1.1 This test method covers the determination of copper in jet fuels in the range of 5 µg ⁄kg to 100 µg ⁄kg using graphite furnace atomic absorption spectrometry. Copper contents above 100 µg ⁄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. No other units of measurement are included in this standard.
