Scope

This standard specifies a method for the gravimetric determination of particulate contaminant in the range 0,00 mg/l to 2,00 mg/l in aviation turbine fuel using a field monitor.

NOTE 1 Where it is not possible to use a field monitor, particulate contaminant in a fuel sample should be determined by laboratory filtration in accordance with IP 423.

NOTE 2 The particulate matter present in aviation turbine fuels should be minimized in order to avoid filter plugging and other operational problems. Tolerable levels of particulate contaminants are not established for all points in fuel bistribution systems but have to be stringently controlled. The total contaminant measurement is normally of most interest.

NOTE 3 Procedures for the sampling and rapid qualitative assessment of contamination are provided in annexes A and B. The colour rating method (see annex B) is useful for fuel system monitoring purposes. No quantitative relationship exists between gravimetric and colour rating test results.
