Designation:D3359092Standard Test Methods forMeasuring Adhesion by Tape Test1This standard is issued under the fixed designation D3359;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.1NOTEFootnote 5 and 5.2 were corrected editorially in June 2010.2NOTEFootnote 5 and 5.2 were corrected editorially and moved into Note 4 in 5.3 in July 2010.1.Scope*1.1 These test methods cover procedures for assessing theadhesion of coating films to metallic substrates by applying andremoving pressure-sensitive tape over cuts made in the film.NOTE1This test method has been reported being used to measureadhesion of organic coatings on soft substrates(for example,wood andplastic).Issues with plastic substrates are noted in Appendix X1.Asimilartest method,ISO 2409,permits tests on soft substrates(for example,woodand plaster).Precision and bias data on the later is lacking.Test MethodsD3359 was developed with metal as the substrate and,in the absence ofsupporting precision and bias data,is so limited.1.2 Test Method A is primarily intended for use at job siteswhile Test Method B is more suitable for use in the laboratory.Also,Test Method B is not considered suitable for films thickerthan 5 mils(125m).NOTE2Subject to agreement between the purchaser and the seller,Test Method B can be used for thicker films if wider spaced cuts areemployed.1.3 These test methods are used to establish whether theadhesion of a coating to a substrate is at a generally adequatelevel.They do not distinguish between higher levels ofadhesion for which more sophisticated methods of measure-ment are required.NOTE3It should be recognized that differences in adherability of thecoating surface can affect the results obtained with coatings having thesame inherent adhesion.1.4 This test method is similar in content(but not techni-cally equivalent)to ISO 2409.1.5 In multicoat systems adhesion failure may occur be-tween coats so that the adhesion of the coating system to thesubstrate is not determined.1.6 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.7 This standard does not purport to address the safetyconcerns,if any,associated with its use.It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D609 Practice for Preparation of Cold-Rolled Steel Panelsfor Testing Paint,Varnish,Conversion Coatings,andRelated Coating ProductsD823 Practices for Producing Films of Uniform Thicknessof Paint,Varnish,and Related Products on Test PanelsD1000 Test Methods for Pressure-Sensitive Adhesive-Coated Tapes Used for Electrical and Electronic Applica-tionsD1730 PracticesforPreparationof AluminumandAluminum-Alloy Surfaces for PaintingD2092 Guide for Preparation of Zinc-Coated(Galvanized)Steel Surfaces for Painting(Withdrawn 2008)3D2370 Test Method for Tensile Properties of Organic Coat-ingsD3330/D3330M Test Method for PeelAdhesion of Pressure-Sensitive TapeD3924 Specification for Environment for Conditioning andTesting Paint,Varnish,Lacquer,and Related MaterialsD4060 Test Method for Abrasion Resistance of OrganicCoatings by the Taber Abraser1These test methods are under the jurisdiction of ASTM Committee D01 onPaint and Related Coatings,Materials,and Applications and are the directresponsibility of Subcommittee D01.23 on Physical Properties of Applied PaintFilms.Current edition approved June 1,2009.Published June 2009.Originallyapproved in 1974.Last previous edition approved in 2008 as D3359 08.DOI:10.1520/D3359-09E02.2For 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.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.2 Other Standard:ISO 2409 Paint and Varnishes Cross-cut test43.Summary of Test Methods3.1 Test Method AAn X-cut is made through the film tothe substrate,pressure-sensitive tape is applied over the cut andthen removed,and adhesion is assessed qualitatively on the 0to 5 scale.3.2 Test Method BA lattice pattern with either six oreleven cuts in each direction is made in the film to thesubstrate,pressure-sensitive tape is applied over the lattice andthen removed,and adhesion is evaluated by comparison withdescriptions and illustrations.4.Significance and Use4.1 If a coating is to fulfill its function of protecting
