The main components to be considered in protecting the user's head are to minimize the shock effect, which is generally measured as the angle of acceleration of the head. This is usually in the form of using a material such as foam to slowly absorb movement in an impact, thereby reducing the acceleration of the head.
The most suitable type of material typically depends on the type of expected hazard. This factor is based on the manufacture of helmets. For example, a soft foam can absorb smaller shock loads. For example, a ball hitting the head. In contrast, larger shock loads require an inelastic rigid foam which does not return after impact. For example, a biscuit falling and hit his head hard on the asphalt.
Since helmets are usually worn near the wearer's skin and hair, attention should always be paid to the chemical safety of materials used in helmet production. The evaluation of these materials is typically part of the process of reviewing European Union legal regulations.
Since helmets are of the type designed to protect a static user from falling hazards, helmets are subjected to a series of impact tests using a fixed head form with a falling mass striker.
For example, for a helmet to meet the EN 397 standard requirements, the maximum transmitted force should not exceed 5 kN after proper signal conditioning. This test is applied on several different helmet samples following pre-conditioning of high temperature, low temperature, immersion and UV aging.
Industrial helmets are also tested to ensure they provide adequate protection against sharp or pointed objects. During the test, a striker is dropped from a certain height onto the helmet attached to a fixed head form.
This test is based on a method similar to the shock absorption test. As in the impact test, these tests are carried out on helmets that are preset for high temperature, low temperature, immersion and UV aging.
