Designation:D727007(Reapproved 2021)Standard Guide forEnvironmental and Performance Verification of Factory-Applied Liquid Coatings1This standard is issued under the fixed designation D7270;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 provides a generic testing procedure to verifythe air pollution-prevention characteristics and basic propertiesof liquid coatings applied to metal,plastic,wood,or compositesubstrates in a factory/manufacturing environment.Thus itmay be used to evaluate these liquid coatings to verify theirvolatile organic compound(VOC)and organic hazardous airpollutant(HAP)content as well as basic performance proper-ties.1.2 This guide is adapted from a procedure used by the USEnvironmental Protection Agency(EPA)to establish thirdparty verification of the physical properties and performance ofcoatings that have potential to reduce air emissions.The datafrom the verification testing is available on the internet at theEPAs Environmental Technology Verification(ETV)Programwebsite(http:/www.epa.gov/etv/centers/center6.html)underthe“P2 Innovative Coatings and Coating Equipment Pilot.”1.3 The values stated in SI units are to be regarded as thestandard.The values given in parentheses 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:2B117 Practice for Operating Salt Spray(Fog)ApparatusB499 Test Method for Measurement of Coating Thicknessesby the Magnetic Method:Nonmagnetic Coatings onMagnetic Basis MetalsD522 Test Methods for Mandrel Bend Test of AttachedOrganic CoatingsD523 Test Method for Specular GlossD1729 Practice for Visual Appraisal of Colors and ColorDifferences of Diffusely-Illuminated Opaque MaterialsD1735 Practice for Testing Water Resistance of CoatingsUsing Water Fog ApparatusD2244 Practice for Calculation of Color Tolerances andColor Differences from Instrumentally Measured ColorCoordinatesD2369 Test Method for Volatile Content of CoatingsD2794 Test Method for Resistance of Organic Coatings tothe Effects of Rapid Deformation(Impact)D3359 Test Methods for Rating Adhesion by Tape TestD3363 Test Method for Film Hardness by Pencil TestD3792 Test Method for Water Content of Coatings by DirectInjection Into a Gas ChromatographD3960 Practice for Determining Volatile Organic Compound(VOC)Content of Paints and Related CoatingsD4017 Test Method for Water in Paints and Paint Materialsby Karl Fischer MethodD4060 Test Method for Abrasion Resistance of OrganicCoatings by the Taber Abraser1This guide is under the jurisdiction of ASTM Committee D01 on Paint andRelated Coatings,Materials,and Applications and is the direct responsibility ofSubcommittee D01.55 on Factory Applied Coatings on Preformed Products.Current edition approved June 1,2021.Published June 2021.Originallyapproved in 2007.Last previous edition approved in 2013 as D7270 07(2013).DOI:10.1520/D7270-07R21.2For 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.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.1D4457 Test Method for Determination of Dichloromethaneand 1,1,1-Trichloroethane in Paints and Coatings byDirect Injection into a Gas Chromatograph(Withdrawn2019)3D5402 Practice for Assessing the Solvent Resistance ofOrganic Coatings Using Solvent RubsD5767 Test Method for Instrumental Measurement ofDistinctness-of-Image(DOI)Gloss of Coated SurfacesD6133 Test Method for Acetone,p-Chlorobenzotrifluoride,Methyl Acetate or t-Butyl Acetate Content of Solvent-borne and Waterborne Paints,Coatings,Resins,and RawMaterials by Direct Injection Into a Gas ChromatographD6438 Test Method for Acetone,Methyl Acetate,andParachl
