It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Mono-alkenes do not interfere, but conjugated di- and poly-alkenes, if present, are possible interferents.

Alternative techniques and methods may classify and quantify individual aromatic hydrocarbon types differently. Mono-alkenes do not interfere, but conjugated di- and poly-alkenes, if present, are possible interferents.

D66591 Method Dcurrently specified by CARB, is also applicable to the determination of both total aromatics and polynuclear aromatic hydrocarbons in diesel fuel.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Work Item s – proposed revisions of this standard.

California Air Resources Board CARB regulations place limits on the total aromatics content and polynuclear aromatic hydrocarbon content of motor diesel fuel, thus requiring an appropriate analytical determination to ensure compliance with the regulations.

Work Item s – proposed revisions of this standard. Historical Version s – view previous versions of standard.

Quantification is by external calibration using a single aromatic compound, which may or may not be representative of the aromatics in the sample, for each aromatic hydrocarbon type. Quantification is by external calibration using d651 single aromatic compound, which may or may not be representative of the aromatics in the sample, for each aromatic hydrocarbon type.
