Significance and Use
5.1 The aromatic hydrocarbon content of aviation turbine fuels is a factor that can affect their density, elastomer compatibility, system durability and exhaust emissions. The aromatic hydrocarbon content and the polynuclear aromatic hydrocarbon such as naphthalene content of aviation turbine fuels affect their combustion characteristics and smoke-forming tendencies. These properties are controlled by maximum aromatics and naphthalene content specifications for refined aviation turbine fuels (see Specification ) and by both minimum and maximum aromatic content, and maximum naphthalene content, for semi synthetic aviation turbine fuels (see Specification ).
5.2 The Federal Aviation Administration regulates the aromatic content of aviation fuels, thus requiring an appropriate analytical determination to ensure compliance with the regulations. Producers of aviation fuels will require similar determinations for process and quality control. This test method can be used to make such determinations.
1.1 This test method covers the determination of the concentration of total aromatics, and total polynuclear aromatic hydrocarbons in aviation turbine fuels and other kerosenes by supercritical fluid chromatography within the working range as listed below:
Prop. (mass %)
Method Working RangeA
Valid Test Result RangeB
0.3017 to 3.443
0.144 to 3.893
0.2863 to 24.6256
0.004 to 25.375
1.2 This test method may also be used for the analyses of jet fuels, such as Synthetic Paraffinic Kerosenes (SPK) that contain not less than 0.29 % total aromatics by Test Method .
1.3 This test method includes correlations to test methods Test Method for total aromatics and to Test Method for total naphthalenes content.
1.4 The values stated in SI units are to be regarded as standard. The values stated in inch-pound units are for information only.
1.5 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.
1.6 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.
