Designation:F234804(Reapproved 2017)Standard Performance Specification forPrivacy Padlocks1This standard is issued under the fixed designation F2348;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 specification covers functional,operational,andsecurity requirements for padlocks.Included are functiondescriptions,operational tests,forcing tests,and surreptitiousentry tests.1.2 This specification describes and grades various levels ofperformance to provide users of the specification with criteriaupon which to select suitable padlocks.1.3 Tests described are laboratory tests,and although theysimulate field conditions as to attacks,they do not duplicatethese conditions.Tests described are repeatable in the labora-tory.1.4 Some users of this specification may wish to usepadlocks that have special attributes not related to security.1.5 This specification describes and grades various levels ofperformance provided by limited dual custody operation.1.6 The specific padlocks included have shackles of limiteddiameter,permitting attachment to existing zipper slides andzipper pulls and other devices provided for closure.1.7 These padlocks are considered“privacy padlocks”of-fering limited protection to forced attack similar to thatprovided by tamper-indicative security seals.A successfulforced attack would be indicated by the damage done to thepadlock.For padlocks offering greater protection to forcedattack,the user is directed to Performance Specification F883.1.8 The values stated in SI units are to be regarded as thestandard.The inch-pound units given in parentheses areprovided for information only.1.9 The following precautionary caveat pertains only to thetest method portions,Sections 8 11,of this specification:Thisstandard does not purport to address the safety concerns,ifany,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:2F883 Performance Specification for Padlocks3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 acceptance testing,vto assure by documented test-ing that a padlock meets specific tests of Specification F2348 asagreed to by the buyer and seller.3.1.2 case,nhousing or body of a lock or latch.3.1.3 certified,vto assure by documented testing that apadlock meets all test requirements appropriate to its grading.3.1.4 combination lock,nlock that is operated by localinput of a specific series or sequence of numbers or letters.3.1.5 cylinder,ncomplete operating unit which usuallyconsists of the plug,shell,tumblers,springs,plug retainer,acam/tailpiece or other actuating device,and all other necessaryoperating parts.3.1.6 cylinder bitting,ngroup of numbers that representthe bitting of a key or the tumblers,or both,of a lock orcylinder.3.1.7 decode,vto determine a key combination by physi-cal measurement of a key or cylinder parts,or both.3.1.8 heel,npart of a padlock shackle that normally isretained in the case when in the unlocked position.3.1.9 independent dual custody,adjfunction of a mecha-nism that allows access by two different people with differentcredentials.3.1.10 keyway,nthe opening in a lock or cylinder that isshaped to accept a key bit or blade of a proper configuration.3.1.11 manipulate,vdialing process typically used withcombination locks to determine operational status of the lock,potential combinations,or attempt to free the mechanism.3.1.12 manipulation,nopening method for mechanicalcombination locks that uses the tolerances of that lock todetermine an opening combination.1This specification is under the jurisdiction of ASTM Committee F12 onSecurity Systems and Equipmentand is the direct responsibility of SubcommitteeF12.50 on Locking Devices.Current edition approved March 1,2017.Published March 2017.Originallyapproved in 2004.Last previous edition approved in 2010 as F2348 04(2010).DOI:10.1520/F2348-04R17.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 3.1.13 padlock,ndetachable and portable lock with ashackle that locks into its
