Methods of testing petroleum and associated products - Low temperature flow test (LTFT) for diesel f...
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…

1.1 La présente méthode permet de déterminer la tendance des combustibles diesels à colmater les filtres à
basse température généralement en raison de la formation de cristaux de cire (voir la note en 6.1).
1.2 La méthode s’applique à tous les combustibles diesels distillés. Il est prévu que les combustibles s’écouleront
librement dans le matériel automobile à des températures égales ou…
