Class 4 DSTU protection armor plates
Class 4 protection body armor plates according to DSTU 8782:2018 are modern personal protective equipment designed to stop assault and rifle bullets. They are used in body armor and plate carriers by military and law enforcement structures. Class 4 plates are made of steel, ceramics, or composite materials, which affects their weight and level of comfort. This level of protection offers an optimal balance between mobility and safety in combat conditions. Each plate undergoes rigorous testing and trials to guarantee its high quality and effectiveness.
According to technical specifications, this class is capable of protecting against the following calibers and ammunition:
- 5.45x39 mm caliber — used in various models of assault rifles and rifles such as the AK-74, AKS-74U;
- 7N10 bullet — a cartridge with an increased penetration (PP) bullet featuring a steel heat-strengthened core;
- 7.62x54 mm caliber — used in various types of sniper weapons and rifles;
- 57-N-323S bullet — a cartridge with a light bullet steel core (LCS/LPS) and a bimetallic case.
Testing is conducted under controlled conditions in accordance with DSTU, which includes a specified shooting distance, impact velocity, and the number of shots per sample.
Furthermore, according to DSTU, armor plates must ensure impact resistance against calibers that lower-class plates can withstand.
Class 4 ceramic armor plates. Quality criteria
✔️ Protection area — a unified size that covers critical anatomical areas of the chest and back, guaranteeing a baseline level of safety.
✔️ Class 4 protection according to DSTU — provides resistance to hits from increased penetration 5.45x39 mm caliber bullets, as well as 7.62x54 mm rifle ammunition during testing at distances established by the standard.
✔️ Weight — a crucial indicator that determines comfort during long-term wear without unnecessary strain, affecting the user's mobility and overall physical endurance.
✔️ Compatibility with plate carriers — the correspondence of the armor plate to the dimensions and design features of the carrier vest, guaranteeing a tight fit without gaps, play, or shifting during movement.
✔️ Ergonomic shape — follows body contours, ensuring a stable fit and proper weight distribution. The design is adapted for shooting — it does not interfere with shouldering a stock and does not restrict mobility in the shoulder area.
✔️ Material — features a composite construction: a ceramic layer made of silicon carbide, which destroys the bullet upon impact, and a backing energy-absorbing layer of UHMWPE, which distributes the impact load, providing product durability at a relatively low weight.

Before buying Class 4 armor plates, we advise you to consider
Plate material
The basis of most armor plates is a ceramic-composite construction: a ceramic layer combined with Ultra-High-Molecular-Weight Polyethylene (UHMWPE).
- SiC (Silicon Carbide) — the optimal balance of weight, strength, and cost.
- Al₂O₃ (Aluminium Oxide) — a more economical material, but it has a higher density, making plates made from it typically heavier.
Size and protection area
The armor plate must match the size of the plate carrier and cover the vital areas of the torso without restricting freedom of movement. Only a properly selected combination of plate and plate carrier ensures reliable fixation and effective use of protective gear.
Set weight
A properly selected Class 4 armor plate affects comfort and physical strain during wear. Lighter models help reduce fatigue and make long-distance movement easier, while heavier ones may provide other advantages depending on their design.
Compatibility with plate carriers
Before purchasing, it is necessary to consider the dimensions, shape of the armor plate (flat or anatomical), and cut type (SAPI, Shooter's Cut, etc.). This will prevent the plate from shifting and ensure its proper positioning in the plate carrier.
Comfort and ergonomics
Usability is influenced by the shape of the armor plate, its degree of curvature (Single Curve or Multi Curve), weight distribution, and tightness of fit to the body. Additional comfort is provided by anatomical construction and proper ventilation.
Conditions of use
The choice of armor plate should be made considering the nature of the tasks. For long-term wear, lighter models are usually preferred, while for short-term use or work in stationary positions, heavier options may be used.
FAQ. Frequently Asked Questions about Armor Plates
What does Class 4 protection mean?
Class 4 protection according to DSTU 8782:2018 means that the armor plate meets the requirements of the current standard for ballistic resistance. During testing, it must withstand hits from 5.45x39 mm caliber bullets (7N10 index with a steel heat-strengthened core), as well as 7.62x54R LPS bullets (57-N-323 with a steel core) under conditions established by the current standard.
Who is this level of protection designed for?
Class 4 protection armor plates are designed for users who require an increased level of ballistic resistance. They are used by military personnel, law enforcement officers, security and defense structures, and other users operating in high-risk environments.
What materials are Class 4 armor plates made of?
Most commonly, ceramics based on aluminium oxide (Al₂O₃) or silicon carbide (SiC), as well as ultra-high-molecular-weight polyethylene (UHMWPE), are used. These materials provide high protection efficiency at a lower weight compared to steel counterparts.
Do you deliver throughout Ukraine, and are products checked before shipping?
Yes. We deliver throughout Ukraine via Nova Poshta and Ukrposhta services. For convenience, cash on delivery (COD) is available, with carrier service fees paid separately. Before shipping, each item undergoes a thorough quality check and is securely packaged to minimize the risk of damage during transit.
