Recently, as the "One Helmet and One Belt" safety guard operation has been carried out across the country, the topic of helmets has also become a new hot spot during the epidemic. However, the increasing demand for motorcycle helmets for safety helmets is in sharp contradiction with the backward safety regulations of the domestic motorcycle helmet industry. Under the premise of increasing demand, low-end helmets and inferior helmets are flooding in the market, with uneven quality and high prices. In fact, in October 2017, the General Administration of Quality Supervision, Inspection and Quarantine, and the China National Accreditation Administration issued the Announcement on the Transition Period for Compulsory Product Certification Management for Motorcycle Passenger Helmets, Electric Blankets and Mopeds (No. 86 of 2017) requiring From November 1, 2017, the mandatory product certification management of motorcycle occupant helmet products will be officially implemented. From August 1, 2018, motorcycle occupant helmets that have not obtained CCC certification may not be shipped, sold, imported or engaged in other business activities. Use.

Qualified motorcycle occupant helmets must pass the certification test stipulated in the mandatory national standard "Motorcycle occupant helmets" (GB 811-2010) and pass the corresponding factory quality assurance ability audit before they can pass the mandatory product certification (CCC Certification). When choosing a helmet supplier, a motorcycle manufacturer can verify the factory's CCC certification and product quality test report; when purchasing a helmet, users can identify it by the "CCC" logo pasted on the helmet, do not use it without CCC certification Helmet.

According to different shapes and structures, there are two types of helmets: full helmets and half helmets. The main difference between the two is the protection scope. Compared with half helmets, full helmets increase the protection of the lower jaw. According to different applicable objects, helmets can be divided into two categories: A helmets and B helmets. A helmets are suitable for motorcycles with a total displacement of more than 125cc. They are available in full helmets and half helmets; B helmets are suitable for general helmets. Motorcycles with a displacement of less than 125cc are smaller in volume and weight than Class A helmets, and all of them are half helmets. In general, the protection scope and protective performance of Class A helmets are better than those of Class B helmets.

【National Standard for Motorcycle Helmets】

The CCC testing standard for motorcycle helmets "GB 811-2010 motorcycle occupant helmet", the specific testing items are as follows:

【Key performance of motorcycle occupant helmet】

It mainly reflects the helmet's ability to absorb impact energy and reduce head injury when impacted. During the test, it is necessary to drop the helmet fixed on the head mold (simulating the human head) from a specified height, and assess 1 phenomenon and 2 technical parameters. Taking the A-type helmet as an example, the helmet shell must not crack after the test Phenomenon, the peak acceleration (characterizing the impact force) transmitted to the head model after collision should not exceed 300g, and the action time (characterizing the duration of noxious impact) when the acceleration exceeds 150g should be less than 4ms.

Crash test data

2. Penetration resistance

mainly reflects the helmet's ability to prevent damage to the head when it encounters sharp objects. In the test, a steel cone with a mass of 3 kg, a diameter of 25 mm, and a cone angle of 60° is used. The steel cone is dropped from a specified height (3 m for type A helmets) to carry out a penetration test on the helmet. After the test, the steel cone must not penetrate the helmet and come into contact with the head shape, and the helmet shell must not have cracks. The test results are shown in Figures 5 and 6.

[CCC certification process for motorcycle helmets]

The main reason why motorcycle helmets have evolved from production license management to mandatory certification (CCC certification) management is that these three types of products such as motorcycle helmets are directly related to human health and safety. Compulsory certification management is more conducive to protection Product quality and people's life safety. With the implementation of the mandatory 3C certification of domestic helmets, the quality of helmets is expected to pick up.
