ASTM D8267-24 pdf download,Standard Test Method for Determination of Total Aromatic, Monoaromatic and Diaromatic Content of Aviation Turbine Fuels Using Gas Chromatography with Vacuum Ultraviolet Absorption Spectroscopy Detection (GC-VUV).

The present test method establishes a standardized process for assessing the levels of total aromatic, monoaromatic, and diaromatic constituents in aviation turbine fuels through the use of gas chromatography coupled with vacuum ultraviolet detection (GC-VUV).

The quantification of various compound classes and specific compounds is conducted on a percentage mass or volume basis. It is important to note that this method does not provide a report on individual hydrocarbon components; instead, any identified components are incorporated into the respective totals for aromatic, monoaromatic, or diaromatic categories.

In the process outlined by this method, individual compound peaks are generally not resolved at the baseline, meaning that certain compounds may elute simultaneously. The resolution of these overlapping peaks is achieved at the detection stage, utilizing vacuum ultraviolet absorbance spectra and deconvolution techniques.

The validity of this test method has been verified for aviation turbine engine fuels, including synthetic alternative jet fuels. While it is theoretically applicable to other hydrocarbon mixtures with boiling points ranging from hexane (68°C) to heneicosane (356°C), the method has not been rigorously tested for such diverse applications.

Regarding units of measurement, values expressed in the International System of Units (SI) are to be considered the norm. This standard does not recognize or include any other units of measurement.
