5. Significance and Use
5.1 The CFPP of a fuel is suitable for estimating the lowest
temperature at which a fuel will give trouble-free flow in
certain fuel systems.
5.2 In the case of diesel fuel used in European light duty
trucks, the results are usually close to the temperature of failure
in service except when the fuel system contains, for example,
a paper filter installed in a location exposed to the weather or
if the filter plugging temperature is more than 12°C below the
cloud point value in accordance with Test Method D 2500,
D 5771, D 5772, or D 5773. Domestic heating installations are
usually less critical and often operate satisfactorily at temperatures somewhat lower than those indicated by the test results.
5.3 The difference in results obtained from the sample as
received and after heat treatment at 45°C for 30 min can be
used to investigate complaints of unsatisfactory performance
under low temperature conditions.
