Selection method of bulletproof plate
The following factors should be taken into account when selecting:
Protection level: Priority is given to referring to NIJ standards, such as NIJ III class can withstand M80 NATO missiles, NIJ IV class needs to defend against .30-06 M2 armor-piercing projectiles 23; Chinese GA141-2010 standard also needs to pay attention to the depth of the back concave (≤ 44mm) to evaluate the impact resistance.
Scenarios of use: Ceramic composite plates are recommended for military or high-risk missions; steel plates are optional for police and vehicle armor; PE plates are suitable for lightweight requirements (such as plainclothes missions) .
Cost and weight: Steel plate is the most cost-effective (about 80 yuan-300 yuan), ceramic plate is more expensive but more protective, and PE plate is lightweight but requires a higher budget.
Material verification: Preference is given to ISO 9001 certified manufacturers and verification of NIJ/GA141 test reports to avoid delamination defects.
