riot helmet, material: abs&pc model no: fbk-ja03-l
1, the implementation of standards: "ga 294-2012 police riot helmet".
2, police riot helmet by the shell, buffer layer, padding, mask, wearing device (including tie, chin rest, wearing buckle and helmet top suspension system, etc.), neck protection. police riot helmets are made of materials that are non-toxic and harmless to the human body. the liner is sweat-absorbent, breathable and comfortable.
3, appearance: police riot helmet outer surface coating uniform and smooth, no impurities, blistering, peeling, flaking and other defects on the surface.
4, logo: customized.
5, cap badge: police riot helmets have a cap badge, cap badge pattern, size, color in line with the provisions of ga270, fixed position in line with the provisions of appendix a, tolerance ± 2mm.
6, color: shell outer surface color for the "9 9" type navy blue.
7, size: specifications according to gb/t10000-1988 head size, divided into l (large), m (medium), s (small) three specifications.
8、weight:1.6 0 kg.
9, shell: shell surface without obvious dents, sharp corner spikes and other defects. mask connector shell outer surface 14mm, tie and other parts of the connector does not exceed the shell inside and outside the surface of 3mm, the connector without burrs. shell edge inlaid with soft rounded blunt edges, in the corresponding part of the human ear set up through the sound hole.
10, buffer layer: buffer layer to absorb collision energy.
11, liner: liner can be removed and washed.
12, mask: mask without bump marks, sharp corners, burrs, bubbles and other defects, smooth rounded edges, no burrs. mask opening and closing process, can maintain the positioning function under the action of non-artificial external force. the diameter of any small spot or black spot on the mask is 1mm and the number is 4. light transmission rate of 88.9%, the maximum amount of light distortion 2, the inner surface has anti-fog performance.
13, wearing device: tie and shell fixed connection, the width of the tie 19.7mm. wearing buckle opening and closing function is convenient and reliable, can effectively adjust the degree of elasticity of the tie. the lanyard can withstand 900n tensile load, loading process lanyard will not tear, tear off, connectors fall off, wearing buckle loose phenomenon, lanyard elongation 15mm, unloading wearing buckle can be used normally. helmet top suspension system to ensure ventilation and easy to adjust.
14, neck guard: neck guard made of soft materials, removable, reliable connection with the shell, along the middle vector surface extending out of the police riot helmet shell outside the effective part of the length of 103mm.
15, anti-leakage performance: can withstand the spraying of test liquids, test head mold is not colored; mask in the closed, and shell joints have anti-liquid flow function.
16, impact protection performance: can withstand the mask 4.9j kinetic energy impact, after the impact of the mask and the nose of the test head mold does not contact, and the mask can be opened and closed normally.
17, impact strength performance: mask can withstand 1 g lead bullet 150 m / s ± 10m / s speed impact, after the impact of the mask is not pierced or broken.
18, absorption of collision energy performance: can withstand the impact of 49j energy, the impact of the force transferred to the test head mold is less than 4900n, and the shell does not break.
19, penetration resistance: police riot helmets can withstand 88.2j energy puncture, puncture when the falling hammer does not penetrate the police riot helmet and test head mold contact.
20, flame retardant performance: the shell of the outer surface of the continued combustion time of 4s.
21, the climate environment adaptability: at -20 ℃ ~ 55 ℃ and room temperature under the conditions of rain, the shell did not rupture, mask and test the nose of the head mold did not come into contact with and can be opened and closed normally. the performance of collision energy absorption meets the requirements.
