Designation:D1006/D1006M21Standard Practice forConducting Exterior Exposure Tests of Hand and FactoryApplied Paints on Wood and Wood Composite Materials1This standard is issued under the fixed designation D1006/D1006M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.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 procedures to be followed for directexposure of house and trim paints on new,previously un-painted wood and wood composite materials to the environ-ment.When originators of a weathering test have the actualexposure conducted by a separate agency,the specific condi-tions for the exposure of test and control specimens should beclearly defined and mutually agreed upon between all parties.1.2 This standard covers specimen preparation including theapplication of the test paint to the wood substrate.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system are not necessarily exact equivalents;therefore,toensure conformance with the standard,each system shall beused independently of the other,and values from the twosystems shall not be combined.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:2D523 Test Method for Specular GlossD660 Test Method for Evaluating Degree of Checking ofExterior PaintsD661 Test Method for Evaluating Degree of Cracking ofExterior PaintsD714 Test Method for Evaluating Degree of Blistering ofPaintsD772 Test Method for Evaluating Degree of Flaking(Scal-ing)of Exterior PaintsD2244 Practice for Calculation of Color Tolerances andColor Differences from Instrumentally Measured ColorCoordinatesD4214 Test Methods for Evaluating the Degree of Chalkingof Exterior Paint FilmsD5237 Guide for Evaluating Fabric SoftenersD6132 Test Method for Nondestructive Measurement of DryFilm Thickness of Applied Organic Coatings Using anUltrasonic Coating Thickness GageD7787 Practice for Selecting Wood Substrates for Weather-ing Evaluations of Architectural CoatingsE122 Practice for Calculating Sample Size to Estimate,WithSpecified Precision,the Average for a Characteristic of aLot or ProcessE1677 Specification forAir Barrier(AB)Material orAssem-blies for Low-Rise Framed Building WallsG7 Practice for Atmospheric Environmental Exposure Test-ing of Nonmetallic MaterialsG113 Terminology Relating to Natural and Artificial Weath-ering Tests of Nonmetallic MaterialsG147 Practice for Conditioning and Handling of Nonmetal-lic Materials for Natural and Artificial Weathering Tests3.Terminology3.1 DefinitionsThe definitions given in Terminology G113are applicable to this practice.3.2 Definitions of Terms Specific to This Standard:3.2.1 rainscreen,na system of construction where thesiding stands off from the moisture-resistant surface of abuilding wall,creating an air gap to allow drainage andventilation.1This 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 1,2021.Published June 2021.Originallyapproved in 1951.Last previous edition approved in 2013 as D1006/D1006M 13.DOI:10.1520/D1006_D1006M-21.2For 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.14.Significance and Use4.1 The procedure described in this practice is intended toaid in evaluating the performance of house and trim paints tonew,previously unpainted woo
