What are the basic technical requirements of a safety helmet?
The puncture resistance is the ability of the helmet to resist ChuangTou when it is impacted by a sharp falling object, which is the test of the strength of the shell.
Impact absorption performance refers to the ability of a helmet to absorb impact energy when it is impacted by a falling object. A better safety helmet absorbs 80%-90% in the impact absorption process to minimize the impact on the renti, so as to achieve the best protection effect. The formulation of impact absorption energy is based on the maximum impact force of the renti cervical spine. In accordance with the provisions of GB/T 2812-2006, after high temperature, low temperature, immersion, UV irradiation pretreatment shock test, the transfer of the first die on the force of no more than 4900N, the cap shell shall not fall debris.
