1.2 SYSTEM DESCRIPTION

NOTE: Performance levels are based on the following:

1. The Department of State (DoS) publication SD-SDT-02.01 Specification for Vehicle Crash Testing of Perimeter Barriers and Gates (April 1985) in which:

Impact Conditions are:

Condition Vehicle Impact Kinetic Designation Weight Speed Energy

K4 6,800 kg 48 km/h 610 kJ (15,000 lb) (30 mph) (450,000 ft-lb) K8 6,800 kg 65 km/h 1084 kJ (15,000 lb) (40 mph) (800,000 ft-lb) K12 6,800 kg 80 km/h 1695 kJ (15,000 lb) (50 mph) (1,250,000 ft-lb)

Performance Levels are:

(a) L 3.0 Vehicle and cargo are to be stopped although vehicle partial penetration and/or barrier deflection of up to 1 m (3 feet) permitted.

(b) L 2.0 Vehicle and cargo are to be stopped although vehicle partial penetration and/or barrier deflection of up to 6 m (20 feet) is permitted.

(c) L 1.0 Vehicle is disabled and does not travel more than 15 m (50 feet) after impact.

2. Prior to 2001, the Department of the Navy had its own test standard for Vehicle-Crash-Resistant Barrier Requirements. Since then, the Navy has discontinued referencing its standard and now references the DOS specification for certified vehicle barriers. This guide specification still recognizes barriers originally certified under the Navy standard. These barriers are identified as such in their respective paragraph of PART 2 PRODUCTS. The Department of the Navy publication Operational Requirement No. 098-09-88: Operational Requirements for Secure Structures Ashore (Locks and Barriers, 1986) in which:

SECTION 34 71 13.19 Page 5

Vehicle-Crash-Resistant Barrier Requirements are:

Security Vehicle Impact Kinetic Level Weight Speed Energy

HIGH 4,535 kg 80 km/h 1133 kJ (10,000 lb) (50 mph) (836,000 ft-lb) LOW 4,535 kg 24 km/h 102 kJ (10,000 lb) (15 mph) (75,000 ft-lb)

Performance Levels are:

(a) For the high security level, vehicle penetration from 0 to 3 m (0 to 10 feet) is permitted.

(b) For the low security level, vehicle penetration from 15 to 30 m (50 to 100 feet) is permitted.

3. Because kinetic energy is a function of the square of the velocity, the vehicle's speed has more significance than its weight. Therefore, limiting a vehicle's speed reduces the kinetic energy the barrier must resist resulting in a lower barrier cost. Vehicle barrier requirements are within the chart combinations below:
