Ongoing current global terrorist activity threats continue to drive demand for antiterror measures. HIGH-SECURITY products (also known as HVM products) protect the infrastructure against vehicle-borne threats, creating blast stand-off distance. Since September 11th 2001, several international accreditation standards have defi ned essential impact performance requirements for a vehicle security barrier (VSB) and a test method for rating its performance.

There are essentially 2 standard families :
- US standards with the precursor DOS K-rating which has been replaced and extended by the ASTM F2656-07 standard ;
- UK created PAS68 standard which has been replaced and extended by international standard IWA14-1 (ISO).
