Designation:E278010Standard Test Method forDetermining Particulate Matter Emissions from WoodHeaters1This standard is issued under the fixed designation E2780;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 covers the fueling and operatingprotocol for determining particulate matter emissions fromwood fires in wood-burning room heaters and fireplace insertsas well as determining heat output and efficiency.1.2 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.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.2.Referenced Documents2.1 ASTM Standards:2E631 Terminology of Building ConstructionsE2515 Test Method for Determination of Particulate MatterEmissions Collected by a Dilution Tunnel2.2 Other Standards:ANSI/UL-103 Standard for Chimneys,Factory-Built,Resi-dential Type and Building Heating ApplianceCSA B415.1 Performance Testing of Solid-Fuel-BurningHeating Appliances3.Terminology3.1 DefinitionsTerms used in this test method are definedin Terminology E631.3.2 Definitions of Terms Specific to This Standard:3.2.1 burn rate,nthe rate at which test fuel is consumed ina wood heater.Measured in kilograms(lb)(dry basis)per hour.3.2.2 combustion air control,nan air control device thatregulates air to the wood heater that is primarily intendedpromote pyrolysis of the fuel load.3.2.3 Douglas fir,nuntreated,standard,or better gradeDouglas fir lumber with agency grade stamp:D.Fir or DouglasFir.3.2.4 firebox,nthe chamber in the wood heater in whichthe test fuel charge is placed and combusted.3.2.5 fuel piece,n2 4 or 4 4 wood pieces used toconstruct test fuel cribs and referring to the nominal width anddepth dimensions for commonly available dimensional lumber.The actual dimensions are 38 89 mm(112 312in.)and 89 89 mm(312 312in.).3.2.6 fuel piece length,nthe length of fuel pieces used toconstruct the test fuel crib measured in mm(in.).3.2.7 firebox height,nunless otherwise specified in themanufacturers written instructions included with the heater,firebox height is the vertical distance extending above theloading door,if fuel could reasonably occupy that space,butnot more than 2 inches above the top(peak height)of theloading door,to the floor of the firebox(i.e.,below a permanentgrate)if the grate allows a 1-inch diameter piece of wood topass through the grate,or,if not,to the top of the grate.Fireboxheight is not necessarily uniform but must account for varia-tions caused by internal baffles,air channels,or other perma-nent obstructions.A visible indicator or landmark within thefirebox that will provide a clear indication to the heater user ofthe maximum height that fuel should be loaded,and isspecificallyreferencedinthemanufacturerswritteninstructions,may be used to determine firebox height for thepurposes of calculating usable firebox volume.3.2.8 firebox length,nthe longest horizontal fire chamberdimension where fuel pieces might reasonably be expected tobe placed in accordance with the manufacturers writteninstructions that is parallel to a wall of the chamber.3.2.9 firebox width,nthe shortest horizontal fire chamberdimension where fuel pieces might reasonably be expected tobe placed in accordance with the manufacturers writteninstructions that is parallel to a wall of the chamber.1This test method is under the jurisdiction of ASTM Committee E06 onPerformance of Buildings and is the direct responsibility of Subcommittee E06.54on Solid Fuel Burning Appliances.Current edition approved Oct.1,2010.Published December 2010.DOI:10.1520/E2780-10.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.10 kindling,nwood pieces used to initiate combustionof the pre-burn fuel.Kindling may be ignited using crumplednewspaper.3.2.11 manufacturers written instructions,nspecific in-formation regarding the fueling and operation proceduresrecommended by the heater manufacturer and included withthe heater.These instructions must be consistent with informa-tion provided to the heater end-user in the owners manual orequivalent.3.2.12 owners manual,nwritten information provided tothe heater end-user regarding the installation and recom-mended fueling and operating procedures that will help
