When considering the use of security barriers to prevent forced perimeter penetration by vehicles, there are two standards that should be considered. The US K-series of ratings provides for certification of barriers that meet specific resistance requirements. For example, K-12 means that the barrier should be able to stop a vehicle with a weight not exceeding 6,800 kg at speeds of up to 80 kph.
A much more accurate assessment of your needs, however, can be made using the British Standard PAS 69:2006, which provides very useful guidance on the threat and site assessment process, identification of critical assets, choice of barrier (perimeter or access control-specific), environmental considerations, and other considerations for barrier selection. There are also annexes on specific kinds of barriers. If you are considering installing a vehicle blocking system, the document will undoubtedly help you avoid common errors and remind you of the many factors that have to be taken into consideration.
