Designation:D373010Standard Guide forTesting High-Performance Interior Architectural WallCoatings1This standard is issued under the fixed designation D3730;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 test methodsfor high-performance interior architectural wall coatings(HIPAC)that differ from more conventional coatings by beingtougher,more stain-resistant,more abrasion-resistant and,ordinarily,designed to be applied to wall surfaces of steel,masonry(poured concrete,concrete block,or cinder block),and plaster or gypsum wallboard.The tests that are listed inTable 1 and Table 2 are designed to measure performanceproperties.These tests may not all be required for each HIPACsystem.Selection of the test methods to be followed must begoverned by experience and the requirements in each indi-vidual case,together with agreement between the purchaserand the seller.1.2 High-performance architectural coatings are tough,extra-durable organic coating systems that are applied as acontinuous(seamless)film and cure to a hard finish.The finishcan be high gloss,semigloss,or low gloss as desired.Thesecoatings are resistant to persistent heat,humidity,abrasion,staining,chemicals,and fungus growth.They are used in areaswhere humidity,wear,or unusual chemical resistance require-ments,particularly to soiling,are required and where strongdetergents are used to maintain sanitary conditions.Halls andstairways in public buildings,lavatories,stall showers,lockerareas,animal pens,and biological laboratories are typicalapplications.In addition,food processing plants,dairies,res-taurants,schools,and transport terminals frequently useHIPAC systems.These are effective in many areas of buildinginteriors compared with tile and are of low materials andmaintenance costs.They are used as a complete system only asrecommended by the manufacturer since the individual coats ina system are formulated to be compatible with each other.HIPAC systems should be applied only to properly preparedsurfaces such as steel or masonry,including cinder blocks andcement blocks.They can be applied over plaster and gypsumwallboard.Ordinarily,a prime or fill coat,if required,is part ofthe system.1.3 While they are excellent for walls,HIPAC are notusually intended for ceilings and floors.They would notordinarily be used in homes,although parents with smallchildren might want to use HIPAC coatings on some walls.1.4 The types of resin ordinarily used are the following:epoxy-polyamide,two-package;polyester-epoxy,two-package;polyurethane,one-package or two-package.How-ever,other resin types are not excluded provided they can meetthe requirements(performance specifications)laid down by thepurchaser.1.5 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.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 and health practices and determine the applica-bility of regulatory limitations prior to use.For a specifichazard statement,see the note in 7.6.2.Referenced Documents2.1 ASTM Standards:2D16 Terminology for Paint,Related Coatings,Materials,andApplicationsD93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD154 Guide for Testing VarnishesD185 Test Methods for Coarse Particles in PigmentsD344 Test Method for Relative Hiding Power of Paints bythe Visual Evaluation of BrushoutsD523 Test Method for Specular GlossD562 Test Method for Consistency of Paints MeasuringKrebs Unit(KU)Viscosity Using a Stormer-Type Viscom-eter1This 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 Dec.1,2010.Published February 2011.Originallyapproved in 1978.Last previous edition approved in 2003 as D3730 03.DOI:10.1520/D3730-10.2For 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 States1 D869 Test Method for Evaluating Degree of Settling of PaintD1005 Test Method for Measurement of Dry-Film Thick-ness of Organic Coatings Using MicrometersD1186 Test Methods for Nondestructive Measurement ofDry Film Thickness of Nonmagnetic Coatings Applied toa Ferrous Base(Withdrawn 2006)3D1210 Test Method for Fineness of Dispersion of Pigment-Vehicle Systems by Hegman-
