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 These test methods cover door assemblies of var
3、iousmaterials and types of construction for use in wall openings todeter unwanted intruders.1.2 Door assemblies, covered by these test methods, alsoinclude individual components such as the hinge, lock, door,jamb/strike, and jamb/wall.1.3 These test methods are designed to measure the capa-bility of
4、 a swinging door assembly to restrain or delay and tofrustrate the commission of “break-in” crimes.1.4 These test methods apply primarily to typical entry doorassemblies in single- and multi-family residential housing.1.5 This standard does not purport to address all of thesafety concerns, if any, a

Significance and Use4.1 Crime statistics show
20、that the majority of all burglaryattacks are on residential property. These test methods are,therefore, designed to aid in identifying a level of physicalrestraint, by swinging door assemblies, that will help reducethis large increment of crime.4.2 These test methods are not intended to provide amea
21、sure of resistance for a door assembly subjected to attacksby skilled burglars on high pay-off targets. These attacks andtargets require higher level, more sophisticated resistance,which usually includes alarms, communication, and apprehen-sion systems.4.3 The wall assembly described in 7.3 is consi
22、deredsuitable for the scope of these test methods. Wall constructionthat differs in dynamic response from that described in 6.3 mayrequire testing in accordance with Section 11.4.4 The primary purpose of this standard is to providedetailed test methods. Acceptance criteria for performancelevels are
23、considered a matter for authorities having jurisdic-tion. Some potential guidelines may be found in Annex A1.5.

44、bolt load, install them in thetest fixture described in 6.5.9. Procedure9.1 One complete assembly shall be used to conduct thetests. Tests shall be given in the sequence of Sections 10-21.Tests under Sections 10, 12, 13, 14, 15, and 16, if conducted inthe test panel shall not be repeated in the door
45、 assembly beingtested. These tests need not be repeated for successive tests ofother door assemblies where the same lock model is beingused.NOTE 1Vertical members are equivalent to, or better in bending than, W8 3 10 steel beam.NOTE 2Horizontal members are equivalent to, or better in bending than,a2
46、by8-ft wood plank.NOTE 3Diagonal members are equivalent to, or better than, 2 by 2 by14 in.-steel angle.NOTE 4Adequate floor anchorage of the entire wall support fixture is essential.FIG. 1 Wall Support FixtureF 476 84 (2002)310. Static Bolt Load Test10.1 To test Type A and B locks and all door asse
47、mblylocks, mount the lock in the test fixture described in 6.5. Lockthe door lock with the dead bolt or dead latch in the fullyprojected position. If the lock incorporates a dead-latchplunger, attach a 6.5-mm (14-in.) spacer to the lock front.Allow the dead-latch plunger to project flush with the to
48、p of thespacer, and hold it in that position with a piece of tape, or byanother suitable means.10.2 Place the lock, in the test fixture, in a compressiontesting machine, or mount it on a firm, level surface with thecompression loading device directly above it with the loadingface parallel to the loc
49、k front, and the axis of the hydraulic ramperpendicular to the lock front. Apply an increasing compres-sive load to the end of the latch bolt or the dead bolt. Note themaximum force required to depress the latch bolt or the deadbolt to where the farthest point on the bolt is 6 mm (14 in.) fromthe lock front surface.10.3 To test for bolt projection, apply end pressure to theprojected dead bolt or dead latch and measure the distancefrom the lock front surface to the farthest point on the bolt orlatch at the center line.10.3.
