Designation:D676308(Reapproved 2014)Standard Guide forTesting Exterior Wood Stains and Clear Water Repellents1This standard is issued under the fixed designation D6763;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 guide covers the selection and use of proceduresfor testing exterior wood stains and clear water repellents.Thisincludes both water borne and solvent borne semitransparentand opaque stains and clear water repellents.The propertiesthat can be examined or,in some cases,the relevant testprocedures are listed in 2.1 and 2.2.NOTE1The term“opaque stain”is defined as a pigmented composi-tion intended for use on wooden surfaces to produce a uniform finish thatobscures the grain and color of the wood,but not its surface texture;alsocalled solid color or solid hide.NOTE2The term“semitransparent”is defined as a pigmentedcomposition intended for use on wooden surfaces to produce a uniformfinish that does not fully obscure the grain or the texture of the wood.NOTE3The term“clear”is defined as a transparent compositionintended for use on wooden surfaces to produce a uniform finish that doesnot obscure the grain or texture of the wood.1.1.1 DiscussionWhen applied to woods that differ incolor,there is a color difference between stained substrates.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard may involve hazardous materials,operations,and equipment.This standard does not purport toaddress all of the safety concerns,if any,associated with itsuse.It is the responsibility of the user of this standard toestablish appropriate safety and health practices and deter-mine the applicability of regulatory requirements prior to use.2.Referenced Documents2.1 ASTM Standards:2D16 Terminology for Paint,Related Coatings,Materials,andApplicationsD56 Test Method for Flash Point by Tag Closed Cup TesterD93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD154 Guide for Testing VarnishesD185 Test Methods for Coarse Particles in PigmentsD215 Practice for the Chemical Analysis of White LinseedOil Paints(Withdrawn 2005)3D344 Test Method for Relative Hiding Power of Paints bythe Visual Evaluation of BrushoutsD358 Specification for Wood to Be Used as Panels inWeathering Tests of Coatings(Withdrawn 2014)3D522 Test Methods for Mandrel Bend Test of AttachedOrganic CoatingsD523 Test Method for Specular GlossD562 Test Method for Consistency of Paints MeasuringKrebs Unit(KU)Viscosity Using a Stormer-Type Viscom-eterD660 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 PaintsD869 Test Method for Evaluating Degree of Settling of PaintD968 Test Methods for Abrasion Resistance of OrganicCoatings by Falling AbrasiveD1006 Practice for Conducting Exterior Exposure Tests ofPaints on WoodD1038 Terminology Relating to Veneer and PlywoodD1210 Test Method for Fineness of Dispersion of Pigment-Vehicle Systems by Hegman-Type GageD1296 Test Method for Odor of Volatile Solvents andDiluentsD1475 Test Method For Density of Liquid Coatings,Inks,and Related ProductsD1554 Terminology Relating to Wood-Base Fiber and Par-ticle Panel Materials1This guide is under the jurisdiction of ASTM Committee D01 on Paint andRelated Coatings,Materials,and Applications and is the direct responsibility ofSubcommittee D01.42 on Architectural Coatings.Current edition approved Sept.15,2014.Published September 2014.Originallyapproved in 2002.Last previous edition approved in 2008 as D6763 08.DOI:10.1520/D6763-08R14.2For 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 D1640 Test Methods for Drying,Curing,or Film Formationof Organic Coatings at Room TemperatureD1729 Practice for Visual Appraisal of Colors and ColorDifferences of Diffusely-Illuminated Opaque MaterialsD1849 Test Method for Package Stability of PaintD2196 Test Methods for Rheological Properties of Non-Newtonian Materials by Rotational(Brookfield type)ViscometerD2197 Test Method for Adhesion of Organic Coatings byScrape Adhesion
