When choosing a helmet testing machine, which one is usually more worth choosing?

Generally, when you buy a helmet testing machine, look for a broad material testing machine. This is a device for helmet goggles for motorcycles.。

1.Each helmet should have the following four permanent markings: aManufacturer's name, trademark, model; b.Year and month of manufacture; c.Production certificate and verification; d.Production license number.

2.The service life of the safety helmet is calculated from the date of completion of the product: no more than two years for plant branch woven caps, no more than two and a half years for plastic caps and paper plastic caps, and no more than three and a half years for FRP (vinylon steel) rubber caps.

3.The weight of the helmet should be as light as possible and should not exceed 400g:a

Small brim and curled helmet: no more than 430g (excluding accessories); b.Large-brimmed helmets do not exceed 460g (excluding accessories); c.Cold-proof caps do not exceed 690g (accessories not included).

4.The minimum brim size is 10 mm and the maximum size is 35 mm. The brim inclination should be 20° to 60°.

5.There is a gap of 2 5 cm between the cap shell and the cap lining, which plays a cushioning and shock absorption effect, and can prevent the shell from being deformed by force and directly hitting the top of the head.

6.Impact absorption and penetration resistance need to be tested with specialized instruments.

Simple Detection Method:

1) Steel hammer for test: symmetrical and uniform shape, made of 45 steel, weight of 5+, hammer head hemispherical, diameter 96mm.

2) Test method: The steel hammer falls freely from a height of 1m (the distance from the bottom surface of the hammer to the top of the safety helmet) to impact the safety helmet.

3) Observation: The appearance of the helmet is intact, no damage, no deformation, and the lining is intact.

In the case of motorcycle occupant helmets, the national standard is GB 811-2010.

GB 811-2010 has corresponding provisions for motorcycle occupant helmets, defining the scope of application, objects, standard attributes, standard drafting units, standard proposing departments, etc. At present, there is no national standard for the widely produced and sold electric vehicle helmets.

Enterprises and individuals who need helmet testing can go to the "Zheli Inspection" platform, which has uploaded relevant service plans from many institutions.

The "CE" mark is a safety certification mark that is seen as a passport for manufacturers to open and enter the European market. CE stands for European Unity (Conformite Europeenne). All products with the "CE" mark can be sold in EU member states without meeting the requirements of each member state, thus realizing the free circulation of goods within the EU member states.

In the EU market, the "CE" mark is a mandatory certification mark, whether it is a product produced by an enterprise within the European Union, or a product produced in other countries, if it wants to circulate freely in the EU market, it must be affixed with the "CE" mark to indicate that the product meets the basic requirements of the EU "New Approach to Technology Harmonization and Standardization" directive. This is a mandatory requirement for products under EU law.

Helmets exported to the EU must provide CE certification.

When buying a safety helmet, you must not be greedy for cheap, and you cannot choose a safety helmet on the construction site. When purchasing, you should carefully check the product name, certificate, factory name, address, implementation standards, etc., and recognize the CCC certification。Inferior helmets not only fail to protect the head, but can even cause other secondary injuries to organs due to the fragmentation of parts caused by collisions.

However, the correct selection of high-quality helmets is only the foundation, and it is more important for traffic participants to enhance the awareness of "self-protection", and once again call on the majority of electric vehicle riders to consciously abide by road traffic safety laws and regulations.

Choose the brand, the credibility is better, and the brand products have strong inspection marks and requirements in the national certification.

For beginner players who want to buy a motorcycle, it is important to understand how to choose a simple riding protector, and talk about the choice of helmet in order from head to toe.

Now we all know that riding electric vehicles and motorcycles must wear helmets, because the protective effect of helmets for us is still very obvious, and our own safety is the most important thing for us, but many people will choose to buy helmets online when buying helmets, because for many people, the helmets sold online may be relatively cheap, but we all know that the most important thing to choose such products is quality. <>

So I think that although the price of buying helmets online is very cheap, the quality is often not guaranteed, although it is said that such a product is very good in the mouth of the seller, but when you really receive such a product, it may not be the seller's mouth. <>

So we must pay attention to the quality of the helmet when buying a helmet, if the quality of the helmet can not be guaranteed, then we have no meaning to wear a helmet, which is naturally a very unsafe thing for us, in now we can find that a lot of traffic accidents are caused by not wearing a helmet, because if you do not wear a helmet collision, it is naturally very dangerous for us, If you are involved in a traffic accident while wearing a helmet, you can at least ensure that your head will not be injured, which is very important for us. <>

Because once we hit our head, it will naturally be a very serious accident for ourselves, and even such an accident will threaten our lives. Therefore, when we choose a helmet, we must go to the best helmet store to choose, only by making such a choice will you know that the quality of the helmet is very different, for us to pay attention to the quality of the helmet when choosing such a product is naturally a very important thing. So I think we all need to pay attention to our own safety, and never let our bodies be hurt for a little cheapness.

Choose a helmet from a regular manufacturer. To choose a good helmet, don't be greedy, but don't pursue expensive ones too much, but choose regular manufacturers according to demand.

We should go to a regular *** to buy helmets, not to some third-rate brand stores to buy helmets, and when buying helmets, we should try them on first to ensure the comfort and quality of helmets.

If you want to choose a good helmet, you must first look at its material, and try to choose a helmet with good material.

That is, when we buy helmets online, we must see how many stars the evaluation of this store is, if it reaches 4 and a half stars or more than 4 stars, it means that its quality is better, and it also depends on sales, if the sales are particularly good, it means that the quality is very good, and it also depends on people's evaluations.
