Designation:F115704(Reapproved 2015)Standard Practice forClassifying the Relative Performance of the PhysicalProperties of Security Seals1This standard is issued under the fixed designation F1157;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 practice covers methods for testing the physicalproperties of mechanical(passive)security seals.Whereappropriate,the various tests include particular apparatus orprocedural specifications required for different types of secu-rity seals.This practice does not address adhesive(tape or labelstyle)or electronic types of security seals.1.2 This practice will serve as a basis for comparing theresponse of various security seals under different simulatedmodes of attack.The security seal to be evaluated shall first beclassified into established groupings,and then tested in themanner designated as most suitable for that class of seal,inaccordance with Classification F832.1.3 A mechanical security seal is a single use,passivedevice intended to detect tampering or entry into the sealeditem.Removal of the security seal requires permanent andirreversible damage to the seal.The following proceduresreflect the relative performance of security seals when subjectto various destructive physical attacks.These tests simulateknown and likely security seal implementation and attackmethods.1.4 Security seals often contain unique identification mark-ings for authentication purposes to discourage duplication andto prevent reapplication.This practice does not address uniqueidentifiers or vulnerabilities of security seals.NOTE1See Guide F1158 for procedures on the inspection andevaluation of tampering of security seals.See also Guide F946.1.5 It is the responsibility of users of this practice tointerpret their specific security needs concerning the applica-tion of seals,and to determine the grade of seal appropriate fortheir particular application.ASTM assumes no responsibilityfor losses occurring as a result of a defeated seal,whether thedefeat is apparent,or the seal is not suited for its application.1.6 The values as stated in inch-pound units are to beregarded as the standard.The values in parentheses are givenfor information only.1.7 The following safety hazards caveat pertains only to thetest procedures portion,Section 6,of this practice.Thisstandard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.Referenced Documents2.1 ASTM Standards:2F832 Classification for Security SealsF883 Performance Specification for PadlocksF946 Guide for Establishing Security Seal Control andAccountability ProceduresF1158 Guide for Inspection and Evaluation of Tampering ofSecurity Seals3.Terminology3.1 Definitions:3.1.1 lockedsealcondition,asintendedbythemanufacturer,which secures the sealed item and cannot bereversed or opened without physical destruction of the securityseal.3.1.2 open conditioncondition which could allow entryinto the sealed item and,for the purposes of this practice,afailed security seal.3.1.3 security sealpassive,one-time locking device usedto indicate tampering or entry,and may be designed to offer1This practice is under the jurisdiction of ASTM Committee F12 on SecuritySystems and Equipment and is the direct responsibility of Subcommittee F12.50 onLocking Devices.Current edition approved Jan.1,2015.Published January 2015.Originallyapproved in 1988.Last previous edition approved in 2010 as F1157 04(2010).DOI:10.1520/F1157-04R15.2For 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 limited resistance to forced entry.Security seals require inspec-tion to determine a tampering or entry event.4.Summary of Practice4.1 A security seal shall be evaluated in accordance with itsclassification into one of five general groups and its perfor-mance in the following six tests:pull(tensile)shear,bending,impact,low temperature impact,and high temperature pull(tensile).4.2 A security seal shall receive a grade designation basedupon its measured performance in each of the required tests.This grade shall be obtained by testing five individual seals ineach of the six specific tests.A minimum of 30 security sealspecimens shall be required to complete testing.The gradedesignation shall be determined by comparing the averagevalue of the five test results to the
