BALLISTIC LEVELS

Ballistic levels of protection outline the exact strength of attack each level of bulletproof body armor can protect against. As the levels go up, you will be protected from a wider range of gun threats. The levels of protection for body armor are: 

NIJ Level IIA NIJ Level II NIJ Level IIIA NIJ Level III NIJ Level IV  
Areal Density 3.5 kg/m 42.2 kg/m 5.9 kg/m 25.9 kg/m 32.5 kg/m
Thickness 4mm 5mm 6mm 15mm 20mm
.22mm short X X X X X
.9mm X X X X X
.45mm X X X X X

EDGED BLADE LEVELS

CAST standardizes stabproof vests and has identified different levels of protection for bulletproof vests. This is because although the materials in bulletproof and stabproof vests are developed in the same way, a stabproof vest requires a much tighter weave and the addition of materials like chain-mail or laminate to be effective. Multi-threat vests that can protect against ballistics and knives will still need to be graded according to the levels outlined above and below:

Knife Resistance Level 1   Knife Resistance Level 2    
Energy Level E1 E2 E1 E2
Energy (joules) 24 36 33 50
Velocity 5 m/sec 6.2 m/sec 5.9 m/sec 7.3 m/sec
Total Missile Mass 1.9 kg 1.9 kg 1.9 kg 1.9 kg
Maximum Penetration 7 mm 20 mm 7 mm 20 mm
