See the standard: although at present Electric vehicle helmet There is no national standard yet, but consumers can choose a lighter motorcycle helmet when shopping. The country has a national standard for motorcycle helmets (GB 811-2010) and CCC certification. At the same time, there are still 2 Electric vehicle helmet Group standards: one is the Group Standard for Electric Bicycle Passenger Helmets (Q_T/TXB001-2019) of Zhejiang Yueqing, and the other is the Technical Requirements and Test Specifications for Electric Bicycle Passenger Helmets (T/SEIA_003-2019) of Shenzhen. As long as consumers buy products that meet the above three standards through formal channels, they should be products with quality assurance from formal manufacturers.
Look at the appearance: the helmet is composed of shell, buffer layer, wearing device, etc. The shell shall be hard, durable and smooth, and it is better to choose an integrated shell, such as durable ABS material; The buffer layer is made of non-toxic and harmless materials that can absorb collision energy and cover the head protection area; Cushion is made of sweat absorbing and breathable materials; Goggles must meet the requirements of light transmittance and impact; The helmet edge should be round and blunt; The lacing connector should not have rough edges. It should be securely and comfortably worn, easy to release, not too thin in width, and not too elastic; The ventilation holes on the helmet shall not be too large (preferably less than 13MM) or too many. Some helmets have large and many ventilation holes, which look very breathable, but the head protection coefficient will also be reduced accordingly.
Look at the label: all helmets of regular production should have permanent marks, including product name, manufacturer name, factory address trademark, model, specification, production date, product number, conformity mark, product standard number, etc. Never buy anything without a label.
Size: When purchasing, consumers must try it on. They should choose products that are suitable for their head shape and size. They should not be too tight or loose. They should not pinch their face or shake. The weight should be based on the fact that their neck is not tired after wearing.
Buying mistake: Don't try to buy inferior plastic helmets cheaply or replace them with site helmets. The plastic helmet has no protection function, while the safety helmet on the construction site mainly protects the top of the head, only for the damage caused by falling objects, but has no protection function for the top, front and side of the head. If this helmet is used, in case of an accident, fragments will be generated after impact and rolling, which will cause secondary injury.
Attention during use: the consumer must fasten the tie when using. After using the helmet, it should be placed in a cool and ventilated place to avoid high temperature or long-term sunlight. If there is collision or slight crack during use, it should be replaced in time and should not be used again. At the same time, consumers should be reminded that helmets also have a shelf life. Most safety helmets play a role in safety protection within 3-5 years, and should be replaced regularly to avoid helmet protection failure.
