Designation:D396005(Reapproved 2018)Standard Practice forDetermining Volatile Organic Compound(VOC)Content ofPaints and Related Coatings1This standard is issued under the fixed designation D3960;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.Scope1.1 This practice measures the volatile organic compound(VOC)content of solventborne and waterborne paints andrelated coatings as determined from the quantity of materialreleased from a sample under specified bake conditions andsubtracting exempt volatile compounds and water if present.NOTE1The regulatory definition,under the control of the U.S.EPA,can change.To ensure currency,contact the local air pollution controlagency.1.2 This practice provides a guide to the selection ofappropriate ASTM test methods for the determination of VOCcontent.1.3 Certain organic compounds that may be released underthe specified bake conditions are not counted toward coatingVOC content because they do not participate appreciably inatmospheric photochemical reactions.Such negligibly photo-chemically reactive compounds are referred to,as exemptvolatile compounds in this practice.NOTE2Information on the US EPAdefinition of VOC and a list of thecurrent US EPA approved exempt volatile compounds which have beenused in coatings,are provided in Appendix X3.1.4 VOC content is calculated as a function of(1)thevolume of coating less water and exempt volatile compounds,and(2)the volume of coating solids,and(3)the weight ofcoating solids.1.5 The values stated in SI units are to be regarded asstandard.1.6 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.1.7 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:2D1475 Test Method for Density of Liquid Coatings,Inks,and Related ProductsD2369 Test Method for Volatile Content of CoatingsD2697 Test Method for Volume Nonvolatile Matter in Clearor Pigmented CoatingsD2832 Guide for Determining Volatile and Nonvolatile Con-tent of Paint and Related CoatingsD3792 Test Method for Water Content of Coatings by DirectInjection Into a Gas ChromatographD3925 Practice for Sampling Liquid Paints and RelatedPigmented CoatingsD4017 Test Method for Water in Paints and Paint Materialsby Karl Fischer MethodD4457 Test Method for Determination of Dichloromethaneand 1,1,1-Trichloroethane in Paints and Coatings byDirect Injection into a Gas ChromatographD5095 Test Method for Determination of the NonvolatileContent in Silanes,Siloxanes and Silane-Siloxane BlendsUsed in Masonry Water Repellent TreatmentsD5201 Practice for Calculating Formulation Physical Con-stants of Paints and CoatingsD5403 Test Methods for Volatile Content of Radiation Cur-able MaterialsD6093 Test Method for Percent Volume Nonvolatile Matterin Clear or Pigmented Coatings Using a Helium GasPycnometerD6133 Test Method for Acetone,p-Chlorobenzotrifluoride,1This practice is under the jurisdiction of ASTM Committee D01 on Paint andRelated Coatings,Materials,and Applications and is the direct responsibility ofSubcommittee D01.21 on Chemical Analysis of Paints and Paint Materials.Current edition approved June 1,2018.Published June 2018.Originallyapproved in 1981.Last previous edition approved in 2013 as D3960 05(2013).DOI:10.1520/D3960-05R18.2For 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.1 Methyl Acetate or t-Butyl Acetate Content of Solvent-borne and Waterborne Paints,Coatings,Resins,and RawMaterials by Direct Injection Into a Gas ChromatographD6419 Test Method for Volatile Content of Sheet-Fed andColdset Web Offset Printing InksD6438 Test Method for Ace
