2、he number immediately following the designation indicates the 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.Scope*
3、1.1 This test method specifies a rapid screening methodusing flow analysis by Fourier transform infrared(FA-FTIR)spectroscopy with partial least squares(PLS-1)processing forthe determination of the fatty acid methyl ester(FAME)content of aviation turbine fuel(AVTUR),in the range of10 mgkg to 150 mg
4、kg.NOTE1Specifications falling within the scope of this test method are:Specification D1655 and Defence Standard 91-91.NOTE2This test method detects all FAME components,with peak IRabsorbance at approximately 1749 cm-1and C8to C22molecules,asspecified in standards such as Specification D6751 and EN
5、14214.Theaccuracy of the method is based on the molecular weight of C16to C18FAME species;the presence of other FAME species with differentmolecular weights could affect the accuracy.NOTE3Additives such as antistatic agents,antioxidants and corrosioninhibitors are measured with the FAME by the FTIR
6、spectrometer.However the effects of these additives are removed by the flow analysisprocessing.NOTE4FAME concentrations from 150 mg/kg to 500 mg/kg,andbelow 10 mg/kg can be measured but the precision could be affected.1.2 The values stated in SI units are to be regarded asstandard.No other units of
7、measurement are included in thisstandard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of
8、 regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Tra
