Designation:D373017Standard 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 resistancerequirements,particularly to soiling,are required and wherestrong detergents are used to maintain sanitary conditions.Halls and stairways in public buildings,lavatories,stallshowers,locker areas,animal pens,and biological laboratoriesare typical applications.In addition,food processing plants,dairies,restaurants,schools,and transport terminals frequentlyuse HIPAC systems.These are effective in many areas ofbuilding interiors compared with tile and are of low materialsand maintenance costs.They are used as a complete systemonly as recommended by the manufacturer since the individualcoats in a system are formulated to be compatible with eachother.HIPAC systems should be applied only to properlyprepared surfaces such as steel or masonry,including cinderblocks and cement blocks.They can be applied over plaster andgypsum wallboard.Ordinarily,a prime or fill coat,if required,is part of the 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-packageortwo-package.However,other resin types are not excluded provided they canmeet the requirements(performance specifications)laid downby the purchaser.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 7.6.1.7 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:2D16 Terminology for Paint,Related Coatings,Materials,andApplicationsD93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD154 Guide for Testing Varnishes1This 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 June 1,2017.Published June 2017.Originallyapproved in 1978.Last previous edition approved in 2010 as D3730 10.DOI:10.1520/D3730-17.2For 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 D185 Test Methods for Coars
