Designation:D822/D822M13Standard Practice forFiltered Open-Flame Carbon-Arc Exposures of Paint andRelated Coatings1This standard is issued under the fixed designation D822/D822M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This practice covers the selection of test conditions foraccelerated exposure testing of coatings and related products infiltered open-flame carbon-arc devices conducted according toPractices G151 and G152.This practice also covers thepreparation of test specimens,the test conditions suited forcoatings,and the evaluation of test results.Table 1 describescommonly used test conditions.1.2 This practice does not cover enclosed carbon-arc expo-sures of paints and related coatings,which is described inPractice D5031/D5031M.Another procedure for exposingthese products is covered by Practice D3361/D3361M,inwhich the specimens are subjected to radiation from anunfiltered open-flame carbon arc that produces shorter wave-lengths and higher levels of short wavelength radiation thanfiltered open-flame or enclosed carbon arcs.1.3 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.1.4 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Documents2.1 ASTM Standards:2D358 Specification for Wood to Be Used as Panels inWeathering Tests of Coatings(Withdrawn 2014)3D523 Test Method for Specular GlossD609 Practice for Preparation of Cold-Rolled Steel Panelsfor Testing Paint,Varnish,Conversion Coatings,andRelated Coating ProductsD610 Practice for Evaluating Degree of Rusting on PaintedSteel SurfacesD659 Method for Evaluating Degree of Chalking of ExteriorPaints(Withdrawn 1990)3D660 Test Method for Evaluating Degree of Checking ofExterior PaintsD662 Test Method for Evaluating Degree of Erosion ofExterior PaintsD714 Test Method for Evaluating Degree of Blistering ofPaintsD772 Test Method for Evaluating Degree of Flaking(Scal-ing)of Exterior PaintsD823 Practices for Producing Films of Uniform Thicknessof Paint,Varnish,and Related Products on Test PanelsD1005 Test Method for Measurement of Dry-Film Thick-ness of Organic Coatings Using MicrometersD1186 Test Methods for Nondestructive Measurement ofDry Film Thickness of Nonmagnetic Coatings Applied toa Ferrous Base(Withdrawn 2006)3D1400 Test Method for Nondestructive Measurement of DryFilm Thickness of Nonconductive Coatings Applied to aNonferrous Metal Base(Withdrawn 2006)3D1729 Practice for Visual Appraisal of Colors and ColorDifferences of Diffusely-Illuminated Opaque MaterialsD1730 PracticesforPreparationof AluminumandAluminum-Alloy Surfaces for PaintingD2244 Practice for Calculation of Color Tolerances andColor Differences from Instrumentally Measured ColorCoordinatesD2616 Test Method for Evaluation of Visual Color Differ-ence With a Gray ScaleD3361/D3361M PracticeforUnfilteredOpen-Flame1This practice is under the jurisdiction of ASTM Committee D01 on Paint andRelated Coatings,Materials,and Applications and is the direct responsibility ofSubcommittee D01.27 on Accelerated Testing.Current edition approved Oct.1,2013.Published October 2013.Originallyapproved in 1945.Last previous edition approved in 2006 as D822 01(2006).DOI:10.1520/D0822_D0822M-13.2For 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 last approved version of this historical standard is referenced onwww.astm.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 Carbon-Arc Exposures of Paint and Related CoatingsD4214 Test Methods for Evaluating the Degree of Chalkingof Exterior Paint FilmsD5031/D5031M Practice for Enclosed Carbon-Arc Expo-sure Tests of Paint and Related CoatingsD5870 Practice for Calculating Property Retention Index ofPlasticsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodE1347 Test Method for Color and Color-Difference Mea-surement by Tristimulus ColorimetryG113 Terminology Relating to Natural and Artifici
