  • Component CertificationMonitoring & Laboratory DivisionLaMar MitchellPat BennettJim Watson

  • Component CertificationWhat is component certification?Component certification is the certification of fuel hoses, fuel tanks, and carbon canisters by ARB.Certification means that the manufacturers have demonstrated that their product meets applicable design requirements.

  • Component CertificationHow is component certification useful?Allows engine and equipment manufacturers to reference a component Executive Order (EO) in a certification application when certifying by designMultiple OEMs can rely on same component EOExpedites certification process by eliminating the need to review component compliance data

  • Component Certification(How it works) Tank is Certified by Component Manf.Certified Components will be Listed on theSORE Web Page Hose is Certified by Component Manf.Canister is Certified by Component Manf.Engine/Equipment Manf.References Components on Certified ListARB Certifies Engine/EquipmentUsing Component EOsin Lieu of Component Data

  • Component CertificationWho is expected to apply for a component EOFuel hose manufacturers like Goodyear, Teleflex, Mark IV, and Mold-Ex, Inc.Fuel tank manufacturers like Kelch Corp., Honeywell Plastics, and Mergon Corp. Carbon canister manufacturers like MPC, Eaton Corp., Delphi Automotive, and Sentec E&E

  • Component Certification ProcessManufacturer tests a minimum of 5 samples of component using applicable test procedureFuel hose - SAE J1737 (allowable test fuels and test temperatures specified in 13 CCR 2754) Fuel tank - TP-901Carbon canister - TP-902Alternative test procedures must be approved by ARB in advance.

  • Component Certification Process Components Tested Fuel hose - smallest inside diameter Fuel Tank - smallest volume to surface area ratio Carbon canister - canister sized for the largest fuel tank

  • Component Certification ProcessManufacturer submits letter with test data requesting a component EO to:

    California Air Resources BoardMonitoring and Laboratory DivisionAttn: Division ChiefP.O. Box 2815Sacramento, CA 95812

  • Component Certification ProcessLetter, on company letterhead must include:Emissions data from 5 component samplesReference to the test procedure used to generate the dataLetter signed by authorized company representative

  • Component Certification Process Letter should also include: General description of material composition Drawing of component Installation and maintenance instructions (if applicable) Limits for proper functioning Sample of untested component or coupon for tanks

  • Component Certification Process FlowchartComponent Manf. Tests ComponentComponent Manf. Submits Letterwith Data to ARBARB Reviews LetterFor CompletenessARB Issues Component EOand Adds Component to Certified ListARB Requests Further Info. From ManufacturerWithin 30 DaysARB Mails EOto ManufacturerYesNoWithin 90 daysARB Approves or Denies Component EOApproves EODenies EOARB Mails denial letterto Manufacturer

  • Component Certification Process(Fuel Hose Case Study)Example:

    A manufacturer seeks a component EO for low permeation fuel hoses with internal diameters ranging in size from 1/4 to 3/8 inches

  • Component Certification Process(Fuel Hose Case Study)To obtain a component EO, a manufacturer would:

    Generate fuel hose permeation data for the fuel hose with smallest inside diameter within the production range

    Test five samples of hose following SAE J1737

    Test must be conducted at 40C or higher with CERT fuel, Indolene, CE10, or CM15

  • Component Certification Process(Fuel Hose Case Study)

    Submit a letter to ARB requesting a component EO which includes:hose emissions data from five samplesa declaration of how the test data was generated (hose was tested at a constant 40C with CE10 following SAE J 1737)a signature by authorized company representative

  • Component Certification Process(Fuel Hose Case Study, continued)general material description of the hose with CAD drawingan untested sample hoselocation and mounting instructionsany conditions which might affect the hoses integrity (maximum skin temperature, kinking radius, etc.)

  • Component Certification Process(Fuel Hose Case Study)After receiving the request, ARB processes the certification application by:

    Logging the date of receipt

    Reviewing the application for completeness

    Notifying applicant

  • Component Certification Process(Fuel Hose Case Study)Verifying that all data points are below the design criteria of 15 grams/meter2/day

    Drafting a component EO for the hoses

    Mailing the component EO to the manufacturer

    Adding the component EO to Sore Web Page

  • Evaporative Certification GuidanceKeith Macias

  • Evaporative EmissionsCertification GuidanceGeneral InformationObtain a manufacturer code from the U.S. EPA, through the following Website:

    www.epa.gov/OMSWWW/cfeis.htm

  • Evaporative EmissionsCertification GuidanceGeneral Information

    Manufacturer contact personsDesignate 1 or 2 authorized representatives

    ARB contact personARB will assign a primary certification contact person for certification assistance

  • Evaporative EmissionsCertification GuidanceGeneral Information

    Executive Order must be obtained prior to saleThe following items may be submitted prior to the certification application for ARB approval:Evaporative emission control warranty statementEvaporative emission equipment labelAlternative test procedures

  • Evaporative EmissionsCertification Guidance for EnginesLess Than or Equal to 80 cc

  • Regulations and GuidanceTitle 13, CCR, Sections 2750 to 2773The engine exhaust family is the evaporative family [www.arb.ca.gov/msprog/offroad/sore/sore.htm] CP 901 (Certification Procedures) [www.arb.ca.gov/regact/sore03/cp901.pdf]TP 901 (Test Procedure) [www.arb.ca.gov/regact/sore03/tp901.pdf]Certification guidelines (guidance and examples) [weblink to be posted]

  • ApplicabilityThe evaporative standards apply to gasoline fueled small spark-ignited engines.Implementation date: 2007 Model Year Only the fuel tank is required to meet permeation standardsThese standards do not apply to CI engines or engines powered by the following fuels:CNGPropaneLPGLNG

  • Certification OptionsPermeation Emission StandardsData from fuel tank permeation that exhibits the highest evaporative emissions.Typically, the worst case tank is the one with the least tank volume to internal surface area ratio.May certify to cleaner emissions standard (Blue Sky)

  • Certification OptionsExemptionMay certify by meeting the exemption requirements of 2766.submit a letter of conformancesubmit certification application less emission test data

  • Certification OptionsInnovative ProductMust apply to MLD.Upon approval, MLD will provide an EO number.Submit application with EO number.

  • Data Carryover and CarryacrossMay Carryover emission data from the previous model yearSame material processNo changes to emission control systemMay Carryacross emission data from one evaporative family to another Must be representative of new familySubject to ARB Approval
