Structure: The shield body of the PC anti-riot shield is made of 3.0mm thick PC board, with a grip and arm strap on the back.
Appearance: The surface of the shield is smooth without visible pits, bumps, bubbles, burrs, sharp corners, scratches, spots, degumming and peeling. The exposed metal structure of the shield is free of corrosion.
Grip: The grip of the anti-riot shield is easy to hold, feels comfortable, and has no defects such as burrs and sharp corners.
Protection area: not less than 0.45㎡
Shield width: not less than 500mm
Quality: not more than 2.19kg
Grip connection strength: Apply a 500N tension between the grip and the shield and keep it for 1 min. The grip will not break, loose or fall off
Armband connection strength: evenly apply a pulling force of 500N between the armband and the shield, keep it for 1min, and the grip will not break, loose or fall off
Light transmittance: light transmittance not less than 87.6%
Impact resistance: The shield body of the shield can withstand the impact of 147J kinetic energy. After the impact, the force point of the shield body must not be pierced or broken outside the radius of the force point 50mm. .
Puncture resistance: The shield body of the shield can withstand the puncture of 147J kinetic energy. After the puncture, there should be no holes larger than 6mm in the force point of the shield body or breakage outside the radius of the force point 20mm.
Impact resistance: the line speed of impact is 18 m/s±0.3 m/s, the impact energy is 342J±13J, and the shield body should not be broken or cracks larger than 50mm after the impact.
Low-temperature impact resistance: After the anti-riot shield is treated at low temperature (-30℃±2℃, 4h), the impact resistance strength test is carried out within 5in. The striking linear speed is 18 m/s±0.3 m/s, and the striking energy It is 342J±13J, and the shield body should not be broken or cracks larger than 50mm after hitting.
High-temperature impact resistance: After the riot shield is treated at high temperature (55℃±2℃, 4h), the impact resistance strength test is carried out within 5in. The striking linear speed is 18 m/s ± 0.3 m/s, and the striking energy is 342J±13J, the shield body should not be broken or cracks larger than 50mm after hitting.
