|Significance and Use|
5.1 The determination of class group composition of aviation turbine fuels is useful for evaluating quality and expected performance, as well as compliance with various industry specifications and governmental regulations.
1.1 This test method is a standard procedure for the determination of total aromatic, monoaromatic and diaromatic content in aviation turbine fuels using gas chromatography and vacuum ultraviolet detection (GC-VUV).
1.2 Concentrations of compound classes and certain individual compounds are determined by percent mass or percent volume.
1.2.1 This test method is developed for testing aviation turbine engine fuels having concentration test results ranging from 0.487 % to 27.876 % by volume total aromatic compounds, 0.49 % to 27.537 % by volume monoaromatics and 0.027 % to 2.523 % by volume diaromatics.
Note 1: Samples with a final boiling point greater than 300 °C that contain triaromatics and higher polyaromatic compounds are not determined by this test method.
1.3 Individual hydrocarbon components are not reported by this test method, however, any individual component determinations are included in the appropriate summation of the total aromatic, monoaromatic or diaromatic groups.
1.3.1 Individual compound peaks are typically not baseline-separated by the procedure described in this test method, that is, some components will coelute. The coelutions are resolved at the detector using VUV absorbance spectra and deconvolution algorithms.
1.4 This test method has been tested for aviation turbine engine fuels; this test method may apply to other hydrocarbon streams boiling between hexane (68 °C) and heneicosane (356 °C), including sustainable alternative jet fuels but has not been extensively tested for such applications.
1.5 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 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.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
