Class 4 armor plates (NVMPE +Al₂O₃) L

The Level 4 protective plate is designed for installation in compatible carriers and provides torso protection against the threat types specified in its technical documentation. The size L model measures 26 × 33 cm and is recommended for a chest circumference of 111-118 cm. One plate weighs 2.9 kg and has a thickness of 25 mm. Its protective construction combines a silicon carbide SiC ceramic layer, an ultra-high-molecular-weight polyethylene backing, and polyethylene foam cushioning layers. An anatomical curve across two planes positions the plate closer to the torso. The Shooter’s Cut shape provides additional space for arm movement and equipment handling.

Level 4 Protective Plate According to DSTU 8782:2018

The model has protection level 4 according to DSTU 8782:2018. Its stated specifications include resistance to 5.45 × 39 mm PP and 7.62 × 54 mm LPS test projectiles at defined velocities. When selecting a protective component, refer to its markings, accompanying documents, and certification test conditions.

Stated test types and parameters:

• 45 × 39 mm PP, index 7N10;
• 45 × 39 mm test velocity: 910 ± 15 m/s;
• 62 × 54 mm LPS, index 57-N-323s;
• 62 × 54 mm test velocity: 850 ± 15 m/s;
• protection level 4 according to DSTU 8782:2018.

The protection level applies to the test conditions defined by the standard. Actual performance depends on the impact type, velocity, distance, angle, plate condition, and previous damage. After a severe impact, fall, or direct strike, the protective component should be removed from service and submitted for professional inspection.

Which Test Projectiles Is the Plate Rated Against?

According to the stated specifications, the Bronyx plate is designed to resist 5.45 × 39 mm PP 7N10 and 7.62 × 54 mm LPS 57-N-323s test projectiles. These parameters correspond to the stated level 4 under the Ukrainian DSTU 8782:2018 standard.

A separate test velocity and backface deformation depth are specified for each impact type. This measurement describes the maximum inward deformation of the rear surface after impact under the defined test conditions.

Stated maximum backface deformation:

• for 5.45 × 39 mm PP: 0 mm;
• for 7.62 × 54 mm LPS: 24 mm.

These results should be assessed together with the testing method and certification documents. They apply to a specific model, configuration, and controlled test conditions. The owner should inspect the outer cover regularly and observe the service life specified by the manufacturer.

Multilayer Construction with SiC Ceramic and UHMWPE

The protective properties are provided by materials performing different functions. Silicon carbide ceramic receives the initial load and contributes to the disruption of the impacting element. The UHMWPE backing retains fragments and distributes residual energy across a larger area.

The plate consists of the following layers:

1. Polyethylene foam in the front section.
2. Silicon carbide SiC ceramic layer.
3. Ultra-high-molecular-weight polyethylene layer, UHMWPE.
4. Rear polyethylene foam layer.
5. Outer protective cover made from Oxford fabric.

Polyethylene foam performs a cushioning function and helps protect the internal materials from mechanical impact. The outer Oxford layer protects the construction from dirt, abrasion, and contact with the internal surfaces of the carrier. Damage to the cover requires inspection because moisture and impacts may affect the ceramic layer.

Size L and Carrier Compatibility

The protective plate measures 26 × 33 cm. Size L is recommended for users with a chest circumference of 111-118 cm. This parameter provides an initial indication of fit, while final positioning depends on the carrier construction and shoulder strap adjustment.

Before ordering, check:

• the width and height of the internal carrier compartment;
• the permitted thickness of the protective component;
• the shape of the upper pocket corners;
• the presence of a secure lower flap;
• the plate position relative to the chest;
• whether the carrier can be adjusted after installation.

The compartment should hold the plate firmly and prevent displacement during movement. An oversized pocket may allow the protective component to drop or shift while running or bending. After installation, test the fit while standing, sitting, and lying down.

Shooter’s Cut Shape

Shooter’s Cut refers to the trimmed upper corners of the protective plate. This geometry provides more space around the shoulders and helps preserve arm mobility. The shape suits users who work with equipment attached to the front panel of the carrier.

The upper cutouts simplify forward arm movement, changes in torso position, and movement at the shoulder joint. The coverage area depends on the plate size and shape. Selection should account for the balance between protected area, weight, and mobility.

Two-Plane Plate Curvature

The model has curvature across two planes, following the main contours of the chest. The curved surface distributes pressure more evenly and reduces how far the plate projects from the torso. This affects carrier fit during extended wear.

The plate must be installed with the correct side facing the wearer. Manufacturer markings should remain legible after placement inside the compartment. When the front and rear surfaces are marked, their orientation must not be reversed.

Plate Weight and Thickness

One size L plate weighs 2.9 kg. A set of two plates weighs approximately 5.8 kg, excluding the carrier, side protection, pouches, and other equipment. When assembling a set, consider the total load on the shoulders and torso.

Main physical parameters:

• size: L;
• dimensions: 26 × 33 cm;
• recommended chest circumference: 111-118 cm;
• thickness: 25 mm;
• weight of one plate: 2.9 kg;
• approximate weight of two plates: 5.8 kg;
• curvature: two planes;
• shape: Shooter’s Cut.

The 25 mm thickness must be considered when checking compatibility with the carrier compartment. After installing a pair of plates, readjust the cummerbunds and shoulder straps. Soft shoulder pads may reduce localized pressure during extended wear.

How to Install the Protective Plate Correctly

The upper edge of the front plate should cover the upper chest area according to protective equipment positioning guidelines. The rear plate should be placed at a corresponding height so both components remain correctly positioned during movement. The lower pocket flap must secure the protective component completely.

After installation:

1. Check the orientation of the front and rear surfaces.
2. Secure the lower compartment flap across its entire width.
3. Adjust the height with the shoulder straps.
4. Set the cummerbund tension.
5. Check the plate position while walking and bending.
6. Confirm that the pouches do not displace the protective plate.

Adjustment should be completed with all protective components and the main equipment set installed. The plate should remain stable, while the carrier should allow unrestricted breathing and arm movement. Check the fit again after changing pouches or adding side protection.

Storage and Condition Inspection

Ceramic protective plates require careful handling during transportation and storage. A hard fall may damage the internal layer even when the outer cover appears intact. During transportation, use a compatible carrier or protective packaging that limits impacts.

During inspection, check:

• integrity of the outer Oxford covering;
• absence of cuts, punctures, and tears;
• condition of the edges and corners;
• absence of visible deformation;
• legibility of the markings;
• service life stated by the manufacturer.

Store the plate in a dry place under the temperature conditions specified by the manufacturer. Avoid placing heavy objects on it or allowing prolonged contact with water. A professional inspection is required after a fall, severe impact, or detection of damage.
