 MIL-HDBK-1013/14
8.2.10.2 Testing. Sandia National Laboratories tested a barrier, consisting of a chain link
fence reinforced with a 3/4-inch (1.9-cm) cable. In this test, a 3,350-pound (1,523-kg) vehicle,
traveling at 23.5 mph (38 kph), penetrated the barrier 7 feet (2.1 m). A 4,050-pound (1,841-kg)
vehicle, traveling at 50.6 mph (82 kph), penetrated 26 feet (7.9 m). Engineering analysis of
various cable restraint configurations, using the BIRM computer model (PDC-TR90-2), is shown
in Table 15.
