The K-12 rating can arrest a vehicle of up to 15,000 lbs moving at 50 mph.

SECURITY BOLLARD BASED ON THE K12 SECURITY RATING
Government and private buildings all want to ensure security and safety on their premise. To ensure safety there is the need to know the risks and potential threats associated with a particular location of any industry. You can then take necessary steps to ensuring the risks are tackled. Some of those risks can be tackled using the Security Bollard.

The Security Bollard is created specifically to serve both physical and visual protection for vehicles and pedestrians. These Bollards are placed in high-risk zones and they guard against impact from vehicles or control movement and serve as a barrier against theft.

The crash rating design can be verified by either physical test (full scale test) or by computer simulation (Engineered). However, the certificate will be issued to physical test only. Simulation test can be used if minor changes considered in the bollard after the full scale test.

A Standard Security Bollard must pass the standard crash tests before being certified for security purposes. One of such tests is the K-rated Standard which was originally created by the US Department of States in 1985 and then revised in conjunction with the Department of Defense in 2003.

The three categories of this rating standard are the K4 30 mph, K8 40 mph, and K12 50 mph.

The K-12 rating is the highest and strongest in this category with its ability to successfully arrest a vehicle of up to 15,000 lbs moving at 50 mph.

This type of Security Bollards is usually placed in the places with the highest potential risks. Of the three ratings, it is advisable to make use of the K12 standard security Bollard once you realize there are high potential risks in your environment.

While the older DOS SD-STD-02.01 standard, K-Rating,  is now discontinued, other alternative standards used to test these bollards include:

  • SD-STD-02.01 Rev. A (2003)
  • ASTM F2656-07 (2007)
  • BSI PAS 68 (2013)
  • ISO IWA 14-1 (2013)

Although these standards show bollard effectiveness in their own rating designation, it is ultimately based upon impact energy absorption capacity of the bollard.
