Designation:D669508Standard Practice forXenon-Arc Exposures of Paint and Related Coatings1This standard is issued under the fixed designation D6695;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 practice covers the selection of test conditions foraccelerated exposure testing of coatings and related products inxenon arc devices conducted according to Practices G151 andG155.This practice also covers the preparation of testspecimens,the test conditions suited for coatings,and theevaluation of test results.Table 1 describes commonly used testconditions.NOTE1ISO 11341 also describes xenon-arc exposures of paints andcoatings.However,the exposure conditions described in ISO 11341 aredifferent than those listed in Table 1.1.2 The values SI units are to be regarded as standard.Thevalues given in parentheses are for information only.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Documents2.1 ASTM Standards:2D358 Specification for Wood to Be Used as Panels inWeathering Tests of Coatings(Withdrawn 2014)3D523 Test Method for Specular GlossD609 Practice for Preparation of Cold-Rolled Steel Panelsfor Testing Paint,Varnish,Conversion Coatings,andRelated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Evaluating Degree of Rusting on PaintedSteel SurfacesD659 Method for Evaluating Degree of Chalking of ExteriorPaints(Withdrawn 1990)3D660 Test Method for Evaluating Degree of Checking ofExterior PaintsD662 Test Method for Evaluating Degree of Erosion ofExterior PaintsD714 Test Method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Test Methods for Nondestructive Measurement ofDry Film Thickness of Nonmagnetic Coatings Applied toa Ferrous Base(Withdrawn 2006)3D1400 Test Method for Nondestructive Measurement of DryFilm Thickness of Nonconductive Coatings Applied to aNonferrous Metal Base(Withdrawn 2006)3D1729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 ScaleD3359 Test Methods for Measuring Adhesion by Tape TestD3980 Practice for Interlaboratory Testing of Paint andRelated Materials(Withdrawn 1998)3D4214 Test Methods for Evaluating the Degree of Chalkingof Exterior Paint FilmsD5870 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 Artificial Weath-ering Tests of Nonmetallic MaterialsG141 Guide for Addressing Variability in Exposure Testingof Nonmetallic MaterialsG147 Practice for Conditioning and Handling of Nonmetal-lic Materials for Natural and Artificial Weathering Tests1This 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 June 1,2008.Published July 2008.Originally approvedin 2001.Last previous edition approved in 2003 as D6695 03a.DOI:10.1520/D6695-08.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 G151 Practice for Exposing Nonmetallic Materials inAccel-erated Test Devices that Use Laboratory Light SourcesG155 Practice for Operating Xenon Arc Light Apparatus forExposure of Non-Metallic MaterialsG169 Guide for Application of Basic Statistical Methods toWeathering Tests2.2 ISO Standards:ISO 11341 Paints and VarnishesArtificial Weathering andExposure to Artificial RadiationExposure to FilteredXenon-Arc Radiation42.3 Society of Automotive Engineers Standards:SAE J2412 Accelerated
