Ballistic materials are rated based on international standards such as NIJ, STANAG 4569, EN 1063 (glass resistance), and EN 1522 (material resistance). These define protection levels against various ballistic threats.
- NIJ Level III stops high-velocity rifle rounds like 7.62×51mm and 5.56mm.
- NIJ Level IV protects against armor-piercing rounds such as .30-06 M2 AP.
- STANAG 4569 is used for military vehicle armoring against high-caliber threats.
For lightweight solutions, composites and layered systems offer protection with less weight.
