Designation:D458711(Reapproved 2019)1Standard Practice forFluorescent UV-Condensation Exposures of Paint andRelated Coatings1This standard is issued under the fixed designation D4587;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.1NOTESection 4.2 was updated editorially in December 2019.1.Scope1.1 This practice covers the selection of test conditions foraccelerated exposure testing of coatings and related products influorescent UV and condensation devices conducted accordingto Practices G151 and G154.This practice also covers thepreparation of test specimens,and the evaluation of test results.Table 1 describes commonly used test conditions.NOTE1Previous versions of this practice referenced fluorescent UVdevices described by Practice G53,which described very specific equip-ment designs.Practice G53 has been withdrawn and replaced by PracticeG151,which describes performance criteria for all exposure devices thatuse laboratory light sources,and by Practice G154,which gives require-ments for exposing nonmetallic materials in fluorescent UV devices.NOTE2ISO 11507:1997 also describes fluorescent UV-condensationexposures of paints and coatings.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.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Documents2.1 ASTM Standards:2D358 Specification for Wood to Be Used as Panels inWeathering Tests of Coatings(Withdrawn 2014)3D523 Test Method for Specular GlossD609 Practice for Preparation of Cold-Rolled Steel Panelsfor Testing Paint,Varnish,Conversion Coatings,andRelated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,Coatings 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 a1This 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 Dec.1,2019.Published December 2019.Originallyapproved in 1986.Last previous edition approved in 2011 as D4587 11.DOI:10.1520/D4587-11R19E01.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.Nonferrous 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 Rating Adhesion by Tape TestD3980 Practice for Interlaboratory Testing of Paint andRelated Materials(Withdrawn 1998)3D4214 Test Methods for E
