This standard specifies the method for the determination of hydrocarbons in petroleum fractions with a boiling point lower than 315°C. Determination of concentration range: the form fraction of aromatics is 5% to 9%. 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 is not determined. This standard does not apply to samples containing dark components affecting the hydrocarbon chromatographic readings. This standard can be used to determine the whole boiling range of 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 separated normally, and the measurement results are unstable. This standard has not been determined for use with products derived from non-petroleum mineral fuels such as coal, shale, or oil sands bitumen, and its precision may or may not be appropriate for such products.
