What Tests Are Required For Bulletproof Vests And Bulletproof Helmets

Test one, ballistic performance test

Bulletproof is the first indicator of safety. The test was carried out in a ballistic laboratory. The test used real guns and live ammunition. The sound of the guns was so loud that the ears couldn't stand it.

The shooting range management is very strict, except for the two shooters, no one is allowed to touch the gun. The shooter does not need a scope to hit anywhere with his middle finger.

There is a safety glass in front of the shooter, which is to prevent ricochet and protect the shooter's safety.

There is also a bullet speedometer in the middle of the trajectory.

According to the requirements of the national standard, the ballistic performance test must be carried out at the specified bullet speed, so the bullet speed is a very important indicator.

Inside the body armor is a cement made of special materials to simulate human muscle tissue. Therefore, there are strict requirements on the softness and hardness of the cement during the actual measurement.

The standard stipulates that a total of 6 parts of a body armor should be tested. For every shot fired, the depth of the crater must not exceed 25 mm, otherwise the impact force will be too great and it will cause great damage to the human bones. At the same time, it is also necessary to simulate high temperature and low temperature environments in combination with actual combat scenarios for testing.

Some bulletproof vests are of substandard quality and penetrate directly into the cement, even the iron plate is punched through, causing great harm to police officers.

Test two, weight test

Although there is no requirement in the national standard, weight is an indicator for considering the portability of bulletproof products. So this time the comparison also added it, and the weighing of the body armor is only its protective layer, such as steel plate, etc., and the cloth such as the lining does not calculate the weight, and strives for the greatest fairness and justice.

Test three, protection area

The test of the protective area is to use the method of several grids, one grid is 1 square centimeter, and finally how much protective area a piece of body armor has.

And finally, calculate the "area density" based on the weight and the protective area. The smaller the area density, the better the performance.

Test four, comfort test

Comfortability includes softness, size adjustment function, shoulder cushioning and slip resistance, breathability, tactics (whether it has a portable tactical template design) and other indicators. The test methods and requirements of different levels of body armor are different.

Finally, according to the comparison results, according to different bulletproof levels, the ranking comparison results are announced to the public.
