Armor Type
| TYPE
II (HIGHER VELOCITY .357 MAGNUM; 9MM) |
|
This
armor protects against .357 Magnum jacketed soft-pointed
bullets, with nominal masses of 10.2 (158gr), impacting at a
velocity of 425m/s (1395ft/s) or less, and against 9mm
full-jacketed bullets with nominal velocities of 358m/s
(1175ft/s). It also protects against most other factory loads in
caliber .357 Magnum and 9mm, as well as the Type I and Type IIA
threats.
Type II body armor is heavier and more bulky
than Type I and Type IIA. It is worn full time by officers
seeking protection against higher velocity .357 Magnum and 9mm
ammunition.
|
| TYPE
IIIA (.44 MAGNUM; SUB MACHINEGUN 9MM). |
|
This armor protects
against .44 Magnum, lead semi-wadcutter bullets with gas checks,
nominal masses of 15.55g (240gr), impacting at a velocity of
426m/s (1400ft/s) or less, and against 9mm full-metal jacketed
bullets with nominal masses of 8.0g (124gr),impacting at a
velocity of 426m/s (1400ft/s) or less. It also provides
protection against most handgun threats, as well as the Type I,
Type IIA and Type II threats.
Type IIIA body armor provides the highest
level of protection currently available in concealable armor and
is generally suitable for routine wear in many situations.
However, agencies located in hot, humid climates should evaluate
the use of Type IIIA armor.
|
| TYPE III
(HIGH-POWERED RIFLE). |
| This armor, normally of a hard semi-rigid
construction, protects against 7.62mm full-metal jacketed
bullets (U.S. Military designation M80), with nominal masses of
9.7g (150gr), impacting at a velocity of 838m/s (2750ft/s) or
less. It also provides protection against threats such as 223
Remington (5.56mm FMJ), 30 Carbine FMJ, and 12-gauge rifle
slugs, as well as the Type I, Type IIA, Type II and Type IIIA
threats.
Type III body armor is clearly intended only for tactical
situations when the threat warrants such protection, such as
barricade confrontations involving sporting rifles.
|
| TYPE IV (ARMOR-PIERCING
RIFLE). |
| This armor protects against .30-06 caliber
armor-piercing bullets (U.S. Military designation APM2), with
nominal masses of 10.8g (166gr) impacting at a velocity of
868m/s (2850ft/s) or less. It also provides for at least
single-hit protection against the Type I, Type IIA, Type II,
Type IIIA and Type III threats.
Type IV body armor provides the highest level of protection
currently available. Because this armor is intended to resist
"armor-piercing" bullets, it often uses ceramic
materials. Such materials are brittle in nature and may provide
for only single-shot protection, since the ceramic tends to
break when struck. As with Type III armor, Type IV armor is
clearly intended only for tactical situations when the threat
warrants such protection.
|
| SPECIAL TYPE |
| A purchaser who has a special requirement for a
level of protection other than one of the above standard threat
level should specify the exact test grounds and minimum impact
velocities to be used, and indicate that this standard shall
govern in all other respects. |
