The purpose of the proposed method is to offer a secondary rapid means of checking key quality perimeters of aviation turbine fuels on an immediate need to know basis at the point of dispensation such as busy airports, pipelines, refineries, and military operations. The method can be used for aviation turbine fuel process unit analysis and control in refineries as it has been demonstrated that the repeatability is tighter than the ASTM primary test methods for many of the properties determined. The reproducibility is subject to the error of the primary methods and that due to the spectroscopes and modeling used to determine the properties. The method is not meant to replace the primary test methods that are used to establish acceptability between manufacturers and customers and cannot replace all of the test methods required in D1655 and other specifications for aviation turbine fuels. This test method is limited to conventional aviation turbine fuels produced from middle distillation of hydrogenated petroleum crude oils. The spectra of non-conventional jet fuels (synthetic and renewable sources) blended with conventional jet fuels are significantly different than those for conventional jet fuels. Properties that are indicated to be out of specifications by this test method should be retested by the primary ASTM methods in a laboratory.
