Standard Test Method for Vehicle Crash Testing of Perimeter Barriers
SIGNIFICANCE AND USE
This test method provides a structured procedure to establish a penetration rating for perimeter barriers subjected to a vehicle impact. Knowing the penetration rating provides the ability to select an appropriate barrier for site-specific conditions around a facility.
The barrier penetration rating does not imply that a barrier will perform as rated in all site conditions, approach routes, and topography. Also, only single-specimen tests at a specified impact location are required by this test method, and therefore, not all points of impact can be tested and validated for the penetration rating. Other impact locations may respond differently.
SCOPE
1.1 This test method provides a range of vehicle impact conditions, designations, and penetration performance levels. This will allow an agency to select passive perimeter barriers and active entry point barriers appropriate for use at facilities with a defined moving vehicle threat. Agencies may adopt and specify those condition designations and performance levels in this test method that satisfy their specific needs. Agencies may also assign certification ratings for active and passive perimeter barriers based on the tests and test methodologies described herein. Many test parameters are standardized to arrive at a common vehicle type and mass, enhance test realism and replication, and produce uniform rating designations.
1.2 Compliance with these test procedures establishes a measure of performance but does not render any perimeter barrier invulnerable to vehicle penetration. Caution should be exercised in interpreting test findings and in extrapolating results to other than test conditions. While computer simulations are powerful tools that are useful in the development of new and improved barriers or in estimating performance under differing conditions, use of only the results from computer simulation for fielding a product is strongly discouraged. When performing a test, developers and users are encouraged to address specific or unusual site conditions as needed. Often local terrain features, soil conditions, climate, or other items will dictate special needs at specific locations. Therefore, if site conditions are likely to degrade a barriers performance, the agency in need of a perimeter barrier should require testing with the specific site conditions replicated for full-scale crash testing.
1.3 Product/design certification under this test method only addresses the ability of the barrier to withstand the impact of the test vehicle. It does not represent an endorsement of the product/design or address its operational suitability.
1.4 The values in SI units are to be regarded as the standard. The values shown in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

INTRODUCTION
Original perimeter barrier test methods were first published in 1985 by the Bureau of Diplomatic
Securitytoassessthecrashperformanceofperimeterbarriersandgates.Sincethattime,thefrequency
and scale of attacks using vehicles with or without an explosive payload have increased both
internationally and domestically. Therefore, there is a need to address a broad spectrum of possible
incident conditions such as credible threat vehicletypesfor thelocale, attackvelocitiesofthedifferent
vehicles, and different acceptable penetration limitations. Also, there are different evaluation criteria
for different agencies that fulfill their unique access control operations, aesthetics, and other
organizational 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 multiple
organizations responsible for the protection of U.S. assets domestically and abroad.
PublishedteststandardsforperimetersecuritydeviceshavepreviouslybeenmaintainedbytheU.S.
State Department, Bureau of Diplomatic Security. The Specification for Vehicle Crash Test of
Perimeter Barriers and Gates was first published in 1985 as SD-STD-02.01. In that standard, the test
vehicle was specified as a medium-duty truck weighing 6800 kg (15 000 lb). The payload was to be
securely attached to the frame and nominal impact velocities were 50 km/h (30 mph), 65 km/h (40
mph), and 80 km/h (50 mph). Penetrationlimitswere1m(3 ft), 6m(20ft), and15m(50ft) andwere
measured from the attack face of the perimeter security device to the final resting position of the front
of the frame rails of the test vehicle.
In 2003, the U.S. State Department, Bureau of Diplomatic Security issued an updated standard
(SD-STD-02.01, Revision A) for the testing of perimeter barriers. This update was done for several
reasons. The foremost reason for change was limited setback distances precluded the use of any
devices at their facilities or compounds that did not meet the highest test level, that is, those allowing
more than 1-m (3-ft) penetration distance. Therefore, the revised standard only uses a 1-m (3-ft)
penetrationdistance.Secondly,themethodofrigidattachmentoftheballasttothetestvehiclewasnot
simulating likely payload configurations and was altering the structural integrity of the test vehicle.
Consequently, the updated standard requires a payload consisting of 208-L (55-gal) steel drums
strapped together that have been filled with soil. This assembly is then strapped to the vehicle load
platform. The third reason for change was based on the observation that the cargo bed of trucks could
effectively penetrate certain types of barriers. Accordingly, the penetration distance is now measured
from the inside face or non-impact surface of the barrier to the front of the cargo bed when the vehicle
has reached its final position. Lastly, it was determined that the trucks used different platforms within
a given class affecting result consistency. The revised test standard now requires the use of very
specific diesel-powered medium-duty trucks.
