In order to allow consumers to fully understand the market in the sale of motorcycle, e-bike passenger helmets safety and performance, recently, this site carried out a motorcycle, e-bike helmet comparison test. The test showed that most of the samples without goggles, affecting the safety of the driver’s and rider’s facial protection; 3 samples to absorb the collision energy does not meet the standard, the shell rupture phenomenon in the test.
The comparative test samples are randomly purchased by staff as an ordinary consumer from the physical store, a total of 5 samples, involving 5 brands.
Helmet wearing device strength standards require that after the test shall not appear after the elongation of more than 25mm or tie tear tear, connectors off and buckle loose phenomenon. The elongation of one of the helmets exceeded 25mm after the test, and the other caused the phenomenon of connectors falling off after the test.
In the helmet to absorb impact energy (low temperature) test, three helmet samples in the test process of shell rupture phenomenon, does not meet the standard requirements.
Helmet samples in the helmet puncture resistance performance test, there is a steel cone through the helmet and head type contact and crack shell rupture phenomenon, does not meet the standard requirements.
From the results of this comparative test, motorcycle, electric bicycle helmets part of the structure is simple, only by a layer of plastic shell, plastic skeleton and harness composition, part of the helmet there is a lack of the key role of the cushioning layer liner and other phenomena, so that in the process of impact can not be very good to play the role of head protection.
Motorcycle, electric bicycle helmet industry confusion, uneven quality, making many manufacturers in the production process of jerry-building, low product quality and other phenomena. From the industry development point of view, one is the existence of enterprises to reduce costs at the expense of quality. For example, some companies produce helmets are not equipped with a buffer layer, reducing the protective performance. Secondly, some enterprises focus on the appearance of the design and ignore the important structural design. Third, there is the phenomenon of imitation, resulting in a certain degree of homogenization.
Consumption reminder
Choose a helmet with a cushioning layer
In response to the new problems in the sampling, this site to remind consumers, do not buy no production companies, no implementation of standards and other information, “three no” products. Do not buy only vacated plastic parts of the structure of the helmet, or helmet shell outside with the protruding parts of the product, to choose a cushioning layer of the helmet. Do not buy helmets with too narrow a belt width, belt buckle material is too soft products.
When using a helmet, wear a helmet that is comparable to the size of your head, and tighten the tether strap, which should be wide enough, generally more than the width of an adult’s thumb. Check whether the lock buckle is fastened firmly, easy to unlock, hands feel the stability of the helmet parts, to avoid the helmet out of the head to lose the protective effect. Move up and down the goggles and other devices, must be flexible and reliable, goggles should be no cracks, scratches, colorless and transparent.
Pay attention to the storage environment and service life of the helmet. Daily storage as far as possible placed in a cool ventilated place, avoid direct sunlight and contact with acids, alkalis, organic solvents. Plastic helmets should not be used for more than 3 years, and carbon fiber helmets should not be used for more than 5 years.
