Standard Test Method for Vehicle Crash Testing of ...

1 Designation: F 2656 07 Standard Test Method forVehicle Crash Testing of perimeter barriers1 This Standard is issued under the fixed designation F 2656; 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 indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or perimeter barrier test methods were first published in 1985 by the Bureau of DiplomaticSecurity to assess the Crash performance of perimeter barriers and gates. Since that time, the frequencyand scale of attacks using vehicles with or without an explosive payload have increased bothinternationally and domestically. Therefore, there is a need to address a broad spectrum of possibleincident conditions such as credible threat Vehicle types for the locale, attack velocities of the differentvehicles, and different acceptable penetration limitations.

2 Also, there are different evaluation criteriafor different agencies that fulfill their unique access control operations, aesthetics, and otherorganizational requirements. This test Method is intended to expand the current Department of State,Bureau of Diplomatic Security s Crash Testing Standard to meet the broader needs of multipleorganizations responsible for the protection of assets domestically and test standards for perimeter security devices have previously been maintained by the Department, Bureau of Diplomatic Security. The Specification for Vehicle Crash Test ofPerimeter Barriers and Gates was first published in 1985 In that Standard , the testvehicle was specified as a medium-duty truck weighing 6800 kg (15 000 lb). The payload was to besecurely attached to the frame and nominal impact velocities were 50 km/h (30 mph), 65 km/h (40mph), and 80 km/h (50 mph).

3 Penetration limits were1m(3ft), 6 m (20 ft), and 15 m (50 ft) and weremeasured from the attack face of the perimeter security device to the final resting position of the frontof the frame rails of the test 2003, the State Department, Bureau of Diplomatic Security issued an updated Standard ( , Revision A) for the Testing of perimeter barriers. This update was done for severalreasons. The foremost reason for change was limited setback distances precluded the use of anydevices at their facilities or compounds that did not meet the highest test level, that is, those allowingmore than 1-m (3-ft) penetration distance. Therefore, the revised Standard only uses a 1-m (3-ft)penetration distance. Secondly, the Method of rigid attachment of the ballast to the test Vehicle was notsimulating likely payload configurations and was altering the structural integrity of the test , the updated Standard requires a payload consisting of 208-L (55-gal) steel drumsstrapped together that have been filled with soil.

4 This assembly is then strapped to the Vehicle loadplatform. The third reason for change was based on the observation that the cargo bed of trucks couldeffectively penetrate certain types of barriers. Accordingly, the penetration distance is now measuredfrom the inside face or non-impact surface of the barrier to the front of the cargo bed when the vehiclehas reached its final position. Lastly, it was determined that the trucks used different platforms withina given class affecting result consistency. The revised test Standard now requires the use of veryspecific diesel-powered medium-duty This test Method provides a range of Vehicle impactconditions, designations, and penetration performance will allow an agency to select passive perimeter barriersand active entry point barriers appropriate for use at facilitieswith a defined moving Vehicle threat.

5 Agencies may adopt andspecify those condition designations and performance levels inthis test Method that satisfy their specific needs. Agencies mayalso assign certification ratings for active and passive perimeterbarriers based on the tests and test methodologies describedherein. Many test parameters are standardized to arrive at a1 This test Method is under the jurisdiction of ASTM Committee F12 on SecuritySystems and Equipment and is the direct responsibility of Subcommittee onSystems Products and edition approved Aug. 1, 2007.

6 Caution should beexercised in interpreting test findings and in extrapolatingresults to other than test conditions. While computer simula-tions are powerful tools that are useful in the development ofnew and improved barriers or in estimating performance underdiffering conditions, use of only the results from computersimulation for fielding a product is strongly discouraged. Whenperforming a test, developers and users are encouraged toaddress specific or unusual site conditions as needed. Oftenlocal terrain features, soil conditions, climate, or other itemswill dictate special needs at specific locations. Therefore, if siteconditions are likely to degrade a barrier s performance, theagency in need of a perimeter barrier should require testingwith the specific site conditions replicated for full-scale Product/design certification under this test Method onlyaddresses the ability of the barrier to withstand the impact ofthe test Vehicle .
