1、Designation: F 2781 09Standard Practice forTesting Forced Entry Resistance of Security FenceSystems1This standard is issued under the fixed designation F 2781; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revisi

Scope1.1 The forced entry resistance of fence systems is evalu-ated relative to three levels of forced entry threat using thelimited hand

3、tool inventory outlined in Table 1. It alsoestablishes a system for rating the forced entry resistance ofthose systems (see Table 2). The tools specified to be used fortesting at each threat level are those that are known to have amaximum destructive effect on structures and their sub-assemblies and

Summary of Practice3.1 For each rating a structured portion and a discretionaryportion as described in

8、3.2 and 3.3 is required.3.2 The structured portion of the test provides for a zero tofive minute test with specific tools selected as the mostdebilitating from the tool list in Table 1, regardless of the fencesystem being tested.3.3 Following the structured portion of the test, the discre-tionary po

9、rtion of the test provides up to 55 minutes of testing,optimizing forced entry efforts by selecting any (or all) toolsfrom the applicable category of the list (low (A), medium (B),or aggressive (C). Selection of tools is based on the perceptionof the test director as to which tools will most effecti

It is important to recognize that thelowest threat level time will establish the maximum time

12、limitfor a greater threat level.4. Significance and Use4.1 The success or failure of any attempt to forcefullypenetrate a fence system is dependent upon three primaryfactors that collectively define the threatthe tools and devicesemployed, the number of aggressors, and their level of sophis-tication

However, rapidly changingsocial conditions have created an immediate need for buildingcomp
