What Are The Technical Parameters Required For Riot Shields?

Riot shields are widely used for safety protection in schools, stations, mines, and other areas. There are many styles of riot shields, especially those made of economical and practical PC materials, due to their high transparency, good toughness, and resistance to impact and chopping. So, do you know what technical parameters are required for riot shields?
The technical parameter requirements for riot shields are as follows:
1. Structure: The shield consists of a shield body and a gripping device. The shield body is made of 4.5mm thick PC board, and the reinforced edges around the shield body are made of 6.5mm thick PC material. The back is a gripping device, consisting of a grip and an arm strap.
2. Shield emblem: The front of the riot shield corresponds to the position of the gripping device, with Chinese "Police" and English "POLICE" fonts in bold, with a height of 85mm ± 4mm; The font for "POLICE" in English is Arabic Black, with a height of 55mm ± 3mm.
3. Shield protection area ≥ 0.45 square meters
4. Specification: S (small): 900 (length) x 500 (width) x 4.5mm (thickness) (± 0.5mm)
5. Translucency ≥ 88%
6. Weight ≤ 3.1kg
7. Grip connection strength: The connection between the grip and the shield body should be able to withstand a tensile force of 500N without any breakage, looseness, or detachment.
8. Impact strength: The riot shield should be able to withstand an impact of 147J kinetic energy. After the impact, the force point of the shield should not penetrate or rupture beyond the radius of 50mm. Puncture resistance.
The shell of riot shields is usually made of high-strength and wear-resistant materials, such as polycarbonate, polypropylene, etc. The technical parameter requirements for riot shields are mainly the ones introduced above, and we all need to understand these technical parameters on our type of shield.
