Second, the helmet can be weighed. The national standard for motorcycle occupant helmets GB811--2010 stipulates that the quality of full helmets should not exceed 1.60kg; the quality of half helmets should not exceed 1.00kg. In the case of meeting the requirements of the standard, helmets that are generally heavier have better quality.

Third, check the length of the strap connector. The standard requires that it not exceed 3mm inside and outside the shell. If it is rivet riveted, it can be generally achieved, and the process performance is also good; if it is generally difficult to achieve using a screw connection, it is better not to use it.

Fourth, check the strength of the wearing device. According to the instruction manual, tie the straps correctly, buckle the buckles, and pull them firmly. The straps should not be slipped, torn, torn off, and the connecting pieces fall off and the buckles loosen and break.

Fifth, if the helmet is equipped with goggles (full helmet must be equipped with) you should check its quality. First of all, there should be no appearance defects such as cracks and scratches. Secondly, the lens itself must not be colored. It should be a colorless and transparent polycarbonate (PC) lens. Plexiglass lenses are never used.

6. Use a fist to forcefully press the inner buffer layer of the helmet. There should be a slight rebound effect. It is neither hard nor pitted or dregs.
