ASTM D6732-02 PDF

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.
