Designation:D765117Standard Test Method forGravimetric Measurement of Particulate Concentration ofHydrogen Fuel1This standard is issued under the fixed designation D7651;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 is primarily intended for gravimetricdetermination of particulate concentration in hydrogen in-tended as a fuel for fuel cell or internal combustion enginepowered vehicles.This test method describes operating andquality control procedures required to obtain data of knownquality satisfying the requirements of SAE J2719.This testmethod can be applied to other gaseous samples requiringdetermination of particulates provided the users data qualityobjectives are satisfied.1.2 The values stated in SI units are to be regarded asstandard.No other units of 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 and health practices and determine the applica-bility of 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 Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D4150 Terminology Relating to Gaseous FuelsD7650 Test Method for Sampling of Particulate Matter inHigh Pressure Hydrogen used as a Gaseous Fuel with anIn-Stream FilterE617 Specification for Laboratory Weights and PrecisionMass Standards2.2 SAE Standards:3SAE J2600 Compressed Hydrogen Surface Vehicle Refuel-ing Connection DevicesSAE J2719 Hydrogen Quality Guideline for Fuel Cell Ve-hicles2.3 Other Standards:Code of Federal Regulations,Title 40,Part 50,Appendix L,Section 8.24ISO 146872 Hydrogen fuel-Product specification-Part2:Proton exchange membrane(PEM)fuel cell applica-tions for road vehicles53.Terminology3.1 Acronyms:3.1.1 FCVHydrogen Fuel Cell Vehicle3.1.2 HEPAHigh Efficiency Particulate Air3.1.3 PEMPolymer Electrolyte Membrane,also calledProton Exchange Membrane3.1.4 PEMFCProton Exchange Membrane Fuel Cell3.1.5 PTFEPolytetrafluoroethylene3.1.6 SAESAE International3.2 Definitions:For definitions of general gaseous fuelterms used in this practice,refer to D4150.3.2.1 weight monitoring filter,WMFThis filter is putinside the glove box or clean room(7.3)with the balance(7.1)and never removed.The weight of this filter is alwaysmeasured before and after each measurement event.4.Summary of Test Method4.1 This test method is used to determine the concentrationof particulate matter and nonvolatile reside on filters collectedfrom hydrogen fuel or other gaseous streams at fueling station1This 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 Nov.1,2017.Published December 2017.Originallyapproved in 2010.Last previous edition approved in 2010 as D765110.DOI:10.1520/D765117.2For 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.4Available from Office of the Federal Register,800 N.Capitol St.,NW Suite 700Washington,DC 20001.5Available from International Organization for Standardization(ISO),1,ch.dela Voie-Creuse,Case postale 56,CH-1211,Geneva 20,Switzerland,http:/www.iso.ch.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 dispenser nozzles(Test Method D7650,SAE J2600)or othergaseous fuel delivery system dispenser interfaces.The particu-late concentration is determined by dividing the particulateweight,which is the difference of filter weights before and aftersampling,by the total volume of hydrogen or other gaseousfuels passing through the filter.Every precaution should betaken to avoid contamination of particulates onto the filtercoming from the particulate sampling adapter,the analyticalsystem,ambient air,filter handling,or other environmentalsour
