Trauma plates are an essential part of protective equipment for many professionals in law enforcement, military, and the security industry. But what does it really mean when something is NIJ-certified, and why is it so important?
In this article, we will review what NIJ-certified trauma plates are, what threat levels they protect against, and what you should be aware of when purchasing this type of protection.
In this article, we will review what NIJ-certified trauma plates are, what threat levels they protect against, and what you should be aware of when purchasing this type of protection.
What are Trauma Plates?
Trauma plates are protective plates with a rigid construction, typically made from materials such as steel, ceramic, or Ultra High Molecular Weight Polyethylene (UHMWPE). These plates are designed to stop high-velocity projectiles, primarily from rifles. The plates work by spreading the force of the projectiles' impact over a larger area, reducing the risk of penetration and serious injury.
Trauma plates are often used as part of a complete ballistic system and offer effective protection against multiple threats, making them indispensable in many situations within both civilian and military and law enforcement applications.ICW and SA - What does it mean in relation to trauma plates?
-
ICW (In Conjunction With) means that the hard armor plates you use are designed to be used in conjunction with a soft armor vest. This means that the plates do not provide full protection alone, but only when combined with a soft armor vest do they achieve their maximum protection level. The soft armor vest helps absorb some of the energy from a shot, allowing the hard armor plate to withstand higher threat levels.
- SA (Standalone) means that the hard armor plates can provide full protection on their own, without needing a soft armor vest to function effectively. The plates are designed to withstand the specific threats they are classified for, independently of a soft vest. This makes SA plates a practical choice when one only wants to use a single protective component.
Protection levels
NIJ classifies protection levels from Level IIIA to Level IV for hard armor:- Level IIIA: Stops most pistol calibers, but not rifle projectiles.
- Level III: Protects against medium-level threats, including rifle calibers such as 7.62x39 mm.
- Level IV: The highest level that stops armor-piercing ammunition such as 30.06 AP.
Why is NIJ certification important?
NIJ (National Institute of Justice) is an American organization that sets standards for testing and quality of protective equipment. A NIJ certification means that the product has been thoroughly tested and meets strict performance and durability requirements. With a NIJ-certified hard armor plate, you get:
- Documented protection: You know exactly which threats the plate can stop.
- Reliability: Certification ensures that the product has undergone extensive testing to ensure quality and durability.
- Confidence: You can trust that the plates will perform when it matters.
Multi-Curve vs. Single-Curve Plates
-
Single-Curve Plates are flat but have a single curved shape that adapts to the body's contours. They are simpler to manufacture and have a more general fit. This type of plate is a good choice for individuals with an average body shape who do not need a tailored fit.
- Multi-Curve Plates have multiple curved shapes, providing a more precise fit that follows the body's natural contours. This type of plate is more comfortable to wear for longer periods and is often preferred by individuals who need maximum freedom of movement and comfort, such as military personnel or police officers.
Choosing the right protection
When choosing hard armor, it is important to consider:- The threats you expect to encounter.
- Weight and comfort.
- The lifespan and certification of the plate.
Materials in Trauma Plates
The materials used in trauma plates determine both the level of protection and comfort:- UHMWPE (Ultra High Molecular Weight Polyethylene): A lightweight and strong material that provides effective protection against handguns and rifles. It is ideal for lightweight, portable bulletproof vests.
- Alumina (Al₂O₃): A hard ceramic material that effectively stops rifle projectiles. Alumina is used in protective systems that require high protection against rifles.
- Silicon Carbide (SiC): A very hard ceramic material that effectively stops high-velocity projectiles and armor-piercing ammunition. SiC is often used in systems that require high protection against serious threats.
