Designation:D101418Standard Practice forConducting Exterior Exposure Tests of Paints and Coatingson Metal Substrates1This standard is issued under the fixed designation D1014;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This practice covers procedures to be followed for directexposure of exterior paints and coatings to the environmentwhen applied to metal surfaces.When originators of a weath-ering test have the actual exposure conducted by a separateagency,the specific conditions for the exposure of test andcontrol specimens should be clearly defined and mutuallyagreed upon between all parties.1.2 Experience indicates that the metal used as a testsubstrate has a significant effect upon weathering results.Thepurpose of this practice is to define specific steel and othermetal surfaces to be used for testing in order to minimize thissource of variability.1.3 The values stated in SI units are to be regarded as thestandard.The values given in parenthesis are for informationonly.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 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:2A36/A36M Specification for Carbon Structural SteelA283/A283M Specification for Low and Intermediate Ten-sile Strength Carbon Steel PlatesB209 Specification for Aluminum and Aluminum-AlloySheet and PlateB449 Specification for Chromates on AluminumD523 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 SurfacesD660 Test Method for Evaluating Degree of Checking ofExterior PaintsD661 Test Method for Evaluating Degree of Cracking 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 PanelsD1212 Test Methods for Measurement of Wet Film Thick-ness of Organic CoatingsD1654 Test Method for Evaluation of Painted or CoatedSpecimens Subjected to Corrosive EnvironmentsD1729 Practice for Visual Appraisal of Colors and ColorDifferences of Diffusely-Illuminated Opaque MaterialsD1730 PracticesforPreparationof AluminumandAluminum-Alloy Surfaces for PaintingD2200 Practice for Use of Pictorial Surface PreparationStandards and Guides for Painting Steel SurfacesD2201 Practice for Preparation of Zinc-Coated and Zinc-Alloy-Coated Steel Panels for Testing Paint and RelatedCoating ProductsD2244 Practice for Calculation of Color Tolerances andColor Differences from Instrumentally Measured ColorCoordinatesD2616 Test Method for Evaluation of Visual Color Differ-ence With a Gray Scale1This 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 April 1,2018.Published April 2018.Originallyapproved in 1949.Last previous edition approved in 2009 as D1014 09 which waswithdrawn January 2018 and reinstated in April 2018.DOI:10.1520/D1014-18.2For 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 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.1 D2803 Guide for Testing Filiform Corrosion Resistance ofOrganic Coatings on MetalD3359 Test Methods for Rating Adhesion by Tape TestD4214 Test Methods fo
