Significance and Use

At high temperatures aviation turbine fuels can oxidize and produce insoluble    deposits that are detrimental to aircraft propulsion systems. Very low copper    concentrations (in excess of 50 μg/kg) can significantly accelerate this thermal instability of aviation turbine fuel. Naval shipboard aviation fuel delivery systems    contain copper-nickel piping, which can increase copper levels in the fuel. This test    method may be used for quality checks of copper levels in aviation fuel samples    taken on shipboard, in refineries, and at fuel storage depots.

Scope

1.1 This test method covers the determination of copper in jet fuels in the range of 5 to 100 g/kg using graphite furnace atomic absorption spectrometry. Copper contents above 100 g/kg may be determined by sample dilution with kerosine to bring the copper level into the aforementioned method range. When sample dilution is used, the precision statements do not apply.

1.2 The values stated in SI units are to be regarded as standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
