1.1 This specification covers functional, operational, and security requirements for padlocks. Included are function descriptions, operational tests, forcing tests, and surreptitious entry tests.

1.2 This specification describes and grades various levels of performance to provide users of the specification with criteria upon which to select suitable padlocks.

1.3 Tests described are laboratory tests, and although they simulate field conditions as to attacks, they do not duplicate these conditions. Tests described are repeatable in the laboratory.

1.4 Some users of this specification may wish to use padlocks that have special attributes not related to security.

1.5 This specification describes and grades various levels of performance provided by limited dual custody operation.

1.6 The specific padlocks included have shackles of limited diameter, permitting attachment to existing zipper slides and zipper pulls and other devices provided for closure.

1.7 These padlocks are considered “privacy padlocks” offering limited protection to forced attack similar to that provided by tamper-indicative security seals. A successful forced attack would be indicated by the damage done to the padlock. For padlocks offering greater protection to forced attack, the user is directed to Performance Specification F883.

1.8 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are provided for information only.

1.9 The following precautionary caveat pertains only to the test method portions, Sections 8 - 11, of this specification: This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
