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

Note 1—This test method is not intended for use in specifications.

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

1.3 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.
