1、Designation: F 883 04Standard Performance Specification forPadlocks1This standard is issued under the fixed designation F 883; 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 indic
2、ates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers environmental, functional, op-erational, and security
3、requirements for padlocks. Included arefunction descriptions, cycle tests, operational tests, environ-mental tests, forcing tests, and surreptitious entry tests. Noeffort has been made to include criteria for specially madepadlocks used by the Department of Defense or others inhighly sensitive locat
4、ions.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 or the environment, theydo not dup
5、licate these conditions. Tests described are repeat-able in the laboratory.1.4 Some users of this specification may wish to usepadlocks that have special attributes not related to security.These are found in 4.3.1.5 The values stated in SI units are to be regarded as thestandard. The inch-pound unit
6、s given in parentheses areprovided for information only.1.6 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
7、 userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.

Preparation of Apparatus7.1 Tensile Loading DeviceProvide a tensile loading de-vice having a load and force measuring capacity of
28、44 500 N(10 000 lbf).7.2 Shock Impactor:7.2.1 Provide a fixture as illustrated in Fig. 1 which allowsthe weights described in (7.2.2) to be properly guided to strikethe anvil rod which will be placed in direct contact with the topsurface of a padlock using the mounting block described in(7.2.3).7.2.
29、2 Make a set of weights as shown in Fig. 1, with acentral hole in each that allows the weight selected to free falland strike the top surface of the anvil rod.7.2.3 Make a mounting block that will support the specimenon the mounting block when being subjected to the requiredshock load (see Table 1).
30、TEST METHODS8. Forcing Tests (see Table 1)8.1 Tensile Test (Does not apply if test cannot be per-formed) (see 7.1)Support the locked padlock in a fixturebearing against the top surface of the case without interferingwith the shackle or giving support through the top of the caseto the shackle retaini
31、ng mechanism. Apply the required forceslowly along the vertical centerline of the padlock in a directand equal tension on each leg of the shackle. Failure occurs ifthe padlock opens.8.2 Shock TestUsing the impactor (7.2) drop the weightthe required number of times on the top of the locked padlockcas
32、e. Failure occurs if the padlock opens.8.3 Plug Pulling TestDrill the keyway with a No. 20(0.161 in.) diameter drill and insert a Type AB No. 12 screw atleast 19 mm (0.75 in.) deep. Apply the required tension (7.1)axially between the case and the installed screw. Failure occursF883042if the cylinder
33、 plug or cylinder assembly completely separatesfrom the case, or if the padlock can be opened by manipulationwith a screwdriver at the conclusion of the test.NOTE 1Some cylinders are of a configuration such that a differentattachment may be needed in order to apply the required loads.8.4 Plug Torque
34、 Test:8.4.1 Install the padlock in a rigid fixture such as a vise tosupport it firmly but not restrict free rotation of the plug in thecylinder.8.4.2 Insert a blade type tool into the keyway, so that atorque load can be applied to the plug. Failure occurs if thepadlock opens.FIG. 1 (Sheet 1) Shock I
