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. Active view current version of standard Translated Standard: It is the responsibility of the user of this standard to establish appropriate safety and aetm practices and determine the applicability of regulatory limitations prior to use.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Mono-alkenes do not interfere, but conjugated di- and poly-alkenes, if present, are possible interferents. Link to Active This link will always route to the current Active version of the standard.

Test Method Dhowever, specifies the use of supercritical fluid chromatography equipment that may not be readily available. Test Method D is applicable to the determination of both total aromatics and polynuclear aromatic hydrocarbons in diesel fuel, axtm is much more costly and time-consuming to perform.

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. Mono-alkenes do not interfere, but conjugated di- and poly-alkenes, if present, are possible interferents.

Test Method D astn, currently specified by CARB, is also applicable to the determination of both total aromatics and polynuclear aromatic hydrocarbons in diesel fuel.
