1、Designation: F883 13Standard Performance Specification forPadlocks1This standard is issued under the fixed designation F883; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision. A number in parentheses indicat

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,operational, and security requi

3、rements for padlocks. Includedare function descriptions, cycle tests, operational tests, envi-ronmental 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 locations.

4、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 duplicat

5、e 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 giv

6、en 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 user

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

Preparation of Apparatus7.1

30、 Tensile 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 plac

31、ed in direct 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.F883 1327.2.3 Make a mounting block th

32、at will support 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

33、 shall beused to 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.7.3.2.2 A single impact cycle consists of having a bump keyfully inserted into the keyway and withdrawing it one cutFIG. 1 (Sheet

34、1) Shock Impactor (See Table 5 for Bill of Material)F883 133position for the pull 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

35、 or lockoperates after the impact, it failed the test at that cycle and shallbe given 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

36、for locks or cylin-ders as required by the test person if rigid mounting ispreferred.FIG. 2 (Sheet 2) Shock Impactor (See Table 5 for Bill of Material)F883 1347.3.4 The impact device shall be a non-metal instrumentwith a weight not to exceed 0.25 lb.TEST METHODS8.

37、ile Test (Does not apply if test cannot be performed)(see 7.1)Support the locked padlock in a fixture bearingagainst the top surface of the case without interfering with theshackle or giving support through the top of the case to theshackle retaining mechanism. Apply the required force slowlyalong t

38、he vertical centerline of the padlock in a direct and equaltension on each leg of the shackle. Failure occurs if the padlockopens.8.2 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 Pull

39、ing 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 occursif the cylinder plug or cylinder assembly completely separatesfrom the cas

40、e, 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 Test:8.4.1 Install the padlock in a rigid fixture such as

41、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.8.5 Shackle Cutting Test (Does not apply if test cannot beperformed)Shackles shall

42、withstand 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.
