When specifying anti-ram perimeter security barriers, it is important to consider the design of each system and how they were tested to ensure they meet the applicable threat conditions.

As a result of the recent rise in vehicle-ramming attacks, there is an increased interest in perimeter security for applications besides the traditional government and military operations. From large cities, small municipalities, and grade schools to universities, utility substations, and corporate offices, many organizations are contemplating how to provide an increased measure of security with a tight budget.<\/p>\n

Given the abundance of products available on the market, and the fact many specifiers are contemplating anti-ram barrier measures for the first time, it is important to understand how to evaluate and select a perimeter security solution that best suits each unique application and budget. Beyond these considerations, working with a security professional is highly recommended to determine the appropriate threat type and level, navigate the process, and provide a holistic approach to the entire project.<\/p>\n

When researching anti-ram perimeter security barriers, serious thought should be given to how each system was designed and tested to ensure it meets the applicable threat conditions. This process can sometimes be challenging with multiple published vehicle crash testing standards and numerous crash ratings within those standards. The U.S. Department of State<\/a> (DOS) pioneered anti-ram vehicle barrier testing, and developed a rating system and test standard that was first published in April 1985 (SD-STD-02.01, Certification Standard\u2013Test Method for Vehicle Crash Testing of Perimeter Barriers and Gates<\/em>), and later revised in 2003 (SD-STD-02.01 Rev A).<\/p>\n

In 2009, the DOS retired SD-STD-02.01 Rev A and stated all new barriers should be tested to ASTM International standards to be considered for embassy projects. ASTM F2656-15, Standard Test Method for Crash Testing of Vehicle Security Barriers<\/em>, is the most recent standard to which anti-ram vehicle barriers are tested.<\/p>\n

ASTM ratings are assigned based on three variables:<\/p>\n
