1、Designation:D765318Standard 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

5、ndard were selectedbased upon those set forth in SAE TIR J2719.1.2 This test method allows the tester to determine whichspecific contaminants for hydrogen fuel impurities that are inthe gaseous phase and are active infrared absorbers which meetor exceed the detection limits set by SAE TIR J2719 for
6、theirparticular FTIR instrument.Specific target contaminantsinclude,but are not limited to,ammonia,carbon monoxide,carbon dioxide,formaldehyde,formic acid,methane,ethane,ethylene,propane,and water.This test method may be ex-tended to other impurities provided that they are in the gaseousphase or can
7、 be vaporized and are active infrared absorbers.1.3 This test method is intended for analysis of hydrogenfuels used for fuel cell feed gases or for internal combustionengine fuels.This method may also be extended to the analysisof high purity hydrogen gas used for other applicationsincluding industr
8、ial applications,provided that target impuri-ties and required limits are also identified.1.4 This test method can be used to analyze hydrogen fuelsampled directly at the point-of-use from fueling stationnozzles or other feed gas sources.The sampling apparatusincludes a pressure regulator and meteri
9、ng valve to provide anappropriate gas stream for direct analysis by the FTIR spec-trometer.1.5 This test method can also be used to analyze samplescaptured in storage vessels from point-of-use or other sources.Analysis of the stored samples can be performed either in amobile laboratory near the samp
10、le source or in a standardanalytical laboratory.1.6 A test plan should be prepared that includes(1)thespecific impurity species to be measured,(2)the concentrationlimits for each impurity species,and(3)the determination ofthe minimum detectable concentration for each impurity spe-cies as measured on
11、 the apparatus before testing.1.7 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7.1 ExceptionAll values are based upon common termsused in the industry of those particular values and when notconsistent with SI units,the appro
