CAN/CGSB-3.0 No. 140.1-2022

1.1 This method describes a procedure for determining the filter plugging tendency of diesel fuels at low temperature, usually due to the formation of wax crystals (see note in 6.1). 1.2 The method applies to all distillate diesel fuels. Fuels are expected to provide satisfactory fuel flow in automotive equipment at temperatures equal to or higher than the minimum pass temperature as described in 3.1.1. 1.3 This method is referenced in ASTM D4539-17 (Note 1). 1.4 The testing and evaluation of a product against this method 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 method 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. 1.5 Units of measurement – Quantities and dimensions used in this standard are provided in units from the International System of Units (SI units). This standard expresses the industry standard nominal measurements in North America of “% by mass” and “% by volume”. The SI equivalent expressions for these units are % (m/m) and % (V/V) respectively.
