Designation:D1669/D1669M07(Reapproved 2013)1Standard Practice forPreparation of Test Panels for Accelerated and OutdoorWeathering of Bituminous Coatings1This standard is issued under the fixed designation D1669/D1669M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEUnits information was editorially corrected in July 2013.1.Scope1.1 This practice covers a procedure for the preparation ofaccelerated and outdoor weathering test panels of bituminouscoatings.It is considered suitable for the preparation of filmthicknesses in the range from 0.25 to 2.54 mm 0.010 to 0.100in.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.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.(WarningMercury has been designated by EPA and many state agenciesas a hazardous material that can cause central nervous system,kidney,and liver damage.Mercury,or its vapor,may behazardous to health and corrosive to materials.Caution shouldbe taken when handling mercury and mercury-containingproducts.See the applicable product Material Safety DataSheet(MSDS)for details and EPAs website,http:/www.epa.gov/mercury/faq.htm,for additional information.Us-ers should be aware that selling mercury or mercury-containingproducts,or both,into your state may be prohibited by statelaw.)2.Referenced Documents2.1 ASTM Standards:2B209 Specification for Aluminum and Aluminum-AlloySheet and PlateD5 Test Method for Penetration of Bituminous MaterialsE1 Specification for ASTM Liquid-in-Glass Thermometers3.Summary of Practice3.1 Heated bituminous material is poured onto a clean,heated,and masked aluminum panel.Care is taken to removeair bubbles.The bitumen is leveled in a press beforesolidifying,and the coated panel is then cooled,cleaned,andmeasured for uniform thickness.4.Significance and Use4.1 This practice for preparation of test panels greatlyincreases the likelihood of achieving reproducible results insubsequent testing.5.Apparatus5.1 PanelA supporting metal panel on which the bitumi-nous coating is applied.It shall meet the following require-ments:5.1.1 Metal,Aluminum or Aluminum Alloy,as described inTable 2 of Specification B209 under Alloy 3003-H14.35.1.2 FinishMill finish and process cleaned.5.1.3 Dimensions:5.1.3.1 Thickness0.64 to 1.90 mm 0.025 to 0.075 in.5.1.3.2 Width and Length70 by 150 mm 234by 578in.or of a size that will allow a minimum bitumen film area of 50by 130 mm 2 by 518in.1This practice is under the jurisdiction ofASTM Committee D08 on Roofing andWaterproofing and is the direct responsibility of Subcommittee D08.02 on SteepRoofing Products and Assemblies.Current edition approved July 1,2013.Published July 2013.Originally approvedin 1959.Last previous edition approved in 2013 as D1669 07(2013).DOI:10.1520/D1669_D1669M-07R13E01.2For 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.3The sole sources of supply of the apparatus(panels)known to the committee atthis time are The Q-Panel Company,26200 First St.,Cleveland OH 44145;AtlasElectric Devices Co.,4114 N.Ravenswood Ave.,Chicago,IL 60613;AdvancedCoating Technologies Inc.,273 Industrial Dr.(PO Box 401),Hillsdale MI 49242.If you are aware of alternative suppliers,please provide this information to ASTMInternational Headquarters.Your comments will receive careful consideration at ameeting of the responsible technical committee,1which you may attend.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.1.4 FlatnessThe maximum deviation from a true flatsurface for either length or width shall not exceed 0.0005 timesthe dimension.Flatness shall be measured on a true flat surfaceemploying a curling gauge equipped with a dial which reads in0.025 mm 0.001 in.and having a foot loading of approxi-mately 100 g.45.1.5 EdgesThe edges of the panels shall be free of burrs.5.1.6 StoragePanels shall be stored in a dry,well-ventilated place to prevent condensation and possible stainingor corrosion.5.2 PressThe press shall be capable of delivering a4500-kg 10 000-lb thrust and be equipped for using platens152 by 152 mm 6 by 6 in.or larger platens.55.3
