1. Scope 1.1 This method describes the procedure for determining the filter plugging
tendency of diesel fuels at low temperature due to the formation of wax
crystals. 1.2 The method applies to all distillate diesel fuels. Fuels passing this
test are expected to provide satisfactory fuel flow in automotive
equipment at temperatures equal to or higher than that of the test. 1.3 This method is referenced and compared in ASTM D 4539. 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 existing applicable
