Beginning February 1, 2009, the Department of State (DoS) decided to evaluate only new anti-ram barriers tested under ASTM F2656-07 Standard Test Method for Vehicle Crash Testing of Perimeter Barriers for the selection and approval for use at DoS facilities. The only barriers considered would be those with an ASTM F2656-07 rating of M30 P1, M40 P1and M50 P1. The chosen impact point must be agreed to by DoS. This ASTM standard provides a range of vehicle impact conditions, designations, and penetration performance levels that will allow an agency or owner to select passive perimeter barriers and active entry point barriers appropriate for use at facilities with a defined moving vehicle threat.
Crash testing can convincingly demonstrate the performance of a specific barrier, but it may not address site-specific important subgrade conditions and does not provide the flexibility required to engineer the foundations and barriers for adverse subgrade conditions.
The crash testing standard in common use was developed by DoS. To obtain DoS certification, the vehicle barrier must be tested by an independent crash test facility to meet DoS standards. The test specifies perpendicular barrier impact by a 15,000-lb. (6810 kg.) diesel truck. Initially, the DoS standard provided for three levels of intrusion, but in February 2003, the standard was revised, calling for the highest test level — that which allows less than 36 inches (0.9m) penetration distance. |
