Designation:B90500(Reapproved 2016)Standard Test Methods forAssessing the Adhesion of Metallic and Inorganic Coatingsby the Mechanized Tape Test1This standard is issued under the fixed designation B905;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 describe procedures for assessingthe adhesion of metallic and inorganic coatings and other thinfilms to metallic and nonmetallic substrates.Assessment ismade by applying pressure-sensitive tape to a coated surfaceand then utilizing a mechanical device to remove the tape at aregulated,uniform rate and constant angle while simultane-ously recording the removal force.1.2 Four methods are described.Methods A1 and A2 areintended primarily for use on parts.Methods B1 and B2 areintended primarily for use in laboratory evaluations.MethodsB1 and B2 are not recommended for testing coatings and filmson polymer substrates.1.3 These test methods may be used to establish whether theadhesion of a coating to a substrate is within a required range(between a quantified low and a quantified high level).Deter-mination of actual adhesive forces requires more sophisticatedmethods of measurement.In multilayer systems adhesionfailure may occur between intermediate coating layers so thatthe adhesion of the total coating system to the substrate maynot necessarily be determined.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 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.2.Referenced Documents2.1 ASTM Standards:2B183 Practice for Preparation of Low-Carbon Steel forElectroplatingB242 Guide for Preparation of High-Carbon Steel for Elec-troplatingB252 Guide for Preparation of Zinc Alloy Die Castings forElectroplating and Conversion CoatingsB253 Guide for Preparation of Aluminum Alloys for Elec-troplatingB254 Practice for Preparation of and Electroplating onStainless SteelB281 Practice for Preparation of Copper and Copper-BaseAlloys for Electroplating and Conversion CoatingsB320 Practice for Preparation of Iron Castings for Electro-platingB343 Practice for Preparation of Nickel for Electroplatingwith NickelB480 Guide for Preparation of Magnesium and MagnesiumAlloys for ElectroplatingB481 Practice for Preparation of Titanium and TitaniumAlloys for ElectroplatingB482 Practice for Preparation of Tungsten and TungstenAlloys for ElectroplatingB537 Practice for Rating of Electroplated Panels Subjectedto Atmospheric ExposureB538 Method of FACT(Ford Anodized Aluminum Corro-sion Test)(Withdrawn 1986)3B629 Practice for Preparation of Molybdenum and Molyb-denum Alloys for ElectroplatingB630 Practice for Preparation of Chromium for Electroplat-ing with ChromiumB727 Practice for Preparation of Plastics Materials for Elec-troplatingD1730 PracticesforPreparationof AluminumandAluminum-Alloy Surfaces for Painting1These test methods are under the jurisdiction of ASTM Committee B08 onMetallic and Inorganic Coatings and are the direct responsibility of SubcommitteeB08.10 onTest Methods.Current edition approved Nov.1,2016.Published November 2016.Originallyapproved in 2000.Last previous edition approved in 2010 as B905 00(2010).DOI:10.1520/B0905-00R16.2For 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 States1 D1731 Practices for Preparation of Hot-Dip Aluminum Sur-faces for PaintingD1732 Practices for Preparation of Magnesium Alloy Sur-faces for PaintingD2370 Test Method for Tensile Properties of Organic Coat-ingsD3330/D3330M Test Method for PeelAdhesion of Pressure-Sensitive TapeD3359 Test Methods for Measuring Adhesion by Tape Test3.Summary of Test Method3.1 Pressure-sensitive tape is adhered to the surface of thecoating and then removed utilizing a motorized mechanicaldevice that peels the tape at a constantly maintained angle andcontrolled rate of peel.Adigital recording force gage is used torecord the maximum peel force.NOTE1All due care must be taken to ensure that test specimens arehandled and stored such that they are not subjected to conditions that willcause deleterious effects.These conditions include but are not limited tohandling without the use of gloves,storing in
