Commercial Crash-Rated Barriers
To determine the best perimeter security option for a site, conduct a thorough risk assessment to identify where vulnerabilities may exist and how that compares to the sites’ security objectives. A TYMETAL specialist is always available to help you choose perimeter security solutions that best fit the site’s unique requirements and characteristics.
Understanding Crash Ratings
It is important to understand Crash Test Standards before selecting a crash rated vehicular barrier. Please read our Guide to Understanding Crash Ratings and refer to the Crash Test Matrix below.
Most Commonly Used Crash Test Ratings (and how they relate to each other)
| Crash Test Standard | US DoS SD-STD-02.01 (1985) | US DoS SD-STD-02.01 Rev. A (2003) | ASTM F2656-20 (2007-current) | BSI (British Standards Institution) – PAS 68 & IWA 14 |
|---|---|---|---|---|
| Test Vehicle | 15,000 lb Medium Duty Truck 15,000 lb Medium Duty Truck | 15,000 lb Medium Duty Truck | 15,000 lb Standard Test Truck (M) | PAS 68 – 7,500 kg (16,535 lb) Cab-over Engine Medium Duty Truck IWA 14 – 7,200 kg (15,873 lb) Cab-over Engine Medium Duty Truck |
| Test Vehicle Speed | K4 = 30 mph K8 = 40 mph K12 = 50 mph | K4 = 30 mph K8 = 40 mph K12 = 50 mph | M30 = 30 mph M40 = 40 mph M50 = 50 mph | 48 kph = 30 mph 64 kph = 40 mph 80 kph = 50 mph |
| Penetration Ratings | L3 = greater than or equal to 3 ft L2 = greater than 3 ft – 20 ft L1 = greater than 30 ft – 50 ft | Must be less than or equal to 1 m | P1 = less than or equal to 1 m (3.3 ft) P2 = 1.01 m – 7 m (3.31 ft – 23 ft) P3 = 7.01 m – 30 m (23.1 ft – 98.4 ft) | Penetration distance of both vehicle and debris field are given in the classification (see interpretation below). |
| Examples | K12 (L2) – Rated to stop a 15,000 lb truck traveling 50 mph with a penetration between 3 ft and 20 ft. | K4 – Rated to stop a 15,000 lb truck traveling at 30 mph with a penetration of less than or equal to 1 m. | M40 (P3) – Rated to stop a 15,000 lb truck traveling at 40 mph with a penetration between 7.01 m and 30 m. | How to read PAS 68 classification code (see graphic below this table). |
Interpreting the PAS 68 Classification Code

* IWA 14 does not consider debris dispersion.
