CRASH RATED FOCUS
Crash standards are the benchmark for hostile vehicle and pedestrian error protection.
ACTIVE VEHICLE BARRIERS
Roads and vehicles are all engineered for safety. Standards make sure that performance is the same regardless of the manufacturer. There are a series of standards that evaluate the stopping power of various barriers and boundaries -- however when it comes to crash barriers there are several rating systems.
Barriers built explicitly to protect perimeters from head-on crashes are often called "anti-ram" barriers. These include bollards, fences, wedge barriers and drop beams.
In order to evaluate the effectiveness of a barrier, the Department of Defense developed a "K-rating" system back in the 1980s. This became the standard in AVB crash rating.
The utility of anti-ram barriers became more commonplace. Every day, an average of over 60 vehicles crash into storefronts, causing serious injury and property loss. This led to a need for a more civilian focused design aimed at protecting people. This started the ASTM International (American Society for Testing and Materials) to being testing and certifying anti-ram barriers. There are two major ASTM standards available currently, for high-speed and low-speed crashes.
