Designation:D456201(Reapproved 2013)Standard Test Method forShear Strength of Adhesives Using Pin-and-CollarSpecimen1This standard is issued under the fixed designation D4562;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This test method covers the determination of the shearstrength of curing liquid adhesives used for retaining cylindri-cal assemblies or for locking and sealing threaded fasteners.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2A108 Specification for Steel Bar,Carbon and Alloy,Cold-FinishedD907 Terminology of AdhesivesD2651 Guide for Preparation of Metal Surfaces forAdhesiveBondingE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method3.Terminology3.1 DefinitionsMany of the terms in this standard aredefined in Terminology D907.4.Summary of Test Method4.1 This test method consists of bonding a metal pin insidea metal collar and determining the force required to shear theadhesive joint.5.Significance and Use5.1 This test method provides reasonably accurate informa-tion with regard to the ability of an adhesive to withstandshearing forces.It may also be used to determine degree ofcure and the effect of environment on shear strength.6.Apparatus6.1 Universal Test Machine,or equivalent,for applyingforce to the specimen.Details of the test specimen(pin-and-collar)are given in Fig.1.6.2 Specimen Curing Rack,as shown in Fig.2,or equiva-lent.7.Preparation of Test Specimens7.1 Assemble five specimens for each test as described inthe following paragraphs:7.1.1 Each specimen is comprised of a pin 0.498 to 0.499 in.(12.65 to 12.675 mm)in diameter and a slip collar 0.500 to0.501 in.(12.7 to 12.725 mm)inside diameter by 0.435 to0.439 in.(11.05 to 11.15 mm)wide,both components finishedto 32 to 64 in(0.8 to 1.6 m)with 0.001 to 0.003 in.(0.025to 0.075 mm)diametrical clearance between the pin and collar(see Fig.1).The pin and collar,by agreement,may be made ofany material(see Appendix X1),but the most commonmaterial is steel,as specified in Specification A108.7.1.2 Degrease all pins and collars(refer to Guide D2651),store in an atmosphere of low humidity(20%relativehumidity),and keep them clean.Use degreased specimenswithin four days or discard.(Oxidation affects the test resultsafter this time.Prior to vapor degreasing,it is permissible tosoak or wash hard-greased or waxed parts in solvent.)Do notprime or activate unless specified for the material to be tested.7.1.3 To apply the adhesive,assemble the parts to be surethat there are no nicks that will cause them to stick or drag.Disassemble the parts.Apply sufficient adhesive to the circum-ference of the pin,beginning at one end,to completely cover an1This test method is under the jurisdiction of ASTM Committee D14 onAdhesives and is the direct responsibility of Subcommittee D14.60 on AdhesiveMaterial Classification System.Current edition approved July 1,2013.Published July 2013.Originally approvedin 1986.Last previous edition approved in 2007 as D4562 01(2007).DOI:10.1520/D4562-01R13.2For 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 area the width of the collar in its final position.Also applysufficient adhesive to completely cover the interior of the collar360.Slip the collar over the coated end of the pin with at least180 of rotation as the collar travels over the adhesive.Repeata back-and-forth rotation three times,or until the collarexhibits a smooth,consistent resistance to rotation.7.1.4 Rack the assembly with the fillet up so that the collardoes not slip out of the bond area.Take care that the rack is atthe required temperature and do not place onto a hot or coldsurface.There should be excess material on the leading edge ofthe collar;if not,apply sufficient adhesive to create a fillet.7.1.5 Cure the specimens in accordance with the manuf
