CAN/CGSB-3.0 No. 140.1-2017
Methods of testing petroleum and associated products - Low temperature flow test (LTFT) for diesel fuels
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).
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.
This method is referenced and compared in ASTM D4539.
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.
