Department of State (DOS) Crash Test Certification

Prior to Department of State (DOS) certification, vehicle barriers must be tested by an independent crash test facility to meet DOS standards.

  • Speed (K)
  • Penetration

The test specifies perpendicular barrier impact by a 15,000 lb. (6810 kg.) vehicle.

Certification Class Speed in mph Speed in kph
K12 50 mph 80 kph
K8 40 mph 65 kph
K4 30 mph 48 kph

To become certified with a Department of State "K" rating the 15,000 vehicle must achieve one of the K rating speeds (50 mph, 40 mph, or 30 mph) and the bed of the truck must not penetrate the barrier by more than 36 inches.

The DOS has awarded contracts subject to this qualification or earlier versions of this qualification requirement since fiscal year 2000.

When a product is submitted for department of State qualification testing, the product manufacturer must provide any information that may be requested of the manufacturer before testing will begin. The manufacturer must arrange, schedule, and pay for the independent testing. Independent testing facilities are approved by the Bureau of Diplomatic Security, Physical Security Programs, Physical Security Division (DS/PSP/PSD). Certification testing must be witnessed by a member of the DS/PSP/PSD.

The standards and requirements that a potential manufacturer (or its product) must satisfy in order to become qualified are found in the following documents:

  • Department of State (DOS) standard
  • SD-STD-02.01(latest revision)
  • Specification for Vehicle Crash Test of Perimeter Barriers and Gates and 12 FAH 5, Foreign Affairs Handbook
