How is Body Armor Rated

Body armor is rated based on its ability to stop specific types of ammunition. Rating body armor helps you choose the proper protection for your needs. If you are looking for protection but need to know how to choose your body armor, NIJ (National Institute of Justice) settled these standards in the United States. These standards ensure that the body armor meets the right testing criteria.


The NIJ Rating System


Following are the NIJ body armor classifications: 

 

Several levels provide a specific degree of protection.


Armor Level Protection Description
Level IIA Protects against low-velocity handguns like 9mm and .40 S&W.
Level II Offers protection against higher-velocity handgun rounds, including .357 Magnum.
Level IIIA Shields against high-velocity handgun rounds and select fragmentation threats, such as .44 Magnum.
Level III Designed to stop rifle rounds like 7.62mm FMJ and 5.56mm FMJ.
Level IV Provides the highest level of protection against armor-piercing rifle rounds like .30-06 M2 AP.

Each level signifies the armor’s capability to resist specific rounds at designated velocities. For example, Level III armor can stop rounds from military rifles, while Level IIA is suitable for lower-caliber handguns.


Testing Protocols

 

Body armor undergoes extensive testing at accredited laboratories to ensure compliance with NIJ standards. The testing evaluates the armor’s effectiveness in stopping specified ammunition types, focusing on factors like:


  • Backface Deformation: This measures how much the armor deforms upon impact, which is crucial for preventing blunt force trauma.
  • Velocity and Distance: The armor is tested at specific distances (5 meters for Levels IIA, II, and IIIA; 15 meters for Levels III and IV) to withstand bullets fired at designated speeds.
 

Factors Influencing Body Armor Performance

 

Several factors can affect body armor performance:


  • Material: Common materials include Kevlar, polyethylene, and ceramic. Each material has its own strengths, such as weight, flexibility, and resistance to specific threats.
  • Design: The shape and fit of the armor are critical. Properly designed armor should cover vital areas while allowing for movement.
  • Maintenance: Regular care, including cleaning and proper storage, is essential to maintain the armor’s protective qualities.
  • Wear and Tear: Over time, body armor can degrade. Regular inspections are necessary to ensure it remains effective.

 

Choosing the Right Body Armor

 

When selecting body armor, consider the following:


  • Threat Assessment: Understand the specific threats you may face and choose armor that provides adequate protection.
  • Comfort and Fit: Ensure the armor is comfortable and fits well to avoid restricting movement.
  • Durability: Opt for armor made from high-quality materials that can withstand regular use.
  • Manufacturer Reputation: Choose products from reputable manufacturers known for their commitment to quality and safety.

 

FAQs

 

1) How often should I replace my body armor?

Armor typically has a lifespan of about five years, but it should be replaced sooner if it shows signs of wear or damage.


2) Can body armor protect against knives?

Some body armor is specifically designed to resist knives and sharp objects. Still, not all armor provides this level of protection.


3) Is body armor legal for civilians?

In most states, civilians can legally own body armor, but it’s essential to check local laws for specific regulations.


Conclusion

 

Understanding how body armor is rated is vital for making informed decisions about personal protection. 


You can choose the proper armor for your needs by considering factors like material, design, and manufacturer reputation.
