2、 year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the quantification of the fattyaci
3、d methyl esters(FAME)content in aviation turbine fuel inthe range of 10 mgkg to 400 mg kg by measuring infrared(IR)transmission before,during,and after FAME is convertedto molecules that absorb in a different spectral region thanFAME using a selective chemical reaction facilitated by asuitable catal
4、yst.NOTE1This test method detects all FAME components with peak IRabsorbance at approximately 1749 cm-1and C8to C22carbon chain length.The accuracy of this test method is based on the molecular weight of C16to C18FAME species.The presence of other FAME species with differentmolecular weights could a
5、ffect the accuracy.NOTE2Additives such as antistatic agents,antioxidants,and corro-sion inhibitors are measured with the FAME by mid IR absorption.However,these additives do not contribute to the differential absorptionspectrum used to quantify FAME,as they do not take part in the selectivereaction.
6、1.2 This test method has interim repeatability precisiononly,see Section 15 for more information.1.3 UnitsThe values stated in SI units are to be regardedas standard.No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns,if
