1、Designation:D765310Standard Test Method forDetermination of Trace Gaseous Contaminants in HydrogenFuel by Fourier Transform Infrared(FTIR)Spectroscopy1This standard is issued under the fixed designation D7653;the number immediately following the designation indicates the year oforiginal adoption or,
2、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 employs an FTIR gas analysis systemfor the determination of trace impu
3、rities in gaseous hydrogenfuels relative to the hydrogen fuel quality limits described inSAE TIR J2719(April 2008)or in hydrogen fuel qualitystandards from other governing bodies.This FTIR method isused to quantify gas phase concentrations of multiple targetcontaminants in hydrogen fuel either direc
