Automotive fuels. Determination of manganese content in unleaded petrol. Flame atomic absorption spectrometric method (FAAS) Ingestion-build-103253 Molecular absorption spectrometric method1 Scope This European Standard specifies a method based on flame atomic absorption spectrometry (FAAS) for the determination of manganese content present as methylcyclopentadienyl manganese tricarbonyl (MMT 1)) in unleaded petrol from about 2 mg l to about 8 mg l. This test method is applicable to unleaded petrol containing up to 3,7 % (m m) oxygen, including those with ethanol up to 10 % (V V). NOTE 1 Manganese as MMT is added to petrol to increase
