Designation:D342411Standard Practice forEvaluating the Relative Lightfastness and Weatherability ofPrinted Matter1This standard is issued under the fixed designation D3424;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 standard describes procedures for the determina-tion of the relative lightfastness and weatherability of printedmatter under the following conditions,which involve exposureto natural daylight or accelerated procedures in the laboratory:1.1.1 Method 1Daylight behind window glass,1.1.2 Method 2Outdoor weathering,1.1.3 Method 3Xenon-arc apparatus with window glassfilters to simulate daylight behind window glass,1.1.4 Method 4Xenon-arc apparatus with water spray anddaylight filters to simulate outdoor weathering,1.1.5 Method 7Fluorescent lamp apparatus to simulateindoor fluorescent lighting in combination with window-filtered daylight.1.1.6 Method 8Fluorescent lamp apparatus operating withfluorescent cool white lamps to simulate indoor fluorescentlighting.NOTE1Previous versions of this standard included Methods 5 and 6that are based on enclosed carbon-arc exposures.These methods aredescribed in Appendix X1.The spectral irradiance of the enclosedcarbon-arc is a very poor simulation of solar radiation,window glassfiltered solar radiation,or the emission of lamps used for interior lighting.In addition,enclosed carbon-arc devices are no longer readily available orcommonly used.1.2 These methods require that a suitable print or othercontrol(reference standard)be run along with the test sample.Color changes due to conditions of exposure may be evaluatedby visual examination or instrumental measurement.1.3 These methods are applicable to prints on any flatsubstrate including paper,paperboard,metallic foil,metalplate,and plastic film,and are produced by any printingprocess including letterpress,offset lithography,flexography,gravure,and silk screen.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 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.For specific hazardstatements,see Section 8.2.Referenced Documents2.1 ASTM Standards:2D1729 Practice for Visual Appraisal of Colors and ColorDifferences of Diffusely-Illuminated Opaque MaterialsD2244 Practice for Calculation of Color Tolerances andColor Differences from Instrumentally Measured ColorCoordinatesD2616 Test Method for Evaluation of Visual Color Differ-ence With a Gray ScaleD4302 Specification for Artists Oil,Resin-Oil,and AlkydPaintsD4674 Practice forAccelerated Testing for Color Stability ofPlastics Exposed to Indoor Office EnvironmentsD5067 Specification for Artists Watercolor PaintsD5098 Specification for Artists Acrylic Dispersion PaintsE284 Terminology of AppearanceE991 Practice for Color Measurement of Fluorescent Speci-mens Using the One-Monochromator MethodE1331 Test Method for Reflectance Factor and Color bySpectrophotometry Using Hemispherical GeometryE1347 Test Method for Color and Color-Difference Mea-surement by Tristimulus ColorimetryE1349 Test Method for Reflectance Factor and Color bySpectrophotometry Using Bidirectional(45:0 or 0:45)GeometryG7 Practice for Atmospheric Environmental Exposure Test-ing of Nonmetallic MaterialsG24 Practice for Conducting Exposures to Daylight FilteredThrough GlassG113 Terminology Relating to Natural and Artificial Weath-ering Tests of Nonmetallic Materials1This practice is under the jurisdiction of ASTM Committee D01 on Paint andRelated Coatings,Materials,and Applications and are the direct responsibility ofSubcommittee D01.56 on Printing Inks.Current edition approved Feb.1,2011.Published February 2011.Originallyapproved in 1975.Last previous edition approved in 2009 as D3424 09.DOI:10.1520/D3424-11.2For 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.*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 G151 Practice for Exposing Nonmetallic Materials inAccel-erated Test Devices that Use Laboratory Light SourcesG153 Practice for Operating Enclosed Carbon Arc LightApparatus for Exposure of Nonmetallic MaterialsG154 Practice for Operating Fluorescent Ultraviolet(UV)Lamp Apparatus for Exposure of Nonmetallic MaterialsG155 Practice for Operating Xenon Ar
