Studies have shown that most of the deaths in road traffic accidents involving motorcycles are caused by head injuries. If safety helmets are used correctly, they can greatly reduce the direct injury to drivers and riders in accidents and effectively reduce the mortality rate of motorcycle accidents.
At the same time, it should be noted that in actual use, the inferior helmet not only fails to play a due role in the protection of the head, but may even break the parts due to the collision, thus causing other secondary injuries to the organs.
Therefore, the use of qualified motorcycle helmet is the key to ensure the safety of motorcycle driving.
Introduction to motorcycle Rider helmet
According to the different shape and structure, there are two kinds of helmets, full helmet and half helmet. The main difference between them is the different protection scope. Compared with half helmet, full helmet has more protection for the lower jaw.
According to different objects of application, helmets can be divided into Type A helmet and Type B helmet. Type A helmet is suitable for motorcycles with A total exhaust capacity of 125cc or above and has two shapes: full helmet and half helmet. Class B helmets are suitable for motorcycles with A total exhaust capacity below 125cc. Their size and weight are all smaller than class A helmets, and all shapes are half helmets.
Generally speaking, type A helmets have better protection range and performance than type B helmets.
Quality control requirements for motorcycle rider helmets
National standard: In order to standardize and improve the product quality of motorcycle rider helmets, the Ministry of Public Security has put forward and centralized the national standard. The Institute of Traffic Management Science of the Ministry of Public Security is responsible for formulating mandatory national standard. The current standard version is Motorcycle Rider Helmet (GB 811-2010). GB 811 standard puts forward a series of requirements such as technical requirements and test methods for helmets from the perspective of ensuring crew safety.
CCC certification: in October 2017, issued by general administration of quality supervision, inspection and the national Certification and Accreditation Administration released on the helmet, riding motorcycles, electric blanket, moped products turn announcement of mandatory product certification management transition arrangement (2017) no. 86, formal requirements in November 2017 01 mandatory product certification for motorcycle helmet crew product management, August 1, 2018, motorcycle helmet crew didn't get the CCC certification, not factory, sell, import or use in other business activities.
National Standard and CCC Certification rules for Motorcycle Rider Helmets
Quality identification: Motorcycle rider helmets with qualified quality shall pass the certification test stipulated in the mandatory national standard motorcycle Rider Helmet (GB 811-2010), and then pass the mandatory product certification (CCC) after the corresponding factory quality assurance capability audit.
When choosing helmet suppliers, motorcycle manufacturers can check the FACTORY's CCC certificate and product quality test report; When users buy helmets, they can be identified by the "CCC" logo pasted on the helmet, and do not use helmets that have not passed CCC certification.
The key performance of the motorcycle rider helmet
Strict technical detection is the key link of the helmet quality safety, according to "the motorcycle helmet crew" (GB 811-2010), qualified motorcycle helmet crew need through the "view", "goggles" and "rigidity", "absorb collision energy performance" and "penetration resistance" ten projects such as detection, among them, the "absorb collision energy performance" and "penetration resistance" is the representation of the helmet safety performance indicators.
Ability to absorb impact energy: it mainly reflects the helmet's ability to absorb impact energy and reduce head injury when impact occurs. During the test, the helmet fixed on the head mold (simulating the head of human body) shall fall from the specified height, and 1 phenomenon and 2 technical parameters shall be examined.
For example, after the test, there should be no cracks in the helmet shell, the peak acceleration (representing the impact force) of the transmitted headmold should not exceed 300g after the collision, and the action time (representing the duration of the damaging impact) of the acceleration exceeding 150g should be less than 4ms.
Collision test data
Penetrability: it mainly reflects the helmet's ability to prevent penetrating damage to the head when it encounters sharp objects. During the detection and test, A steel cone with A mass of 3kg, A diameter of 25mm and A cone Angle of 60° was used to fall from the specified height (class A helmet was 3m) to carry out the penetration test on the helmet.
After the test, the steel cone shall not penetrate the helmet and make contact with the head shape, and the helmet shell shall not have cracks.
Proper use of helmets is crucial to motorcycle driving safety. CCC certification is only the basis for improving product quality. It is more important for traffic participants to enhance their awareness of "self-protection".
The majority of motorcycle drivers and riders should set up "do not wear a helmet do not ride a motorcycle" "wear a safety helmet" safety awareness, while driving "chasing the wind", do not forget the head "safety protection"!
