Scope

This standard specifies a method for the gravimetric determination of particulate contaminant in aviation turbine fuel by laboratory filtration. It should be recognised that, due to the difficulty associated with obtaining reliable results, a single one-off determination by this method is of limited value. The prime applicability of this method is to indicate significant trends or changes in particulate levels at specific locations where typical values have been established. This information may be used to monitor the impact of operational changes.

Precision has only been determined for 51 samples in the range 0,00 mg/l to 0,60 mg/I.

NOTE 1 - Particulate matter present in aviation turbine fuels should be minimized to avoid filter plugging and other operational problems. Tolerable levels of particulate contaminants are not established for all points in fuel distribution systems but have to be stringently controlled.
