In today’s world, the ballistic plates standard level, to the United States NIJ standard as the main dividing basis.This standard level of six, divided into: Level I , II A, II, IIIA, III, IV .Level I is the lowest, while Level IV is the highest.
Including level III A (3A) plates requirement can resist .44 Magnum pistol cartridge, velocity is : 440m/s. III A level below the three levels of only prevent 9 mm pistol shooting. velocity is : below 360m/s. At present most general customer request body armor of basic level of protection is III A level (3 A).
Body armor III A below level (3A) is soft, do not need ceramic plate.The bulletproof layer material of soft bulletproof insert plates is divided into ultra-high – molecular-weight polyethylene( UHMWPE ) fiber;And Kevlar.The price of bulletproof insert plates is concerned with the material used, and also concerned with the protective area.The larger the area, the higher the price.
III level (level 3) ballistic plates
Level III ballistic plate is ceramic composite bulletproof plate, the thickness of each around 20 mm;The weight is around 2.6 kg. This level is required to protect against direct fire from NATO M80 rounds.That is, a 7.62 * 51 mm projectile with a velocity of 800m/s. Also in this class are regular rounds fired from AK-47 and 56 rifles.
IV level (level 4) ballistic plates
The thickness of the protection level of the highest level IV plate thickening to 25 mm; Weighing 3.0kg, required to be able to prevent the M1 launch of the armor-piercing projectile, projectile velocity: 850m/s.
