📋 Understanding the Ratings

DoS K-Ratings: The U.S. Department of State ratings measure the ability to stop vehicles at specific speeds. K4, K8, and K12 represent increasing levels of security, with K12 being the highest standard capable of stopping a 15,000 lb vehicle at 50 mph.

ASTM F2656 Standard: The American Society for Testing and Materials standard provides similar ratings (M30, M40, M50) along with penetration ratings (P1-P4) that measure how far a vehicle’s cargo area penetrates beyond the barrier after impact. Lower P-ratings indicate better performance.

Our Certification: ZOD Entrance bollards are available with certifications up to K12/M50/C750 standards, ensuring maximum protection for high-security installations including government facilities, military bases, embassies, and critical infrastructure.
