Designation:B56504(Reapproved 2015)Standard Test Method forShear Testing of Aluminum and Aluminum-Alloy Rivets andCold-Heading Wire and Rods1This standard is issued under the fixed designation B565;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 double shear testing ofaluminum and aluminum alloy rivets with round,solid shanksand cold-heading wire and rod.2NOTE1Exceptions to this test method may be necessary in individualspecifications or methods for tests for a particular material.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 The latest issues of the following documents form a partof this standard to the extent referenced herein:2.2 ASTM Standards:3B316/B316M Specification for Aluminum and Aluminum-Alloy Rivet and Cold-Heading Wire and RodsB769 Test Method for Shear Testing of Aluminum AlloysB831 Test Method for Shear Testing of Thin AluminumAlloy ProductsE4 Practices for Force Verification of Testing MachinesE6 Terminology Relating to Methods of Mechanical Testing3.Terminology3.1 GeneralThe definitions of terms relating to sheartesting in Terminology E6 are applicable to the terms used inthis test method.4.Summary of Test Method4.1 The test consists of subjecting a length of wire or rod ora rivet in full cross section,or a machined length of rod or rivet,to double-shear loading,with a suitable test device in a tensiontesting machine,and determining the shear stress required tofracture the specimen(that is,the shear strength).5.Significance and Use5.1 This test method is intended solely for the shear testingof rivets and cold-heading wire and rod,and is not generallyrecommended for the determination of the shear strength ofother products.For rivets,this method is limited to rivetshaving a shank length equal to or greater than 2d.NOTE2The results of shear tests of specimens machined fromproducts other than wire,rod,and rivets may be greatly dependent uponthe orientation of the specimen within the original test material,and thedirection in which the force is applied relative to the grain flow in thespecimen.4It is recommended that shear strengths of other products bedetermined by Test Method B769 for products greater than 0.250 in.(6.4mm)and Test Method B831 for products less than 0.250 in.(6.4 mm).Shear strengths developed by this test method have been shown to varyfrom those developed by other methods.4If Test Method B565 is used forshear testing of other products,variables such as those described in TestMethod B769 should be identified and controlled.5.2 The results of shear tests are dependent upon the relativeand absolute lengths of specimen which are sheared out,andthose which are supported.4The results of tests made inaccordance with this method should not be directly comparedwith those determined in other types of tests in which themethods of loading and supporting the specimen are different.5.3 The presence of a lubricant on the surfaces of thespecimen and device may result in shear strengths up to 3%lower than those determined in the absence of lubrication.1This test method is under the jurisdiction of ASTM Committee B07 on LightMetals and Alloysand is under the jurisdiction of Subcommittee B07.05 on Testing.Current edition approved Oct.1,2015.Published October 2015.Originallyapproved in 1972.Last previous edition approved in 2010 as B565 04(2010).DOI:10.1520/B0565-04R15.2This product is covered by Specification B316/B316M.3For 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.4Kaufman,J.G.,and Davies,R.E.“Effects of Test Method and SpecimenOrientation on Shear Strengths of Aluminum Alloys,”ASTM Proceedings,ASTEA,Am.Soc.Testing Mats.,Vol 64,1964.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 NOTE3In order to be able to test rivets having shanks as short as 2d,the supported lengths of the specimen are12d(Fig.1),although it isrecognized that higher values of shear strength would be obtained if thesupporting lengths were longer.5.4 Inve
