Significance and Use | ||||||||
4.1 A knowledge of the composition of hydrocarbon refinery streams is useful for process control and quality assurance. 4.2 Aromatics in gasoline are soon to be limited by federal mandate. This test method can be used to provide such information. |

1. Scope | ||||||||
1.1 This test method covers the determination of paraffins, naphthenes, and aromatics by carbon number in low olefinic hydrocarbon streams having final boiling points of 200 °C or less. Hydrocarbons with boiling points greater than 200 °C and less than 270 °C are reported as a single group. Olefins, if present, are hydrogenated and the resultant saturates are included in the paraffin and naphthene distribution. Aromatics boiling at C1.2 This test method is not intended to determine individual components except for benzene and toluene that are the only C1.3 This test method is applicable to hydrocarbon mixtures including virgin, catalytically converted, thermally converted, alkylated and blended naphtha. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4.1 The abbreviation for SI unit “coulomb” is “C”. 1.5 This standard does not purport to
address all of the safety concerns, if any, associated with its
use. It is the responsibility of the user of this standard to
establish appropriate safety, health, and environmental practices
and determine the applicability of regulatory limitations prior to
use.
