Scope

1.1 This standard specifies the method for determining hydrocarbons in petroleum fractions with a boiling point below 315 °C. The concentration range for determination: the volume fraction of aromatic hydrocarbons is 5% to 99%, the volume fraction of olefins is 0.3% to 55%, and the volume fraction of saturated hydrocarbons is 1% to 95%; this standard can also be used for samples with concentrations exceeding the above range, but the precision has not been determined. This standard is not applicable to samples containing dark components that affect the colorimetric reading of hydrocarbons.
1.2 This standard can be used to determine the full boiling range of petroleum products, but statistical test data show that the precision of this standard is not suitable for narrow petroleum fractions with a boiling point close to 315 °C. Such samples cannot be properly separated, and the determination results are unstable.
1.3 It has not yet been determined whether this standard is applicable to products obtained from non-petroleum mineral fuels such as coal, shale, or oil sands asphalt. Its precision may be suitable for such products, or it may not be suitable.
1.4 The precision of this standard is described in two tables. The first table is applicable to unleaded fuels containing no oxidized compounds, and it may or may not be applicable to automotive gasoline with leaded anti-knock mixtures. The second table is applicable to automotive spark-ignition fuels samples blended with oxidized compounds (such as MTBE, ethanol), with a volume fraction of aromatic hydrocarbons ranging from 13% to 40%, a volume fraction of olefins ranging from 4% to 33%, and a volume fraction of saturated hydrocarbons ranging from 45% to 68%.
1.5 This standard is applicable to samples containing certain oxidized compounds. These oxidized compounds include methanol, ethanol, methyl tert-butyl ether (MTBE), tert-amyl methyl ether (TAME), and ethyl tert-butyl ether (ETBE). Their con
