SD-STD-02.01, Revision A, March 2003

Test Method for Vehicle Crash Testing Of Perimeter Barriers and Gates

This standard is issued by the U.S. Department of State, Bureau of Diplomatic Security, Office of Physical Security Programs, Physical Security Division, SA-14, Washington, D.C. 20520-1403. Copies of this Standard may be obtained from this office. Revision A replaces SD-STD-02.01, April 1985, in its entirety.

Only the Bureau of Diplomatic Security may determine and assign certification ratings for anti-ram barriers. 
The test method provides specified levels of vehicle impact resistance required by the U.S. Department of State (DOS) Bureau of Diplomatic Security (SD) to select appropriate perimeter barriers and gates for use at high security facilities. Many test parameters are standardised to arrive at a single vehicle type and mass, enhance test realism and replication, and produce consistent rating designations.

Compliance with these rating designations establishes a measure of performance, but does not render any perimeter barrier or gate invulnerable to vehicle penetration. Caution should be exercised in interpreting test findings and projecting results to other hypothetical conditions. Developers and users agencies are encouraged to continue beyond these test conditions and address specific or unusual site conditions as needed.

Product/design certification under this Standard 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.

K4 = Vehicle travelling at 50kph (30mph) on impact

K8 = Vehicle travelling at 65kph (40mph) on impact

K12 = Vehicle travelling at 80kph (50mph) on impact
