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,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 impurities 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 directly at the fuelingstation or on an extracted sample that is sent to be analyzedelsewhere.Multiple contaminants can be measured simultane-ously as long as they are in the gaseous phase and absorb in theinfrared wavelength region.The detection limits as well asspecific target contaminants for this standard 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 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 extendedto other impurities provided that they are in the gaseous phaseor can 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 industrial 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 metering 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 sample 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,(3)the determination of theminimum detectable concentration for each impurity species asmeasured on 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 appropriate SI unit will beincluded in parenthesis after the common value usage.(4.4,7.8,7.9,10.5,and 11.6)1.8 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D5287 Practice for Automatic Sampling of Gaseous FuelsD6348 Test Method for Determination of Gaseous Com-pounds by Extractive Direct Interface Fourier TransformInfrared(FTIR)SpectroscopyD7606 Practice for Sampling of High Pressure Hydrogenand Related Fuel Cell Feed Gases2.2 SAE Document:3SAE TIR J2719 Informational Report on the Developmentof a Hydrogen Quality Guideline for Fuel Cell Vehicles1This test method is under the jurisdiction ofASTM Committee D03 on GaseousFuels and is the direct responsibility of Subcommittee D03.14 on Hydrogen andFuel Cells.Current edition approved Sept.1,2010.Published March 2011.DOI:10.1520/D765310.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from SAE International(SAE),400 Commonwealth Dr.,Warrendale,PA 15096-0001,http:/www.sae.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.3 EPA Documents4EPA 40 CFR Protection of the Environment,Appendix B toPart 136 Definition and Procedure for the Determinationof the Method Detection Limit.EPA 40 CFR Protection of the Environment
