bx represents biodiesel fuel containing x percent by volume of biodiesel component in the range of 1.0 to 5%.
1.2 Fuel to this standard is intended for use in high-speed diesel engines that require ultra low sulphur diesel fuel to meet emission control regulations and in high-speed diesel-powered equipment.
1.3 Limiting values of significant properties are prescribed for two types of diesel fuel containing low levels of biodiesel. These types and their general applicability for use in diesel engines are broadly indicated as follows.
1.3.1 Type A-ULS, 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-ULS, Bx.
1.3.2 Type B-ULS, Bx is intended for use in diesel engine applications.
1.4 Types A-ULS, Bx and B-ULS, Bx may be used interchangeably with fuel meeting CAN/CGSB-3.517, Types A-ULS and B-ULS, respectively.
1.5 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.
1.6 The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use.
