1、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 i
2、n 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
3、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
4、 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 cust

6、vided 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.
7、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 responsi
