Designation: F2348 − 04 (Reapproved 2017)Standard Performance Specif i cation forPrivacy Padlocks 1This standard is issued under the f i xed 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 specif i cation covers functional, operational, andsecurity requirements for padlocks. Included are functiondescriptions, operational tests, forcing tests, and surreptitiousentry tests.1.2 This specif i cation describes and grades various levels ofperformance to provide users of the specif i cation with criteriaupon which to select suitable padlocks.1.3 Tests described are laboratory tests, and although theysimulate f i eld conditions as to attacks, they do not duplicatethese conditions. Tests described are repeatable in the labora-tory.1.4 Some users of this specif i cation may wish to usepadlocks that have special attributes not related to security.1.5 This specif i cation describes and grades various levels ofperformance provided by limited dual custody operation.1.6 The specif i c 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 Specif i cation 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 specif i cation: 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.
