Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Active view current version of standard Translated Standard: Alternative techniques and methods may classify and quantify individual aromatic hydrocarbon types differently.

Quantification is by external calibration using a single aromatic compound, which may or r6591 not be representative of the aromatics in the sample, for each aromatic hydrocarbon type. Test Method Dcurrently specified by CARB, is also applicable to the astmm of both total aromatics d591 polynuclear aromatic hydrocarbons in diesel fuel. 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.

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. Test Method D is applicable to the determination of both total aromatics and polynuclear aromatic hydrocarbons in diesel fuel, but is much more costly and time-consuming to perform.

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