2、es the year of last reapproval. A superscriptepsilon () 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 req
3、uirements 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 location
4、s.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 duplic
5、ate 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 units g

It is the responsibility of the us
7、erof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.

Select on
29、e padlock or cylinder for thecycle test.6.4 Each lock submitted for bump testing shall be suppliedwith seven cut keys that operate the lock.6.5 When appropriate, select one padlock for the salt spraytest (Option E) and three for the environmental tests (OptionG).7. Preparation of Apparatus7.1 Tensil
30、e Loading DeviceProvide a tensile loading de-vice having a load and force measuring capacity of 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 d
31、irect contact with the topsurface of a padlock using the mounting block described in(7.2.3).7.2.2 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
32、 the specimenon the mounting block when being subjected to the requiredshock load (see Table 1).7.3 Key Bumping:7.3.1 Each locksmith performing the test shall use two ofthe supplied keys to fabricate his own pull bump key and pushbump key.7.3.2 Both a pull bump key and a push bump key shall beused t
33、o test a lock or cylinder for bump resistance by each ofthree locksmiths.7.3.2.1 Atorque bar is permitted to be used if the test personprefers that method.F883 0927.3.2.2 A single impact cycle consists of having a bump keyfully inserted into the keyway and withdrawing it one cutposition for the pull
34、 type, inserting the key fully into thekeyway and then releasing it to allow the pins to center it forthe push type, impacting the end of the key to drive it fully intothe keyway while torque is applied. If the cylinder or lockoperates after the impact, it failed the test at that cycle and shallbe g
35、iven the appropriate grade level for the last cycle that didnot accomplish operation. If it did not operate, a new cycleshall be achieved until the lock or cylinder reaches Grade 6.7.3.3 Provide various mounting blocks for locks or cylin-ders as required by the test person if rigid mounting isprefer

Forcing Tests (see Table 1)8.1 Tensile Test (Does not apply if test cannot be per-formed) (see 7.1)Support the locke
37、d 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 retaining mechanism. Apply the required forceslowly along the vertical centerline of the padlock in a directand equal tension on each leg
38、of the shackle. Failure occurs ifthe padlock opens.FIG. 2 (Sheet 2) Shock Impactor (See Table 5 for Bill of Material)F883 0948.2 Shock TestUsing the impactor (7.2) drop the weightthe required number of times on the top of the locked padlockcase. Failure occurs if the padlock opens.8.3 Plug Pulling T
39、estDrill 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 occursif the cylinder plug or cylinder assembly completely separatesfrom the case, or
40、 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 Test:8.4.1 Install the padlock in a rigid fixture such as a vis
41、e 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.8.5 Shackle Cutting Test (Does not apply if test cannot beperformed)Shackles shall withs
42、tand cutting through when 2shearing blades made of a steel hardened to a minimumhardness of Rc 50, are used in conjunction with the bladepositioning holder, is placed in a tensile loading device (7.1)having a compression load capability and compressed with therequired force. See Fig. 4 for details.
43、Failure occurs if theshackle is cut through. Padlocks specified with Option F arenot subject to 8.6.9. Surreptitious Entry Tests (see Table 2)9.1 Picking or Manipulating Test:9.1.1 Cylinders in padlocks shall resist picking (see 5.1) forthe required time. Combination padlocks shall resist manualmani

Cylinders inpadlocks containing o
45、ther tumbler elements shall be loadedusing maximum ranges. If lock design and cylinders used arethe same in several different sizes of padlocks submitted fortesting, only a total of five samples of any size or sizes need tobe tested.9.1.3 The tools used for this test shall be manual manipu-lating to
46、ols required by the operator, providing no visiblemarks are left detectable by the unaided eye.9.2 Cylinder Impressioning and Decoding Tests:9.2.1 Cylinders shall resist successful impressioning anddecoding (see 5.1) for the required time.FIG. 3 (Sheet 3) Shock Impactor (See Table 5 for Bill of Mate
