The main principle of ,safety helmet, is to protect workers against impact by falling objects or struck by swinging object by energy absorption. Upon hitting by an object, the ,helmet, dissipates some of the energy in the following mechanisms: (i) Stretching of harness ,inside, the ,helmet,; (ii) Partial damage of outer shell of ,helmet,.
When you are wearing a ,helmet, during a fall or crash, the force of impact is distributed over the surface of the ,helmet,, rather than concentrated on the head. In addition, the thick plastic foam (firm polystyrene) ,inside, the hard outer shell of a ,helmet, provides protection that cushions the blow.
All UniSafe helmet shells are made from premium impact resistant ABS plastic or polycarbonate. In compliance with the standards objectives, specifying safety helmets is dependent on hazards involved. AS/NZS 1801:1997 classifies safety helmets into three types: UniSafe Saftey helmets: Type 1- General industrial safety helmets.
The main impact absorbing material in a cycling helmet is, therefore, a moulded block of polystyrene foam, usually with a polycarbonatecovering. These materials are easily shaped - cycling helmets often have striking shapes to improve their aerodynamic performance. Manufacturing.
EN 397: The European standard code of practice (EN 397) provides guidance for manufacturers of ,safety helmets, to ensure that minimum ,material, grades are used. It also establishes the requirements for the testing of ,safety helmets,, as ,safety helmets, must be designed to protect the wearer from falling objects.
KEP Italia helmets feature a polycarbonate and carbon fiber combination. Polycarbonate is a pliable material commonly used in eyeglasses, greenhouses, digital discs, etc. The impact strength of polycarbonate rates towards the top for impact strength, but can be susceptible to scratching.
