EN12492 Impact / Shock Absorption Similar to both industrial  helmets  and bump caps, mountaineering helmets are subjected to an impact from a falling mass onto a fixed headform. However, to reflect the nature of the use, additional impacts are required at the front, side and rear of the helmet. These impacts are carried out by tilting the headform on the rigid base at an angle of 60° (so that impacts are carried out at 30° from the horizontal plane of the headform). Impacts are carried out using two strikers, one flat and one hemispherical, each weighing 5kg. Helmets are impacted using the hemispherical striker dropped from a height of 2 metres, and at the front, rear and sides using the flat striker dropped from a height of 500mm. In all cases, the transmitted force through the headform cannot exceed 10kN. Penetration As with industrial helmets and bump caps,  mountaineering helmet  are intended to provide protection against sharp / pointed objec...

Helmet Cooling System And Design

图片
BASICS Helmet  liners are made of foam that holds heat well. Human bodies use the head to radiate excess heat during exercise. Only a flow of air over the head can carry that heat out of the helmet, so ventilation becomes critical in hot weather, and is needed even in cold weather to carry moisture away. Back in the 1980’s a British university study found that the larger the front vents, the cooler the helmet. More recent research indicates that for optimal cooling the air also needs to be channeled to the exits, so the interior channels are important to taking in the most air possible through the front vents. In some designs air may even prematurely exit through the side or top vents before performing its cooling role, and researchers have covered some vents and actually improved cooling performance. Some air flows under the edges of the helmet if you have not sealed the edge against your head with fit pads. In short, the interaction of the vents and channels in directing th...
