Designation:D33301(Reapproved 2021)Standard Guide forClear and Pigmented Lacquers1This standard is issued under the fixed designation D333;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 These test methods cover procedures for testing lacquersand lacquer coatings.The test methods included are listed inTable 1.NOTE1In accordance with Terminology D16,a lacquer is defined asa coating composition that is based on synthetic thermoplastic film-forming material dissolved in organic solvent(s)and that dries primarilyby solvent evaporation.Typical lacquers include those based onnitrocellulose,other cellulose derivatives,vinyl resins,acrylic resins,etc.NOTE2Lacquers may be applied under such diverse conditions,to somany different surfaces,and their dried films may be subjected to so manykinds of wear and exposure that it is not possible to assure desiredperformance from a single selection of test methods and numerical resultstherefrom.Those skilled in lacquer technology may find partial assuranceof obtaining desired qualities in various types of lacquers through carefulselection of the methods covered herein and intelligent interpretation ofresults therefrom.NOTE3It is intended ultimately to remove all experimental proce-dures from Test Methods D333 and to establish them as a guide to theselection of test methods for lacquer and perhaps to interpretation ofresults therefrom.Temporarily there remain in Test Methods D333 a fewtests that are too short or otherwise presently unsuitable for establishmentunder separate ASTM designations.1.2 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.3 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.1.4 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)ApparatusD16 Terminology for Paint,Related Coatings,Materials,andApplicationsD56 Test Method for Flash Point by Tag Closed Cup TesterD88 Test Method for Saybolt ViscosityD93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D522 Test Methods for Mandrel Bend Test of AttachedOrganic CoatingsD523 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 SurfacesD658 Test Method for Abrasion Resistance of OrganicCoatings by Air Blast Abrasive(Withdrawn 1996)3D659 Method for Evaluating Degree of Chalking of ExteriorPaints(Withdrawn 1990)3D660 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 PanelsD870 Practice for Testing Water Resistance of Coatings1This 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 1931.Last previous edition approved in 2013 as D333 01(2013).DOI:10.1520/D0333-01R21.2For 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 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 Recommendat
