SCOPE:

This test method covers a procedure for determining the filter plugging tendency (FPT) of distillate fuel oils where the end use demands an exceptional degree of cleanliness. This test method is applicable to fuels within the viscosity range of 1.50 to 6.00 mm2/s (cSt) at 40°C.

MAIN CHARACTERISTICS:

Automatic portable model NBF 241 with 80 columns printer for filter blocking tendency of distillate fuel oils. The pressure
/flow curve is printed at the end of the test as well as the calculation type and results. The assembly consists in 2 parts:
One basement with constant flow pump (20 ml/min ą1 ml), pressure sensor mounted behind the filter (range 0-2 Bar),
level follower for filtered volumes (ą10 ml) and one electronic console base with LCD.
